The Eugene Opie Papers includes extracts from diaries from several of his peers that illuminate his notable career in pathology, most especially his work on tuberculosis in Jamaica between 1937-1941. The Opie Papers include typed, loose diary notes from three of his peers: Wilbur A. Sawyer, John M. Weir, and Edward W. Flahiff. Sawyer supplies brief notes related to a pair of meetings within scientists in Montegomery (6/20-6/21/1937) and at Cornell University (11/17/1937). Weir's notes record one year of hospital and asylum work in Jamaica (2/1/1939-1/31/1940), with regular references to tuberculin tests, injections, and vaccinations. Of note, Weir devotes about a week to research Yellow Fever (4/1-4/8/1940). Finally, Flahiff offers the most exhaustive account of the Jamaica efforts. Contained in three folders, his notes span two and half years of work (10/1/1938-5/14/1941). Notably, Flahiff makes regular mentions of Opie, and notes that cultural issues impede their medical work. For example, he writes, "Birth control propaganda continues to be a serious deterrent to our nurses' efforts in the field" (3/7/1939). Perhaps most notably, Flahiff registers the effects of World War II obliquely in his entries. He notes a "new contingent of soldiers in Jamaica…composed of Canadians who have replaced the English troops in the Island" (7/1/1940) and glosses a public holiday for a "Peacemaker's Day" with the parenthetical "(Why???)" (11/9/1940). Together, these three sets of diaries ought to interest scholars researching Eugene Opie's career in pathology, especially his work to address tuberculosis in Jamaica.
 

Plant physiologist and historian Rodney H. True kept 10 volumes of diaries sporadically. For the most part, the diaries written prior to 1917 include perfunctory daily notes on True's professional activities, with occasional personal comments, but the diaries for 1917-1919 include longer and more interesting passages. Although True was not a retrospective diarist, he commented regularly on the news from Europe and, to a lesser degree, on the home front, where he used his knowledge of agricultural science to assist in raising food for the war effort. The diaries for 1883 and 1926 are very brief, the latter being more an appointment book than a true diary.
 

Philadelphia physician Samuel George Morton helped shape the development of physical anthropology in antebellum America. His diary of a trip to the West Indies offers a case study in scientific racism. The volume includes various observations on life, work, agriculture, and slavery in Barbados and other islands. Notably, Morton's journal includes derogatory comments on the native inhabitants that researchers might choose to examine in tandem with other records available in the Samuel George Morton Papers, such his "craniometrical drawings," which were used by pro-slavery advocates. This diary may interest scholars examining slavery in antebellum science and racial thought, slavery in Barbados, and the history of the West Indies more broadly.
 

The James Brindley Diaries contain two volumes related to his work on the Susquehanna, Conewago, Chesapeake, and Delaware canals. The first, entitled "Susquehanna and Conewago Canal Diary" (9/2/1794-1/20/1795) features highly detailed entries with significant technical data related to the project. Interspersed throughout, Brindley remarks on technical and logistical problems he encounters. For example, he notes that after the Canal Board fails to provide wages to workers, he has to advance funds to purchase tools. Perhaps most notably, he records the tensions related to Whiskey Rebellion in western Pennsylvania in an extended passage excerpted in Selected Quotations. The volume also includes drafts of letters to William Smith and Robert Morris.
 
The second volume, "Chesapeake and Delaware Canal Diary" (1/18-6/10/1803) recounts his early work on the Chesapeake and Delaware Canals, which would not be completed for another twenty-five years on account of funding problems. Brindley registers those issues in his early diary, discussing some of the legal and financial problems facing the project.

An engineer in the early national period, James Brindley worked on a host of canal projects in the United States, including the Potomac Canal in Maryland and the James River Canal in Virginia. His diaries, available in two volumes, document his work on the Susquehanna and Conewago Canal in 1794-1795 and the Chesapeake and Delaware Canal in 1803. The Conewago Canal, financed by Robert Morris and completed in 1797, improved access to Philadelphia markets. While the Chesapeake and Delaware Canal was debated as early as the 1760s, it was not funded until 1802 (and continued funding challenges would delay its completion for another 25 years). Brindley served as the lead engineer for both projects, and his journal provides valuable insights into early-nineteenth century canals and engineering, the Whiskey Rebellion, and U.S. government funding problems in the early national period.

