D2.His.9.9-12: Sources and the Interpretations Made from Them: The Legend of Marcus Whitman
In plain English: D2.His.9.9-12 is the C3 Framework history indicator for grades 9-12 that asks students to analyze the relationship between historical sources and the secondary interpretations made from them. Students trace how an interpretation rests on, reads, reaches beyond and even reshapes its sources, using the century-long debate over whether Marcus Whitman rode east in 1842 to save Oregon.
Analyze the relationship between historical sources and the secondary interpretations made from them.
C3 Framework for Social Studies (NCSS) · Dimension 2: Applying Disciplinary Concepts and Tools · Discipline: History · Historical Sources and Evidence · Official standard
Every secondary interpretation has a relationship with its sources, and that relationship runs both ways. An interpretation rests on some sources and not others, reads them well or badly, reaches beyond them to fill silences, and sometimes rebounds on them, when a printed story shapes what later witnesses remember. This lesson teaches students to map those four relationships, using one of the best-documented debates in American historiography: did the missionary Marcus Whitman ride east in the winter of 1842-43 to save Oregon for the United States?
Students read the story as Oliver Nixon told it in 1895 (Source 1), the 1848 obituary that Edward Gaylord Bourne set against it in 1901 (Source 2), Bourne's case that the story rests on recollections set down from 1864 on (Source 3), a letter Whitman himself sent to the Secretary of War (Source 4) and Myron Eells's 1902 reply defending the story (Source 5). The goal is not to award the debate to one side, but to explain how each interpretation was built from, and limited by, its sources. Two SVHS-written sample interpretations (Source 6) give the homework a test case.
Learning Objectives
By the end of this lesson, students will be able to:
Identify the sources a secondary interpretation rests on and date each one against the events it describes
Judge whether an interpretation reads its sources accurately, using the sources' own words
Explain where an interpretation reaches beyond its sources, for example by explaining a silence in the record
Analyze how a published interpretation can shape later sources, such as recollections recorded after the story was in print
Compare how two interpretations draw different conclusions from the same source or the same gap in the evidence
Prior Knowledge Required
Students should already be comfortable with:

Comparing treatments of the same topic in several primary and secondary sources RH.9-10.9
Background on the Oregon Country in the 1840s: the United States and Great Britain both claimed it until a treaty in 1846, and American emigrants began crossing the Oregon Trail in the early 1840s
"A famous story about your school says that a student once saved the championship game with a last-second shot. Nobody wrote about it at the time; the story first appears in a yearbook article twenty years later, and since then several alumni say they remember it. What would you want to check before you believed it, and why might the alumni's memories not settle the question?"
Collect answers on two lists: "what to check" (a box score or newspaper from that week, the yearbook writer's own source) and "why memories might not settle it" (they read the yearbook article; they want the story to be true; twenty years is a long time). Tell students that historians faced exactly this problem with a story about the Oregon Trail, and that the argument over it is a model for how sources and interpretations depend on each other.
Direct Instruction20 minutes
Give the background in two minutes: Marcus Whitman and his wife Narcissa ran a mission of the American Board of Commissioners for Foreign Missions at Waiilatpu, near present Walla Walla, from 1836. In October 1842 Whitman rode east across the mountains in winter, and in 1843 he went back west with the large emigration of that year. In November 1847 he, his wife and others at the mission were killed in an attack by Cayuse men (see the teacher note in Closure). Then introduce the Source-Interpretation Map, an SVHS teaching tool.
The Source-Interpretation Map (an SVHS teaching tool): four relationships between an interpretation and its sources
Relationship
Question to ask
What to write down
1. Rests on
Which sources does the claim depend on, and when was each made, relative to the events?
The sources, with dates; whether each is from the time or a later recollection
2. Reads
Does the interpretation report what those sources actually say?
A quotation from the source next to the interpretation's version
3. Reaches
Where does the claim go beyond the sources, and how does it fill the gap?
The gap (a silence, a missing motive) and the inference used to fill it
4. Rebounds
Did the interpretation shape later sources, for example witnesses who had read it?
Dates of publication against dates of testimony
1The Doctor set about his active preparations, arranging his outfit and seeing that everything was in order. The next day he had a call to see a sick man at old Fort Walla Walla, and as he needed many articles for his journey which could be had there, he went with this double purpose. He found at the Fort a score or more of traders, clerks and leading men of the Hudson Bay Company, assembled there. They were nearly all Englishmen, and the discussion soon turned upon the treaty, and the outlook, and as might be inferred, was not cheering to Whitman. But his object was to gain information and not to argue.
[...]
2But while the company were enjoying their repast, an express messenger of the company arrived from Fort Colville, three hundred and fifty miles up the Columbia, and electrified his audience by the announcement that a colony of one hundred and forty Englishmen and Canadians were on the road.
3In such a company it is easy to see such an announcement was exciting news. One young priest threw his cap in the air and shouted, "Hurrah for Oregon--America is too late, we have got the country."
