The Zaccheus Brown notebook contains information compiled between 1782 and 1783 on arithmetic, sailing and navigation, and surveying, as well as a log of the Phoenix's voyage from New Jersey to the Virgin Islands in 1789. Mathematical and navigational problems are often illustrated with diagrams, and the volume also contains an example of a Mercator chart of the Caribbean.

The Zaccheus Brown notebook (175 pages) contains information on arithmetic, sailing and navigation, and surveying, as well as a log of the Phoenix's voyage from New Jersey to the Virgin Islands in 1789.

The first 112 pages, compiled from 1782-1783, are comprised of information about mathematics and sailing and contain a brief ship's log. Mathematical subjects include square and cube roots, geometry, and plane trigonometry; Brown copied and solved mathematical problems, which are often illustrated with diagrams. Instructions for aiming cannons appear in the section about trigonometry. Brown also described sailing methods such as plane, traverse, oblique, Mercator, parallel, middle latitude, and current sailing, as well writing instructions for turning a ship windward and for determining location. The parts of the volume concerning sailing also contain problems, diagrams, and an example of a "Plane Chart" and "Mercator's Chart." The Mercator's chart shows the locations of islands in the northern Caribbean Sea. The notebook's other subjects include the compass, calculating the phases of the Moon, and the Gregorian calendar. A final section pertains to surveying.

Zaccheus Brown's notebook also contains logs concerning the voyage of the Endeavour (9 pages) and the schooner Phoenix (58 pages). The Endeavour log, attributed to "L. H," notes the ship's journey "from the Cape" in late June and early July 1783. The Phoenix log details Brown's voyage from June 17, 1789-September 1, 1789 from Salem, New Jersey, to the Virgin Islands and back to Virginia. Some of Brown's daily entries about his voyage on the Phoenix include charts recording the ship's course and position, along with additional remarks on wind speed and direction. Brown occasionally discussed other aspects of his voyage, such as the pidgin language spoken by the ship's Dutch crew and his premonitions after bad weather and delays. He also described the port and the island of Saint Thomas, a Dutch colony (currently part of the United States Virgin Islands).

The volume contains illustrations of a man in the sun, a compass rose, and a fish and man; the latter drawings are flourishes on the heading for the section of the book on cube roots. The back endpaper includes a table of angles related to navigation.

This volume contains 44 pages of signals and roughly 46 pages of instructions and explanatory information pertaining to the Royal Navy's operations under Richard Howe around the time of the American Revolution. The book provides details about signals to be used while sailing by day, in fog, in battle, and at night, and it includes color illustrations of signal flags and lantern configurations. The binder's title is "Ld Howes Instructions."

This log book pertains to the voyage of the bark Neptune from Philadelphia, Pennsylvania, to Mauritius and back to Philadelphia between May 1789 and August 1790, as well as multiple voyages of the schooner Federal between Pennsylvania and the Caribbean between March 1791 and November 1791.

This log book (around 200 pages) pertains to the voyages of the bark Neptune from Philadelphia, Pennsylvania, to the Isle of France (present-day Mauritius) and back to Philadelphia from 1789-1790 and voyages of the schooner Federal between Pennsylvania and the Caribbean in 1791. The log entries are written in a pre-printed The Seamen's Journal Book (London, 1785), with sections for each day's measurements and remarks.

The log entries from the voyages of the Neptune (which comprise the bulk of the volume) and the Federal are typically notes on the wind direction, ships' courses, and ships' positions. Additional prose remarks concern weather conditions, the sighting of land, encounters with other ships, and anchorage at a port or harbor. The log has gaps during the Neptune's stay at the Isle of France and during the Federal's time in Caribbean and United States ports.

The first page of the volume, preceding the printed title page, has calculations involving an epact. The book's final pages contain entries from one of the Federal's voyages and additional notes about the Neptune's time at the Isle of France in December 1789 (particularly regarding a thunderstorm). A sheet of paper laid into the book contains notes about an unknown vessel's anchorage at Saint Helena in May and December 1783.