The first journal, "Diary of a Trip to England & Scotland in the Summer of 1912" documents a three-month trip (6/22-9/23) that Amelia and Philip Calvert took while attending the Second International Congress of Entomology. Given the numerous references to "P," it appears that Amelia maintained most if not all of this volume. The journal is remarkable for its variety of modes of transportation: the narrative begins with the transatlantic voyage from Philadelphia to Liverpool aboard a steamer (the S.S. Merion), and includes transport by sailboat, rail, carriage, auto, and funicular. Calvert also furnishes numerous descriptions of European towns and cities, architecture, people, dress, history, weather, and sightseeing of religious and cultural institutions. Notably, the journal includes occasional illustrations and ephemera such as advertisements, receipts, bills, and even a peacock feather (280).
 
The second journal, "Diary of Trip to Europe 1929" follows much the same structure. Once again, it provides an account of a several months travel (7/12-10/2) associated with work, this time a visit to the Zoologists Institute at Freiburg. The couple travels from New York to Antwerp by steamer (the S.S. Lapland). Alongside notes concerning sightseeing—and illustrations and ephemera—Calvert furnishes some comparative observations that might interest twentieth century historians. For example, she writes, "While there are many automobiles and trucks on the streets of Brussels, there is not yet the density of traffic to be seen in Philadelphia" (7/23/1929).

Amelia Smith Calvert maintained two journals of European trips taken in the summer of 1912 and 1929. Although both trips appear to coincide with scientific conferences, Calvert dedicates most of her entries to enthusiastic observations of sightseeing in the United Kingdom, Holland, Belgium, Germany, and Italy. These volumes may interest researchers exploring early-twentieth-century science and European travel.

Although the Loammi Baldwin Diary traverses just three months (9/9-11/29/1823), this volume provides a valuable record for researchers interested in antebellum travel, early-nineteenth century Europe, and urban architecture and mechanics, particularly the construction of canals and bridges. In fact, the highlight of this diary is less Baldwin's narratives of prominent European cities, including Amsterdam, Brussels, and Paris, than his remarkable illustrations of their architecture and mechanical structures. Reference his illustration of the floating bridge on Helder Canal in Amsterdam for a model of Baldwin's keen draftsmanship (11/1/1823).
 

The vast majority of the 33 volumes listed as "diaries" in the Raymond Pearl Papers might be better described as common-place books, though the collection includes at least six unbound volumes that might be accurately classified as diaries. Most of these entries pertain to various recreational European trips taken between 1905-1928. The 1905 diary includes numerous accounts of sightseeing in London, including visits to Kew Gardens (9/28), the Tower of London (9/30), and a theater, which Pearl compares to that of the United States (10/18). Pearl uses the next two journals, from 1916 and 1917 respectively, as field notebooks with miscellaneous accounts. These volumes will likely most interest scholars researching his biography and contributions to biology. A journal from 1918 includes a mix of typed and handwritten entries documenting a trip to Europe by steamship. Finally, the last two volumes might very well have been co-authored by both Raymond and Maud Dewitt Pearl. The first, a loosely bound journal bearing the dates "1924, 1927" appears to have been maintained by both Pearls. The second, dated 1928, appears to have been kept by Maud, especially given all of the third-person references to Raymond Pearl ("R.P."). Both "1924, 1927" and "1928" recount travels in England, France, and, to a lesser extent, Germany. These diaries, while quite limited in nature, may interest scholars researching Europe in the early-twentieth century, biology, and the history of science more broadly.
 

Contained in a single volume spanning 6/8/1845-9/30/1858, C.J. Varley astronomical observations include telescopic data on comets, stars, and planets. Of particular note are the detailed ink and watercolor sketches that accompany many of the observations. Scholars researching nineteenth-century astronomy, particularly the study of Mars, Jupiter, Saturn, and the Transit of Mercury, will find this volume of particular interest.
 

The first journal, entitled, "Exchange Book A 1833," includes notes on minerals, individuals, and destinations spanning 6/15/1833-4/7/1843.
 