4Dr. Whitman carefully concealed all his intentions--in fact, this was enjoined upon all the missionary band, as publicity would likely defeat any hope of good results. Those who will take the pains to read Mrs. Whitman's diary will notice how she avoids saying anything to excite comment regarding the purposes of his winter visit to Washington. In her letter to her father and mother she simply says: "I expect my dear husband will be so full of his great work that he will forget to tell you of our life in Oregon. He can explain what it is," etc.
[...]
5As soon as the Doctor could with politeness excuse himself, he mounted his pony and galloped away home, pondering the news he had received. By the time he reached Waiilatpui he resolved there must be no tarrying for "five days." On the morning of the third day after the conference the spirit was upon him, and he took such messages as were ready, and on October 3d, 1842, bade a long good-bye to his wife and home, and the two men, their guide, and three pack mules, began that ever memorable journey [...]

1Sixty-six years ago, Marcus Whitman, a physician in Wheeler, Steuben Co., N. Y., received an appointment from the American Board of Commissioners for Foreign Missions to assist the Rev. Samuel Parker in establishing a mission among the Indians of the Oregon Territory. Upon their arrival at Green River (in Wyoming) Dr. Whitman decided to return to enlist more help. Early the next year he started out again with his bride, accompanied by the Rev. and Mrs. Henry H. Spalding and Mr. W. H. Gray, whom he had induced to join him in his arduous enterprise. Eleven years later, in November 1847, the energetic and faithful missionary with his wife and twelve other persons were massacred at their Station Waiilatpu, now Walla Walla, by the Cayuse Indians. The simple chronicle of Dr. Whitman's life as recorded in the obituary notice seven months later in The Missionary Herald, the official organ of the Mission Board, reads as follows:
2"Doct. Whitman was born in Rushville, in the State of New York, September 4, 1802. He joined the Church in that place in January, 1824; though he dated his conversion from a revival in Plainfield, Massachusetts, in 1819. He gave himself to the missionary work in 1834. In February, 1835, he went to Oregon for the first time. Having returned the same year, he was married in February, 1836; and in the following month he set out a second time for his chosen field of labor. He made a visit to the Atlantic States in the spring of 1843, being called hither by the business of the mission. He was a diligent and self-denying laborer in the the work to which he consecrated his time and energies. In the last letter received from him, he described at considerable length his plans and hopes in regard to the Indians, showing his interest not only to the Kayuses, but in more distant tribes."
3Fifty-two years later, in the most careful appraisal of human achievement in America that has ever been made, the voting for the Hall of Fame at New York University, Marcus Whitman received nineteen out of a possible ninety-eight votes to be ranked as one of the fifty greatest Americans. In the class of missionaries and explorers he stood fourth, being surpassed by Adoniram Judson with thirty-five, Daniel Boone with thirty-four, and Elisha Kent Kane with twenty-one votes, and followed by Frémont and George Rogers Clark with seventeen, Houston with fourteen, and Meriwether Lewis with thirteen votes. Turning to the voters we find Whitman ranked first in his class by the college Presidents, receiving ten votes from twenty-five voters.

Rests on: dating the dinner scene (Sources 1 and 3)
Nixon (1895) tells the dinner at Fort Walla Walla as fact: an express messenger announces "a colony of one hundred and forty Englishmen and Canadians," and a priest shouts "America is too late" (Source 1, paragraphs 2-3). He cites no source for the scene.
Result: Bourne dates the evidence: "The story first emerges over twenty years after the events" (Source 3, paragraph 1), and its first printed version came from Spalding "in the fall of 1865" (Source 3, paragraph 4). So Nixon's scene rests on accounts printed about 23 years after the ride, not on any record made in 1842.
Reads: the 1848 obituary (Source 2)
Seven months after Whitman's death, the Mission Board's magazine summarized his life (Source 2, paragraph 2). What does it say about the trip east?
Result: It says he "made a visit to the Atlantic States in the spring of 1843, being called hither by the business of the mission," and it says nothing about Oregon policy or Washington. It was printed in "the official organ of the Mission Board" (Source 2, paragraph 1). That silence is part of the record, and any interpretation of the ride has to account for it.
Reaches: explaining a silence (Source 1, paragraph 4)
Nixon admits that Mrs. Whitman's diary "avoids saying anything to excite comment regarding the purposes of his winter visit to Washington." How does he deal with that gap?
Result: He reads the silence as secrecy: "Dr. Whitman carefully concealed all his intentions," since "publicity would likely defeat any hope of good results." The missing evidence is turned into support for the claim. The inference may be possible, but no source on this page shows the concealment itself, so the claim reaches past its evidence.
Rebounds: witnesses and the printed story (Source 3, paragraph 2)
Bourne notes that the testimony for the story is "of earlier date than 1864" in no case. Why does the order of dates matter to him?
Result: Because "nearly all of it is subsequent to the publication of the story," and much of it "repeats the gross historical errors of the story as originally published." If witnesses took errors from the printed narrative, the interpretation shaped its own sources, and the testimony cannot count as independent support.