This 93-page journal and account book chronicles a year in the life of Nehemiah S. Hayden, a sailor and shipbuilder from Essex, Connecticut, including voyages aboard the John H. Elliott to Antwerp, Belgium, and the clipper ship Frederick Gebhard to Savannah, Georgia. On 80 pages of journal entries, Hayden recounted the weather, shipboard tasks, and movement of other vessels, and offered brief glimpses of his personal life on and off ship. Five scattered pages of accounts entries detail Hayden's expenses for clothing, sundries, and services for 1858. Completing the volume is an anonymous 8-page work of prose (including the date January 15, 1858), telling the story of a young woman's heartbreak over the loss of her sailor love and his return to her after his rescue by an English ship. The front and back pastedowns bear sketches of a three-masted, square rigged ship (apparently the Frederick Gebhard) and a two-masted, gaff rigged vessel.

This 93-page journal and account book chronicles a year in the life of Nehemiah S. Hayden, a sailor and shipbuilder from Essex, Connecticut, including voyages aboard the John H. Elliott to Antwerp, Belgium, and the clipper ship Frederick Gebhard to Savannah, Georgia.

The journal portion (80 pages) dates from January 1 to December 6, 1858, and documents Hayden's life in Essex, Connecticut, onboard the sailing vessel John H. Elliott, and while docked in Antwerp, Belgium. Notations of daily weather, particularly the wind, are prominent throughout. While in Essex, Hayden noted visits with friends and family (including a young woman nicknamed "Chick"), mail sent and received, and church services attended. He went clamming, duck hunting, and sailing near home, and he committed himself to a yearlong temperance pledge. At sea, he chronicled daily tasks, encounters with other ships, and the logistics of sailing operations. While in port, he took walks with crewmembers, sent mail, and completed numerous painting and construction projects (including installation of passenger berths) on the ship. He went sightseeing in Brussels for a day. His ship set sail in July for a return voyage by way of Dover.

The December 1858 entries describe Hayden's time in Savannah, Georgia, while aboard the ship Frederick Gebhard (which he joined in October 1858). Several members of the crew (including several black men) took an excursion into town one day and went oyster gathering another. Before setting sail, the ship took on a number of men including "a large bear," who later got into a fight with "Turk."

Five scattered pages of accounts entries detail Hayden's expenses for clothing, sundries, and services for 1858.

This collection is made up of 2 volumes that Marianna Chandler Lanman composed while studying at Mrs. Rowson's Academy for Young Ladies in Boston, Massachusetts, around 1814. One concerns arithmetic, focusing on practical applications in bookkeeping, conversion, and monetary transactions; the other contains copied poems, calligraphic alphabets, and graphic illustrations.

This collection is made up of 2 volumes that Marianna Chandler Lanman composed while studying at Mrs. Rowson's Academy for Young Ladies in Boston, Massachusetts, around 1814. One concerns arithmetic, focusing on practical applications in bookkeeping, conversion, and monetary transactions; the other contains copied poems, calligraphic alphabets, and graphic illustrations. Lanman dedicated both volumes to her parents.

Lanman composed the first volume, entitled "Practical Arithmetic[:] Comprising All the Rules for Transacting Business" (10"x16", 60 pages), at Mrs. Rawson's Academy in 1814. Its sections, each labeled in calligraphy, concern mathematical operations, rules and theorems; weights and measures; and practical applications of mathematical principles. Many of the later pages concern subjects such as the calculation of simple and compound interest, the value of "federal money" against "lawful money" (state currencies), commission charges, and bookkeeping. The explanatory text is accompanied by finished exercises and problems. The volume also includes tables of weights and measures and an index.