Jackson maintained two sequential volumes between 1840 and 1841. The 1840 notebook contains entries written between 9/21-10/6, and devotes significant attention to non-geological affairs, such as towns and people, husbandry, farming methods, and yields for oats, potatoes, wheat, and various dairy products. The 1841 volume is considerably more focused on geology, with detailed accounts of granite, smoky quartz, limestone, iron, marble, and lead mines and quarries across New England. While these entries are almost single-mindedly focused on geology, there are instances when Jackson considers other affairs. For example, between 7/4-7/9, he briefly acknowledges the illness, death, and funeral of his daughter, Susan
 
on 7/20, he notes a "late speculation mania
 
" and shortly after an 8/17 entry, he describes a visit to Quebec with some commentary on the Lower Canada Rebellion. This journal features numerous hand-drawn diagrams, many of which are noteworthy for their excellent draftsmanship (8/15 and 9/15).
 
An 1849 journal continues in much the same vein, detailing geological discoveries, carefully rendered diagrams (e.g. 8/4), and barometric readings.
 
Jackson also maintained an account book that spans January 1855-October 1857. That volume features a letter to a "Humphrey Esq.," dated 1/6/186[sic] and a signed entry concerning a dispute regarding certified copies of a document, dated 8/21 (presumably 1857). Interested researchers may choose to review other notebooks in the Geology Journals box, such as a catalog of rocks and minerals from Lake Superior and a scrapbook maintained by Mrs. C.J. Jackson, dated 1881.

Charles Thomas Jackson maintained at least five notebooks that could be classified as diaries, which detail geological expeditions undertaken between 1833-1849. These diaries may interest researchers considering Jackson's geological surveys, New England farming, husbandry, and geology, and the Lower Canada Rebellion.

Edmund Beecher Wilson maintained a private journal than traverses much his tenure at Columbia University (12/5/1903-5/24/1928). Wilson includes frank assessments of undergraduate and graduate students, many of whom would become leaders in the fields of biology, genetics, and zoology. For example, he writes of Rebecca Lancefield—who would become a leading microbiologist—"good on the whole, faulty in spots" (5/26/1917). Other prominent graduate students include A. Franklin Shull, Jack Schultz, Hermann Muller, Calvin Bridges, Alfred Sturtevant, and Curt Stern (for whom APS possesses two diaries). Researchers interested in the history of science, education, and the research university will find this volume particularly useful.
 

Roughton's notebooks are scattered across eight boxes. Diaries include a 1927 reading/research diary
 
12 appointment diaries maintained between 1928-35, 1954-55, 1962-65
 
and 25 lab notebooks spanning 1940-66 (with exception of 1947-8 and 1954).
 
The research diary includes reading notes as well as formulas, illustrations, and notes related to experiments and lectures.
 
Appointment diaries include sketches and doodles, account balances, breakfast and dinner plans, to-do lists, reading lists, meetings, lectures, and various ephemera. While entries focus on his research and career, Roughton sometimes intersperses personal notes, such as family visits (8/9/1929), vacation plans (3/13/1931), and social outings (12/13/1933). An appointment diary for 1965 tracks his finances between 1947-1972.
 
The laboratory notebooks stretch the definition of diary, and many—not included here—lacking complete dates or years. In addition to notes related to experiments, meetings, and lectures, the laboratory notebooks often include various ephemera such as loose pages of notes, illustrations, and conference programs. For some years, Roughton maintains multiple notebooks. For example, there are at least three books related to 1951 scattered across folders in box 110 and 111. Researchers will find at least an additional 1953 notebook in a "Misc. Undated Folder" in box 116. The 25 books identified in this note include only dated laboratory notebooks
 
researchers interested in Roughton's research would be well-advised to review all laboratory notebooks available in boxes 109-116.

In 38 notebooks that span his career at Cambridge and beyond (1927-66), Francis Roughton records voluminous notes related to his research, meetings, experiments, and finances. These volumes may interest researchers examining Roughton's career and the field of respiratory physiology more generally.