Guided Practice20 minutes
Read Source 3 together, then Source 4. Source 4 is a primary source from the time: a letter Whitman sent to the Secretary of War, which the War Department received on June 22, 1844. Nixon printed it in his own book's appendix, so both sides of the debate could read it. In pairs, students fill one row of the Map for each side: how would a defender of the story use this letter, and how would a critic?
1The essential points in this statement are the cause and purpose of Dr. Whitman's journey to the East in 1842, his influence on the Oregon policy of the government and his organization of the great immigration of 1843. Incidental or collateral assumptions usually accompany this statement to the effect that great ignorance and indifference in regard to Oregon prevailed in Washington and generally throughout the United States, and that Dr. Whitman was able to dispel the ignorance and to transform the indifference into a deep and widespread interest. In both the essentials and the explanatory details the story of how Marcus Whitman saved Oregon is fictitious. It is not only without trustworthy contemporary evidence, but is irreconcilable with well established facts. No traces of knowledge of it have ever been found in the contemporary discussion of the Oregon question. The story first emerges over twenty years after the events and seventeen years after Whitman's death and its conception of the Oregon policy of the government is that handed down by tradition in an isolated and remote community.
2The evidence advanced in support of this story is exclusively the oral testimony of a small group of people who have alleged that their accounts rested on Whitman's words or upon their own recollections. None of this testimony is of earlier date than 1864, and nearly all of it is subsequent to the publication of the story in its most complete form. As much of it repeats the gross historical errors of the story as originally published, it is difficult to escape the conclusion that if these witnesses derived these errors from the printed narrative they probably derived other features of their testimony from the same source. If this is made probable, it does not necessarily convict these witnesses of conscious dishonesty. No one who appreciates the fallibility of human memory as an instrument of precision and understands the subtle influence upon the mind of suggestion need be confronted by the painful dilemma that either they must reject the evidence of their reasoning powers or believe that venerated friends have been dishonest. Again most of the controversy in regard to this matter has involved religious and sectarian interests and has been conducted in large measure by people at once untrained in weighing evidence and profoundly interested in the final judgment.
3So far then as the oral testimony or written discussion is found inconsistent with the historical facts such inconsistency may be accounted for either as a conscious effort to deceive, an unconscious perversion owing to suggestion and inaccurate recollection, or as a misinterpretation of the evidence owing either to ignorance or bias.
4The original account of Whitman's journey, its causes, purpose, and results was first published in a series of articles in The Pacific, a religious paper in San Francisco, in the fall of 1865, contributed by the Rev. H. H. Spalding, a colleague of Dr. Whitman in the Oregon mission.

1The Rev. Myron Eells obtained from the original files of the office of the Secretary of War two valuable papers. They bear this endorsement:
2"Marcus Whitman inclosing synopsis of a bill, with his views in reference to importance of the Oregon Territory, War. 382--rec. June 22, 1844.
3To the Hon. James M. Porter, Secretary of War:
4Sir--In compliance with the request you did me the honor to make last Winter, while in Washington, I herewith transmit to you the synopsis of a bill which, if it could be adopted, would, according to my experience and observation, prove highly conducive to the best interests of the United States, generally, to Oregon, where I have resided for more than seven years as a missionary, and to the Indian tribes that inhabit the immediate country. The Government will now doubtless for the first time be apprised through you, or by means of this communication, of the immense immigration of families to Oregon which has taken place this year. I have, since our interview, been instrumental in piloting across the route described in the accompanying bill, and which is the only eligible wagon road, no less than three hundred families, consisting of one thousand persons of both sexes, with their wagons, amounting to one hundred and twenty, six hundred and ninety-four oxen, and seven hundred and seventy-three loose cattle.
Marcus Whitman, as printed by Oliver W. Nixon, Letter to the Secretary of War, received June 22, 1844 (Source 4: the opening, with the editor's introduction) (1844; this edition 1895). Public domain (published 1895). Source text.
Key. A defender rests on the letter's proof that Whitman met the Secretary in Washington ("the request you did me the honor to make last Winter, while in Washington"; "since our interview," paragraph 4) and that he worked for the emigration and for Oregon's place in national policy. A critic reads the same paragraph differently: Whitman writes that the government "will now doubtless for the first time be apprised" of the emigration. In his own book, Bourne argues in a note (page 89) that Whitman would not have written this way if he had pledged to the President to lead that emigration. Neither reading is a misquotation: the letter is compatible with a national interest, but it does not show that national business was the cause of the ride. Ask: Bourne offers three explanations for an inconsistency in paragraph 3. Which one would Eells most strongly reject for the witnesses he knew, and why?
Independent Practice20 minutes
Students read Source 5, Myron Eells's 1902 reply to Bourne, and write a Map entry for Eells's own argument: what does he say about the relationship between missing records, recollections and the truth? Then they answer in a paragraph: on which point is Eells's criticism of Bourne strongest, and on which point is Bourne's method stronger? Quiz Questions 12-16 and 19 use Source 5.
1Although Professor Bourne makes much of this want of evidence at the missionary rooms at Boston, in Mrs. Whitman's letters, and in other writings that Dr. Whitman went east for national reasons, as a strong proof that he had no such reasons, it reminds the writer of the story of the five witnesses in court who testified that they saw the prisoner murder his fellow being, but because ten men appeared who stated that they did not see the murder committed the prisoner was cleared. [...]
2[...] If Professor Bourne can find a plain statement at Boston or in Mrs. Whitman's letters or by any good authority previous to 1864 that Dr. Whitman did not go east for national reasons, let him make it known, but if not, the absence of evidence in certain places is not conclusive proof that Dr. Whitman did not go east for those reasons.
3(c) Professor Bourne holds that the recollections of persons who were acquainted with Dr. Whitman are of little or no value, when stated many years afterwards, if they are unsupported by written cotemporary evidence, for it is not scientific history. He rejects the evidence of many witnesses because they published nothing until 1864, and so the evidence depends on the memories of persons twenty-one years or more after the events took place. He refers (p. 71) to two books, "Introduction to the Study of History," and "Pierce's Recollections as a Source of History," to sustain him in his position. This address, delivered in June, 1901, was offered to the American Historical Review for publication, but was declined in a very gentlemanly letter by the editor in chief because "it rests largely on the remembrance of the old." He also added, "Scientific historical students know from innumerable tested cases that extremely little confidence can be reposed in recollections set down long after the events, even when several of them closely agree."
4If the editor had lived as long on the Pacific coast as he has on the Atlantic he would have learned that one great object of the State Historical Societies is to write down the historical statements of many individuals before they shall die and their knowledge be lost forever. There have been many men on the Pacific coast who never had much education and who find it a great task to write a little, who have made and witnessed the making of a large amount of history, not knowing its importance at the time, and even others did not realize it until later events showed the importance of these facts. These societies are glad to record their evidence from thirty to sixty years after the events transpired. [...] The writer has no objection to scientific history as above defined, namely the facts written at or near the time they occurred. He has tried to obtain all such scientific history that he could for all of his writings. He has searched old books, pamphlets and letters for it. He thinks highly of it, and more highly of only one thing and that is the truth. This he places above everything. Generally scientific history and truth agree, but sometimes in order to obtain the truth it is necessary to go outside of scientific history, and sometimes scientific history is not the truth. [...]

Exit ticket: "Name one thing an interpretation can do to a source that a source cannot do to an interpretation, and one thing a source can do to an interpretation." (Sample: an interpretation can shape what later witnesses remember; a source can limit what an interpretation can honestly claim.) Introduce Source 6 for the homework.
Teacher notes. (1) Sources 1-3 and 5 were written between 1895 and 1902 and use the language of their time, including "Indians," "Kayuses" and Bourne's word "massacred." In class, call the events of November 1847 the attack or the killings at Waiilatpu. The National Park Service, which presents the site history in partnership with the Confederated Tribes of the Umatilla Indian Reservation, says on its FAQ page that the word "massacre" "gives an inaccurate impression of this tragic event": "Thirteen people were killed in the initial attack," women and children other than Mrs. Whitman were not killed, and most people at the mission were taken hostage and held for a month. (Bourne's count, Whitman, his wife and twelve others, differs from the Park Service's count for the initial attack; students can note the difference.) Give students the Cayuse perspective that the 1895-1902 writers leave out. The Park Service calls the mission years "a pivotal moment for Cayuse and other Native people living on the Columbia Plateau." On its park home page it says that "after thousands of years of habitation by the Cayuse Nation," life on the Plateau "begins to change rapidly with the influx of missionaries, newcomers from the Oregon Trail, and diseases," and it describes the attack as "a single violent act of desperation to protect a community." It also notes that the mission was later burned "in retaliation for lodges which had been destroyed by the Oregon Volunteers." The Cayuse are a nation with their own history, not only figures in a missionary story, and their descendants live in the region today as part of the Confederated Tribes. (2) The debate also had a religious side: Bourne notes that it "involved religious and sectarian interests" (Source 3, paragraph 2), and some writers of the period used hostile language about Catholics; the excerpts here leave that language out, and the lesson takes no side on religious questions. (3) Source 6, Interpretation A, contains deliberate errors for the homework, and its label on the page says so; do not present it as a reading of the evidence.
1Interpretation A (SVHS-written sample, written with deliberate errors for the homework to find). Marcus Whitman cared only about his mission and had no interest in the future of Oregon. Bourne proved in 1901 that the story of the dinner at Fort Walla Walla was invented, so every part of the "saved Oregon" story is false. The 1848 obituary in The Missionary Herald says he went east "by the business of the mission," and that one sentence settles the question.