This collection contains at least 18 diaries spanning more than thirty-five years (1917-1954) of unusual diaries available as both loose pages (contained in 5 folders) and traditional notebooks (11 bound volumes). Maintained by crystallographer Rose Mooney-Slater, these records offer insights into her graduate education at Tulane University and the University of Chicago, Guggenheim Fellowship in Europe on the eve of World War II, and noteworthy career during the postwar period. Alongside many rich ancillary materials--such as a Friendship Book with numerous photographs from 1914-17--Mooney-Slater's diaries provide detailed information about her personal and professional life. Of particular note is a diary describing her aborted Guggenheim Fellowship in Holland at the outset of World War II, as excerpted in Selected Quotations (9/1/1939). With the outbreak of war, Mooney-Slater cuts short her fellowship and books passage back to the United States as others rush to leave Europe. Early diaries provide glimpses into her struggles to balance marriage with graduate education (1928-29) and later diaries document her wide-ranging professional travels during the postwar period, including trips to Europe in both 1951 and 1954. Unfortunately, many of these volumes are water-damaged, and it can be challenging to trace the chronology of materials in folders (particular items in the 1917-1952 folder). However, scholars willing to take the time to peruse these records will be richly rewarded with insights into twentieth-century science, the postwar research university, and the inner life of a remarkable female scientist.
 

David Shinn Collection of Mary Christiana Sellers contains at least 14 diaries spanning nearly a century (1834-1923) and three generations of the Sellers family: Samuel W. Sellers, Jennie P. Sellers and Jennie Haines. Samuel Sellers, who served as justice of the peace in Chester County, furnishes the earliest and longest range of diaries (1834-1881). He maintained journals (most of which are unbound) between 3/1/1834-6/21/1851, 6/15/1851-8/17/1855 (as well as a separate volume for 8/18-11/14/1855), January 1857-October 1858, 11/12/1855-1/31/1875, and 1/3/1878-3/2/1881. Overall, his entries are short, though they record weather, births, deaths, local affairs, some transactions and accounts, and some national news. For example, he commemorates the death of President Polk (6/22/1849) and notes, with some disapproval, an anti-slavery meeting in West Chester staged shortly after the passage of the Compromise of 1850, excerpted in Selected Quotations (10/23/1850). His daughter, Jennie Sellers furnishes two of the most animated journals, particularly for scholars interested in Confederate sympathy in the U.S. North. In her diary from 1860, Jennie, then 16 years old, expresses some disgust with the recently elected president, Abraham Lincoln (March 1860). In her second diary, which traverses the end of the war (1/1/1864-3/20/1866), she records the surrender of General Lee (4/10/1865) assassination of Lincoln (4/15/1865), and funerial procession in Philadelphia (4/16/1865). Perhaps most remarkably, she includes an extended screed against Abraham Lincoln and in defense of John Wilkes Booth, which she may have copied from a local newspaper. That passage is excerpted at length in Selected Quotations. Finally, Jennie Seller's daughter, Jennie Haines furnishes six daybooks from 1887, 1898, 1901, 1904, 1908, and 1923. Maintained in Centennial, Standard, and Daily Reminder diaries, these bound volumes detail the weather, household chores (such as churning butter), visits to the market (often with grocery prices), and miscellaneous accounts. Some of the volumes include various ephemera in the back pockets. Although Jennie Haines rarely discusses national news, she does include at least one oblique reference to the Spanish-American War when she discusses the loss of the Battleship Maine (2/19/1898).
 

As described in greater detail in the Early American History note, Hutchinson discusses a host of troubles aboard his ship. Those include concerns about lightning strikes to the ship laden with gun powder (2/26), various issues with bread and meat rations (2/28), and a brief encounter with a French brig that Hutchinson describes as "in almost as bad a situation as ourselves, but able to spare several bottles of spirits and roughly two pounds of cheese" (3/3). Upon reaching landfall in Chesapeake Bay (3/9), Hutchinson devotes the remaining entries his journey back to Philadelphia. At the back of the volume, he encloses an essay defending Quakers against chargers of loyalism, for which a rough transcription is provided below.