2Interpretation B (SVHS-written sample). The earliest printed account of Whitman's life, the 1848 obituary, says he went east on mission business, and no account of the dramatic dinner at Fort Walla Walla appeared in print until more than twenty years after the ride. Bourne therefore treats the dinner story as a legend that later witnesses absorbed from print. Eells answers that silence in the records does not prove Whitman had no national purpose, and Whitman's own 1844 letter shows that he did meet the Secretary of War in Washington and helped guide about a thousand emigrants on the road to Oregon. The evidence supports a narrower claim than Nixon's: Whitman went east on mission business and became an advocate for American settlement, but the story that he rode east to stop Oregon from being traded away rests on recollections set down from 1864 on.

Differentiation Strategies
For Struggling Students
Give a timeline strip with five dates already marked (October 1842, 1844, 1848, 1865, 1895) and have students place each source on it before using the Map
Pre-teach five terms: secondary interpretation, contemporary (made at the time), recollection, legend and sectarian (tied to a religious group)
Assign only Map rows 1 and 2 for Source 5, with a sentence frame: "Eells says missing records do not prove ___ because ___."
For Advanced Students
Have students write Bourne's reply to Eells's argument about "the absence of evidence" (Source 5, paragraph 2), using Bourne's own words from Source 3
Ask students to apply the Map to a modern interpretation they know, such as a documentary, and name one place where it reaches beyond its sources
Ask whether Eells's defense of recollections (Source 5, paragraph 4) would hold for a modern oral history project, and what safeguards it would need
Assessment Guidance
What to Look For
Strong work dates every source against the events (1842, 1844, 1848, 1865 and after), quotes both the source and the interpretation when judging a reading, and names the inference an interpretation uses to cross a gap. The best answers see the relationship in both directions: sources limit interpretations, and printed interpretations can shape later sources. Watch for students who simply declare a winner ("Bourne proved it was false") without explaining what the evidence can and cannot show, and for students who treat a silence in the record as proof either way.

Evidence Timeline
15 minGroups of 3-4
Each group gets 10 date cards and a long strip of paper. Groups place the cards in order, then draw two colors of arrows: blue for "rests on" (from a source to the interpretation that uses it) and red for "rebounds" (from a printed interpretation to later testimony it may have shaped). Each card names the source on this page that gives the date.
The 10 Cards
October 3, 1842: Whitman leaves Waiilatpu on his ride east (Source 1)
Winter 1842-43: Whitman meets the Secretary of War in Washington (Source 4)
June 22, 1844: The War Department receives Whitman's letter (Source 4)
November 1847: Whitman, his wife and others are killed at Waiilatpu (Source 2)
1848: The Missionary Herald prints his obituary (Source 2)
1864: Earliest testimony for the "saved Oregon" story (Source 3)
Fall 1865: Spalding's articles in The Pacific print the story (Source 3)
1895: Nixon publishes How Marcus Whitman Saved Oregon (Source 1)
1901: Bourne publishes "The Legend of Marcus Whitman" (Source 2)
1902: Eells publishes his reply to Bourne (Source 5)
Answer Key for the Teacher
The cards are already in order above; shuffle them before class. Blue arrows: the 1844 letter and the 1848 obituary to Bourne (1901); Spalding's 1865 articles to Nixon (1895); Spalding's story and the testimony that followed it to Eells (1902), who defends the witnesses; the 1844 letter to Nixon, who printed it in his appendix. Red arrow: Spalding's printed story (1865) to the testimony that followed it, as Bourne argues in Source 3, paragraph 2. Discuss the gap: no card between the 1848 obituary and the 1864 testimony carries the story, a span of 16 years.

Structured Controversy: Can Late Recollections Support a Claim?
20 minGroups of 4 (two pairs)
The question: "Can recollections written down twenty or more years after an event support a historical claim?" One pair prepares Bourne's position from Source 3, the other Eells's position from Source 5. Each pair presents for two minutes, using at least two quotations; the other pair restates the argument to the first pair's satisfaction. Then the pairs switch sides, and finally the group writes one consensus sentence.
Preparation Notes
Bourne's pair: find his explanation of why testimony from after the story was printed is weak, and his three possible causes of an inconsistency (Source 3, paragraphs 2-3).
Eells's pair: find his argument about missing records and his case for recollections (Source 5, paragraphs 2-4).
Both pairs: note one thing the other side gets right.
Sample Consensus Statement
"Late recollections can support a claim when they are independent of each other and of any printed version, and when records made at the time do not contradict them; recollections recorded after a story was in print need to be checked against sources from before it." Accept any consensus that names a condition, not just a yes or no; the rubric scores reasoning, not the side.

The Rebound Test (an Invented Case)
15 minPairs
An invented scenario lets students run Bourne's test on fresh evidence. In the invented town of Cedar Bend, a 1975 newspaper article first prints the story that the town's founder rode to the state capital in 1950 "through a blizzard" to stop a new highway from bypassing the town. Weather records for that week show no snow. Pairs study ten invented statements by townspeople and decide how much support they give the story.

Questions
How many statements were recorded before the 1975 article, and how many after it?
How many of the statements recorded after 1975 repeat the blizzard detail, which the weather records contradict?
Do the statements from before 1975 support the highway purpose?
Using Bourne's reasoning in Source 3, paragraph 2, how much independent support do the ten statements give the story?
Answer Key for the Teacher
(1) 2 before (W1, W2) and 8 after (W3-W10). (2) 6 of the 8 (W3, W4, W6, W7, W9, W10). (3) No: neither W1 nor W2 mentions the highway. (4) Little: every statement that supports the highway purpose came after the article, and most of them repeat its error, which suggests they drew on it. Like Bourne's witnesses, they "probably derived other features of their testimony from the same source." Students should add Eells's caution: W5 and W8 give the purpose without the error, so the story is not disproved, only unsupported by independent early evidence.

The four relationships in the SVHS Source-Interpretation Map, drawn for the Whitman debate. Three arrows run from the sources to an interpretation: what it rests on, how it reads them, and where it reaches past them into a gap. The red arrow runs the other way: Bourne argues that the printed story of 1865 shaped testimony recorded after it.
Diagram 2: When the Sources Were Made
A timeline drawn to scale, 1840-1905. The records made at the time (the 1844 letter and the 1848 obituary) sit close to the 1842 ride; the testimony and the printed story begin in 1864-1865, and the three interpretations on this page appear from 1895 to 1902. Dates come from Sources 1-5.

For every answer, quote the interpretation and the source it uses, and name the Map relationship you are testing (rests on, reads, reaches or rebounds).
Part 1: Testing Interpretation A (Problems 1-3)
Interpretation A quotes the obituary as saying Whitman went east "by the business of the mission." Compare the quotation with Source 2, paragraph 2. Are the words accurate, and does the obituary support A's claim that this one sentence "settles the question"?
Interpretation A says Whitman "had no interest in the future of Oregon." Which source on this page contradicts that claim? Quote it and explain the contradiction.
Interpretation A treats Bourne's verdict as the end of the debate. Name one argument from Source 5 that a careful interpretation would have to answer, and explain whether the evidence Bourne gives in Source 3 answers it.
Part 2: Building on Interpretation B (Problems 4-6)
Interpretation B says no account of the dinner appeared in print "until more than twenty years after the ride." Which sources on this page support the claim, and what kind of new source would overturn it?
Interpretation B and Nixon both use Whitman's letter (Source 4), but for different purposes. Explain how B reads the letter, and whether B's reading stays within what the letter says.
Write your own interpretation (5-7 sentences) of why Whitman rode east in 1842. Cite at least three sources from this page, and include one sentence that says where the evidence runs out. Any position is acceptable if the reasoning follows the sources.

Question 1 of 20 · Multiple Choice
A historian's claim about a meeting in 1850 depends mainly on memories that witnesses wrote down in 1872. Which Map question addresses this problem most directly?
Answer: C
The problem is the kind and date of the evidence: recollections set down 22 years later. That is the "rests on" question. A could also be checked, but accurate quotation does not fix late evidence; B and D describe other relationships that the scenario does not mention.
Question 2 of 20 · Multiple Choice
According to Source 1, paragraph 1, why did Whitman go to Fort Walla Walla?
Answer: A
Nixon writes that "he had a call to see a sick man" and "needed many articles for his journey which could be had there, he went with this double purpose." B and C are not in the paragraph; D confuses the express messenger "from Fort Colville" (paragraph 2) with a priest.
Question 3 of 20 · Multiple Choice
Nixon quotes the young priest's words at the dinner (Source 1, paragraph 3). What would a historian most need to accept the quotation as evidence?
Answer: C
A quotation is only as good as the record behind it: someone present, writing near the time. A repeats the claim without new evidence; B tells us about Nixon, not about 1842; D is the "rebound" problem, since readers of the book are not independent witnesses.
Question 4 of 20 · Multiple Choice
In Source 2, paragraph 3, why does Bourne describe the Hall of Fame vote of 1900?
Answer: B
Bourne sets the 1848 "simple chronicle" (paragraph 1) beside a vote that ranked Whitman among "the fifty greatest Americans" 52 years later. The gap is his point. A is a claim the vote cannot show; C misreads his remark about the presidents' votes; D reverses the comparison.
Question 5 of 20 · Multiple Choice
The obituary in Source 2 appeared in "the official organ of the Mission Board." What objection could a defender of the "saved Oregon" story raise about it?
Answer: C
A magazine of the Mission Board, writing about a missionary, had reason to report mission business and little reason to discuss national politics; its silence is not proof, as Eells argues in Source 5. A is wrong: it came "seven months later." B and D have no basis in the source.
Question 6 of 20 · Multiple Choice
Which of these is NOT one of the grounds Bourne gives in Source 3, paragraph 1, for calling the story fictitious?
Answer: D
Bourne says the story is "without trustworthy contemporary evidence," "irreconcilable with well established facts," and that "No traces of knowledge of it" appear in "the contemporary discussion." D is invented, and Source 4 shows the opposite: Whitman refers to "our interview."