This incomplete volume describes the culmination of a transatlantic journey taken by James Hutchinson in the winter of 1777 (2/26-3/16). Having completed his medical residency under the supervision under Dr. John Fothergill at St. Bartholomew's Hospital in London, Hutchinson describes in detail his journey back to Philadelphia, where he would serve as Surgeon General of Pennsylvania. In addition to offering an account of what Hutchison terms a "very disagreeable" transatlantic voyage, this volume includes an essay defending Quakers from attacks by revolutionaries, which might have been intended for publication. (The essay is signed "A Friend to the Liberty of Conscience.") This volume may interest researchers exploring the eighteenth century Atlantic, seafaring, and the Society of Friends in the American Revolution.

Haas opens her diary with an agenda to maintain a record of readings—and quotations pulled from those readings—as well as her own aspirations. In most entries, she responds to—and often argues with—arguments that she pulls from her diverse reading, which traverses Alcott, Balzac, Beowulf, the Bronte sisters, Dewey, Freud, Gorky, Hardy, Ibsen, Nietzsche, Thackeray, Tolstoy, and Voltaire.
 
For example, in one early entry, she takes Tolstoy to task, writing, "Some kinds of music may dull the mind, but I do not believe that all music dulls the mind. Besides, even music that dulls the mind has its place" (7/15/1928). Often, she uses those theories to rationalize her own artistic process: "Since I have studied psychology, I do not believe that artistic creation is a result of divine inspiration. My hypothesis is that these themes, which seem to be a result of divine inspiration, come in reality from my subconscious mind" (7/30/1928). Elsewhere, she advocates for limits of reason and value of emotions (e.g. 7/29/1928, 7/30/1928, and 11/25/1928).
 
While Haas largely abstains from discussing personal affairs in her correspondence, she includes several diary entries that chronicle her experiences with dating and romance (e.g. 12/2/1928 and 12/7/1930)
 
as one of her New Year's resolutions, she even adds the note: "Should not marry for at least three years" (12/1929). (Curiously, in that entry she also anticipates marrying three times.) Finally, although she mostly focuses on literature and music, Haas also includes several prescient notes on geopolitics, including the role of America in the world (e.g. 7/21/1928 and 8/2/1928) and the ebb of British colonialism (e.g. 8/7/1928).
 
Her diary concludes on 1/3/1931, with Haas enrolled at the University of Chicago, where, despite a full course roster, she plans a supplemental study regimen to guard against over-specialization: "I have planned a course of study for myself, which if carried out, will be more comprehensive than any university education could possibly be unless supplemented by wide reading."

In a diary that spans 1828-31, researchers receive an inside glimpse into Haas's early thinking about art, literature, dating and relationships, and even, to some degree, early-twentieth-century geopolitics. This diary ought to interest researchers interested in the arts, colonialism, psychology, and women's history.

The Harlan journals recount two of three overseas voyages he took in his career. The first documents a trip to India that he made as a medical student in 1816-1817. This volume offers detailed accounts of the sea voyage (with some locational coordinates and accounts of weather) and accounts of Indian towns and cities, including Calcutta (3/9/1817). Alongside descriptions of Indian hospitals (e.g. 3/21/1817) and botanical gardens (3/23/1817), Harlan also writes at length about the indigenous peoples, including their shrines (4/10/1817), burial rights (6/17/1817), and what he considers their "lamentable" need for Christianity influence (4/11/1817). Harlan's accounts often feature an uncommon sense of voice, inflected with a deep colonialist bias. For example, in one of his later entries, he describes India as a place of fanaticism, war, and declension: "But India, once the seat of Literature and Science, hath at length dwindled into the most inordinate fanaticism, which binds the inhabitants in the grossest ignorance…since the year 1000, India has presented nothing but war and bloodshed. Her cities reduced to ashes, her fields laid waste by hosts of conquering armies, having been successfully overrun by the Mahomedan Princes" (6/17/1817).
 
Harlan's second journal finds him at the apogee of his career as a physician and scientist. Seeking to advance his scientific reputation among his peers, Harlan took a tour of Europe in 1833, extending his professional network of naturalists and medical researchers in the continent's cultural and economic capitals. In addition to visits to the northern European metropolises of Liverpool, London, Cambridge, Dublin, and Paris, he travels south to Bologna and even ascends Mount Vesuvius (9/26/1833). Notably, before he returns to New York, Harlan attends at least one meeting of the Phrenological Society in London (10/29/1833) and participates in a debate about U.S. slavery (6/21/1833), excerpted in Selected Quotations.