Question 7 of 20 · Multiple Choice
Why does Bourne say his conclusion "does not necessarily convict these witnesses of conscious dishonesty" (Source 3, paragraph 2)?
Answer: A
He points to "the fallibility of human memory" and "the subtle influence upon the mind of suggestion": people can repeat what they read and believe they remember it. B, C and D are not in the passage, and C contradicts it, since none of the testimony is earlier than 1864.
Question 8 of 20 · Multiple Choice
At the end of Source 3, paragraph 2, Bourne says the controversy was conducted by people "untrained in weighing evidence and profoundly interested in the final judgment." What problem is he naming?
Answer: B
Being "profoundly interested in the final judgment" means caring about the outcome, here because the debate "involved religious and sectarian interests." That can bend how an interpreter reads sources. A, C and D are not in the paragraph.
Question 9 of 20 · Multiple Choice
What does Source 4, paragraph 1, tell you about how this letter reached the debate?
Answer: C
The editor writes that "The Rev. Myron Eells obtained from the original files of the office of the Secretary of War two valuable papers." A defender of the story searched government records made at the time, which is the kind of source Bourne asked for. A, B and D are not in the paragraph.
Question 10 of 20 · Multiple Choice
In Source 4, paragraph 4, Whitman calls his route "the only eligible wagon road" and asks the government to adopt his bill. How should a historian treat these statements?
Answer: A
Whitman is arguing for a bill he drafted, so the letter is evidence of his views and goals, to be checked against other sources. B confuses filing with neutrality; C reaches past the letter, which is about the emigration and the road; D is wrong, since the War Department received it in June 1844.
Question 11 of 20 · Multiple Choice
Source 4, paragraph 2, quotes the War Department's endorsement, "rec. June 22, 1844." Why is a date written by the office that received a letter strong evidence for dating it?
Answer: D
The receiving office wrote the note when the letter arrived, so the date does not depend on the writer's memory or on a later editor. A overclaims, since clerks could err; B confuses dating a document with confirming its contents; C is an unsupported generalization.
Question 12 of 20 · Multiple Choice
What is the point of Eells's story of the five witnesses and the ten men (Source 5, paragraph 1)?
Answer: B
Eells compares the missing evidence in Boston and in Mrs. Whitman's letters to "ten men" who "did not see the murder committed": not seeing is not evidence against those who saw. A misreads the analogy as a count of real witnesses; C and D draw conclusions Eells does not.
Question 13 of 20 · Multiple Choice
In Source 5, paragraph 2, what does Eells challenge Bourne to produce?
Answer: A
Eells writes: "If Professor Bourne can find a plain statement ... previous to 1864 that Dr. Whitman did not go east for national reasons, let him make it known." B, C and D are kinds of evidence Eells does not ask for; B would in fact help Eells's side.
Question 14 of 20 · Multiple Choice
According to Source 5, paragraph 3, why did the American Historical Review decline Eells's address?
Answer: C
The editor declined it because "it rests largely on the remembrance of the old," adding that "extremely little confidence can be reposed in recollections set down long after the events." A, B and D are not in the source.
Question 15 of 20 · Multiple Choice
In Source 5, paragraph 4, which kind of source does Eells defend?
Answer: D
He praises State Historical Societies that "record their evidence from thirty to sixty years after the events," from people who "find it a great task to write a little." A, B and C are records made at the time, the kind he calls "scientific history" and says he also uses.
Question 16 of 20 · Short Answer
Does Eells's story of the five witnesses (Source 5, paragraph 1) fit the Whitman case? Use Bourne's argument in Source 3, paragraph 2, in your answer.
Model answer: Only partly. The analogy assumes five independent eyewitnesses who saw the event. Bourne argues that the testimony for the story is not like that: none of it is "of earlier date than 1864," nearly all of it came after the story was printed, and much of it "repeats the gross historical errors" of the printed version. If the witnesses drew on the printed story, they are not five separate sightings. Eells is right that silence alone does not disprove a claim, but his analogy does not answer the dating problem. Rubric: full credit for testing the analogy's assumption of independent witnesses against Bourne's dates; partial credit for summarizing both sides without testing the fit.
Question 17 of 20 · Short Answer
Compare what the 1848 obituary (Source 2, paragraph 2) and Nixon (Source 1) say about the purpose of Whitman's trip east. Explain why Bourne gives the obituary more weight, and give one reason a defender of the story might give it less.
Model answer: The obituary says he was "called hither by the business of the mission"; Nixon tells of the news at the dinner and a hidden plan to reach Washington. Bourne prefers the obituary because it was printed in 1848, close to the events, by the Board that sent Whitman, before any version of the dinner story existed. A defender could answer that a mission magazine had reason to describe mission business only, and that Nixon himself says the purpose was kept secret, so silence in a Board publication is expected. Rubric: full credit for both accounts quoted, a reason based on date or maker, and a fair counter-reason.