A pair of travel journals maintained by Richard Harlan, a prominent Philadelphia-based scientist and doctor, offer insights into India in the early-nineteenth century and European medicine in the antebellum period. The first journal (1816-17) recounts Harlan's went to India as ship's surgeon of the East India Company. Entries include Harlan's extensive reflections upon—and judgements of—indigenous peoples' customs, burial rights, and religious practices. The second volume (1833) documents a trip Harlan takes to Europe at the apex of his career. That journal offers a window in antebellum medical practices in Europe, including the field of phrenology and Harlan's justification for U.S. slavery. Both volumes are remarkable for their detail and sense of voice, and they will certainly interest scholars researching British colonialism in India, European medical science, and slavery in the antebellum United States.
 
The Harlan journals recount two of three overseas voyages he took in his career. The first documents a trip to India that he made as a medical student in 1816-1817. This volume offers detailed accounts of the sea voyage (with some locational coordinates and accounts of weather) and accounts of Indian towns and cities, including Calcutta (3/9/1817). Alongside descriptions of Indian hospitals (e.g. 3/21/1817) and botanical gardens (3/23/1817), Harlan also writes at length about the indigenous peoples, including their shrines (4/10/1817), burial rights (6/17/1817), and what he considers their "lamentable" need for Christianity influence (4/11/1817). Harlan's accounts often feature an uncommon sense of voice, inflected with a deep colonialist bias. For example, in one of his later entries, he describes India as a place of fanaticism, war, and declension: "But India, once the seat of Literature and Science, hath at length dwindled into the most inordinate fanaticism, which binds the inhabitants in the grossest ignorance…since the year 1000, India has presented nothing but war and bloodshed. Her cities reduced to ashes, her fields laid waste by hosts of conquering armies, having been successfully overrun by the Mahomedan Princes" (6/17/1817).
 
Harlan's second journal finds him at the apogee of his career as a physician and scientist. Seeking to advance his scientific reputation among his peers, Harlan took a tour of Europe in 1833, extending his professional network of naturalists and medical researchers in the continent's cultural and economic capitals. In addition to visits to the northern European metropolises of Liverpool, London, Cambridge, Dublin, and Paris, he travels south to Bologna and even ascends Mount Vesuvius (9/26/1833). Notably, before he returns to New York, Harlan attends at least one meeting of the Phrenological Society in London (10/29/1833) and participates in a debate about U.S. slavery (6/21/1833), excerpted in Selected Quotations.

Chemist and mineralogist Thomas P. Smith maintained a five-volume journal during a tour through Europe between 1800-1802. Elected to the American Philosophical Society in 1799, Smith bequeathed his journal to the APS with the request that it be published if found to contain information "useful to the manufactories of my country." Although his observations tend to concentrate on European technological improvements in manufacturing and mining (sometimes with rough diagrams), these volumes also document his travels across Europe and comments on European society and culture. Of particular note may be his accounts of Luxemburg (7/14/1800), Hamburg (7/15/1800), and Stockholm (8/22/1800), excerpted in Selected Quotations. Notably, the third volume features a "Resume du Cours del Mineralogie," written in French and English. The Thomas P. Smith journal may interest scholars researching Europe at the turn of the nineteenth century, Smith's career in mineralogy, as well as the institutional history of American Philosophical Society.
 

Contrary to its title, "Sigma Xi lecture tour, 1953" includes entries between 10/14-11/22/1952, shortly after his election to the American Philosophical Society. Contained in a Spiral Stenographer's Notebook (with loose pages until the 11/12 entry), this notebook provides a granular account—often down to the hour—of his travels, meetings, lectures, and seminars with specifics accounts of people, places, and universities. Notably, Stern regularly evaluates audience attendance and engagement, and names individuals with institutional affiliations. Occasionally, he judges institutional priorities. For example, of LSU he writes, "Big campus: Spanish moss and architecture. Money assigned to enlarging stadium instead of library" (10/15/1952). And, while he tends to focus on higher education, occasionally, surrounding communities permeate his observations. For example, in his LSU entry, Stern also records segregation, adding, "road past unpainted negro houses--very small, no basement" (10/15/1952).
 