Question 18 of 20 · Short Answer
Bourne says the story's "conception of the Oregon policy of the government is that handed down by tradition in an isolated and remote community" (Source 3, paragraph 1). Explain what he means, and how this claim connects to the kinds of sources the story rests on.
Model answer: Bourne means that the story's picture of what Washington knew and planned about Oregon came from beliefs passed along among settlers in the Oregon country, far from the capital, not from the records of the government or the national debate. He backs this with the absence of the story from "the contemporary discussion of the Oregon question." The connection: a story built from local tradition and later recollections will reflect what a community came to believe, so it needs to be checked against national records made at the time, such as debates and official correspondence. Rubric: full credit for explaining "tradition in an isolated and remote community" and linking it to the gap between local recollection and records made at the time.
Question 19 of 20 · Short Answer
In Source 5, paragraph 4, Eells says that "sometimes scientific history is not the truth." Explain what he means by "scientific history," and give one strength and one risk of his approach.
Model answer: By "scientific history" Eells means "the facts written at or near the time they occurred," records made at the time. He argues that many people who made history left no writing, so their recollections, even decades later, may hold truths the records miss. Strength: it brings in people who never wrote, such as the settlers he mentions. Risk: late recollections can be shaped by memory loss and by what people later read, which is Bourne's point about suggestion. Rubric: full credit for his definition, one strength and one risk tied to the sources.
Question 20 of 20 · Short Answer
Bourne lists three ways an inconsistency between testimony and the facts can arise (Source 3, paragraph 3). Choose the one you think best fits Nixon's dinner scene in Source 1, and explain what evidence would show whether you are right.
Model answer: "A misinterpretation of the evidence owing either to ignorance or bias" fits Nixon best: he wrote in 1895, more than fifty years after the ride, and reads Mrs. Whitman's silence as secrecy, which suggests a strong belief in the story rather than deception. Evidence: Nixon's own sources for the scene (if they all date from 1865 or later, he inherited the story), and any record from 1842 of the express from Fort Colville or of the colony of "Englishmen and Canadians" said to be on the road. Another choice is acceptable with a reason and a test. Rubric: full credit for one explanation applied to Nixon with a reason and a concrete test; partial credit without a test.

Frequently Asked Questions
10 Questions
What does D2.His.9.9-12 mean?
D2.His.9.9-12 asks high school students to analyze the relationship between historical sources and the secondary interpretations made from them. Students ask what an interpretation rests on, whether it reads its sources accurately, where it reaches beyond them and whether it shaped later sources in turn. This page practices those questions on the debate over Marcus Whitman's ride of 1842.
How is D2.His.9.9-12 different from D2.His.9.6-8?
In grades 6-8, students classify the kinds of sources an interpretation uses. In grades 9-12, they analyze how the interpretation and its sources relate: which sources it chose, how it read them, what it inferred, and how a published account can shape later testimony.
What is the "Whitman saved Oregon" story?
It is the claim that Marcus Whitman rode east in the winter of 1842-43 to warn the government and save Oregon from being lost to Great Britain. Oliver Nixon told it as fact in 1895. Edward Gaylord Bourne called it a legend in 1901, and Myron Eells defended it in 1902. This page uses the debate as a case study in evidence and does not hand students a verdict.
Why can a silence in the records not settle a historical question by itself?
Because a silence can have more than one cause: the writer may not have known, may not have thought the matter important, or may have had reasons not to say it. Historians weigh a silence together with other evidence before drawing a conclusion from it.
Can recollections written down years later be good historical evidence?
Yes, with checks. Recollections can hold facts that no record kept, but historians compare them with records made at the time and note when, and after what, they were set down.
What does it mean that an interpretation can "rebound" on its sources?
It means a published interpretation can shape the sources that come after it. Bourne argues that most testimony for the Whitman story was recorded after the story was printed in 1865 and repeated its errors, so the testimony may echo the interpretation rather than support it independently. "Rebound" is an SVHS label for this, not an official C3 term.
Is D2.His.9.9-12 taught in U.S. History or in a separate course?
It can sit in any high school history course. It fits naturally in U.S. History units on westward expansion or on how history is written, but the C3 Framework does not assign it to one course. This page uses U.S. History.
How should teachers handle the language and violence in these sources?
Teach them as documents of their time. The sources use period terms such as "Indians" and "massacred," and the National Park Service now says the word "massacre" gives an inaccurate impression of the 1847 attack. The lesson does not center the killings; it presents the Cayuse as a people with their own history and keeps to the evidence about the ride.
How is D2.His.9.9-12 assessed?
Through tasks that require students to connect an interpretation to its sources with quotations and dates, not through recall of who was right. The quiz and homework on this page ask students to test claims against sources, explain a silence, and write their own interpretation with an honest limit.
How does D2.His.9.9-12 connect to the Common Core literacy standards?
It pairs with RH.9-10.9 and RH.11-12.9, which ask students to compare and integrate primary and secondary sources, and with RH.11-12.8, which asks them to evaluate an author's claims and evidence by checking them against other information.