A second, unbound volume from a decade later provides a detailed account of a two-week trip to the Soviet Union. Maintained between 5/13-6/2/1963, "U.S.S.R Exchange Visit" documents Stern's travels, meetings, seminars, and sightseeing. Although most of the entries are dedicated to his genetics research, Stern also notes visits to various cultural sites and landmarks, including: the Kremlin, in whose mausoleum he writes "Lenin's face yellowish as for wax with light making it glow from inside" (5/16/1963)
 
Sverdlovsk Square, which he describes as "early-19th century Versailles-like park and castle," (5/16/1963), and the Ruski Museum, in which he describes Soviet realism as "wheat factories, sturdy healthy people, statue of men [forging] sword into plough" (5/29/1963). Stern includes at least one brief account of religious practice (or lack thereof) in 1960s Soviet Union, writing: "Morning visit to the churches in the Kremlin…They are all museums but kept in the spirit of religious places. No atheistic propaganda" (5/25/1963).

Curt Stern Papers include two diaries written after his inauguration into the American Philosophical Society and move to UC Berkeley. The first documents a national lecture tour taken in the fall of 1952 and the second, from the spring of 1963, describe an exchange visit to the Soviet Union. Read in tandem, these two volumes may interest researchers investigating Stern's work in genetics and his scholarly networks, segregation and the Jim Crow South, the post-war research university, and the Soviet Union in the Cold War.

Bache's diary provides curt but consistent accounts of the Union's military operations, particularly along the Mississippi River. Those include the Battle of Charlotte (4/25), the Battle of Baton Rouge (5/28), and the Battle of Vicksburg (6/28). Notably, Bache travels to shore on at least one occasion, furnishing first-hand accounts of the Confederate South. For example, he attends a religious service, writing, "Some of the officers went to church where they prayed for the President of the Confed. States" (5/13). Later, he describes as Natchez as a "very pretty place" (5/18). Interested researchers might consider pairing this volume with the Thomas Hewson Bache Diary, also from 1862, which provides a surgeon's perspective on the Battle of Baton Rouge.

The Alexander Dallas Bache diary offers an unusual view of Civil War battlefields from the perspective of the superintendent of the United States Coast Survey. Bache served as Captain's Clerk aboard USS Harford flagship, one of 17 Union ships that traveled up the Mississippi River to take New Orleans. With entries spanning the spring and summer of 1862 (4/14-7/13), this volume recounts naval bombardments in the early years of the war, provides textured accounts of the Confederate South, and will no doubt interest researchers who study the Civil War, U.S. military history, and the Confederate States of America.

Interested researchers would do well to consult the detailed description of Hunter's four volumes available in the Early American History Note. For the purposes of diary researchers, the first volume (1796) warrants attention for its descriptions of indigenous peoples and early settlements. For example, Hunter offers an extended account of St. Louis (9/4/1796). He also describes an Indian woman whose nose was cut off by her husband for infidelity, a passage excerpted in Selected Quotations (9/9/1796). The 1802 journal documents Hunter's trip across Pennsylvania (Berlin, Carlisle, and Shippensburg), visit to a cave in Kentucky, and discussion of salt production at Blue Lick. Finally, the last two journals (1804, 1809) include various travels in the South, including a description of expedition to the Hot Springs of Arkansas (1804-1805) as well as longitudes and latitudes that researchers might use to trace Hunter's journey. Notably, Hunter discovers Mammoth bones, which he compares to those of Charles Wilson Peale, writing, "I cannot for bear mentioning a great natural curiosity I have just seen here [sic] about 2 ½ Tons of Bones of one or two Mammoths twice as large as Peals" (5/27/1804).

George Hunter maintained four journals during expeditions into Kentucky, Illinois, Mississippi, and Louisiana between 1796-1809. Hunter records his daily affairs, observations of territories, visits to trading centers, and commentary on international rivalries and relations with various indigenous peoples, including the Delaware, Cherokee, Chickasaw, Choctaw, and Osage. With rich, narrative accounts of western travel in the early national period—including exploration of Louisiana shortly after the Louisiana Purchase—the Hunter diaries ought to interest scholars researching the American west, Native America, and U.S. empire.