The second volume, "Specimens of Penmanship" (16"x10", 23 pages), is undated. Lanman copied poetry and proverbs on the book's odd-numbered pages; most concern subjects such as happiness, rural living, and gratitude. The title of a poem on the "Pleasures of retired Life" is written on a drawing of a ribbon (p. 19). One poem, entitled "Virtue's Tears Embalm the Brave," is dedicated to the memory of American casualties of the War of 1812 (p. 21). The volume contains several drawings: a hermit in his home (p. 3), a bald eagle among patriotic decorations (p. 21), a sailing ship (p. 21), and a line drawing of a bird with the word "industry" in its feathers (p. 23). The volume also includes examples of cursive, German, and Old English alphabets.

This volume contains an anonymous journal of a voyage from Kennebunk, Maine, to New Orleans, Louisiana, and Cincinnati, Ohio, between December 9, 1852, and January 24, 1853, as well as poetry, short stories, and essays composed by a second unknown writer between May 1857 and February 1887. One poem and one story concern the Civil War, and the author composed biographical essays about prominent individuals, families, and other topics.

This volume contains an anonymous journal of a voyage from Kennebunk, Maine, to New Orleans, Louisiana, and Cincinnati, Ohio, between December 9, 1852, and January 24, 1853 (21 pages), as well as poetry, short stories, and essays composed by a second unknown writer between May 1857 and February 1887 (117 pages). One poem and one story concern the Civil War, and the author frequently composed biographical essays about prominent individuals, families, and other topics.

The first 21 pages, titled "Journal of a voyage from Kennebunk to New Orleans," are made up of daily diary entries composed during a voyage from Maine to Louisiana and from Louisiana to Ohio. The author embarked from Kennebunk, Maine, onboard the Golden Eagle (commanded by Captain Nathaniel Thompson) on December 9, 1852, and made daily observations about life at sea. As the Golden Eagle approached Florida in late December, he described the scenery in the Bahamas, the Florida Keys, and coastal Louisiana. On one occasion, the ship encountered a boat transporting slaves to New Orleans. The author arrived in New Orleans on December 28, where he wrote about some of his experiences in the city, such as a visit to the cattle market. On January 12, he boarded the steamer Yorktown for a journey up the Mississippi and Ohio Rivers to Cincinnati. He noted the cities passed along the way, such as Vicksburg and Memphis, and described southern plantations, making note of their use of slave labor. On January 15, he reported that the Yorktown had taken a newly purchased African American family onboard, who entertained the passengers with dancing and music. By the final entry, dated January 24, 1853, the author had just passed Evansville, Indiana.

The volume also contains a commonplace book, in which the writer composed 117 pages of poetry, short stories, and essay. Several poems are translations of German poems by Johann Wolfgang von Goethe and Ludwig Uhland, and others appear to be original compositions. Among the latter is "Our Native Land," a patriotic verse written in March 1863, and additional poetry dated June 1869. The author wrote one short story in March 1862. An essay, "the Presentiment," consists of recollections of a war-era soldiers' relief society worker and a story respecting a woman's premonition of her own death. Biographical sketches and essays comprise most of the remaining material and are often annotated with small edits. Persons of interest include Horace Walpole, William Cowper, Nassau family members, Michael Faraday, Sir Philip Sidney, Norman Macleod, Dr. John Brown, and Henry of Navarre. Other essays concern the "Besor brook" in Judaea, the rivers of Babylon, and the telegraph.

A financial account between Charles Thompson and Nathaniel L. Thompson, settled in Kennebunk, Maine, on January 1, 1856, is laid into the volume.

This journal recounts Joseph E. Taylor's experiences onboard the Andrew Jackson during a voyage from Philadelphia, Pennsylvania, to Bremen, Germany, in September 1876. Taylor illustrated his journal with pictures of the ship's sails and interior.

This journal (35 pages) recounts Joseph E. Taylor's experiences onboard the Andrew Jackson during a voyage from Philadelphia, Pennsylvania, to Bremen, Germany, in the fall of 1876. Under the command of J. C. Bartlett, the ship left Philadelphia on September 3, 1876. The Andrew Jackson reached the English Channel on September 25 and approached Germany in early October, as Taylor composed his final journal entry. Taylor described the voyage, including events such as bird and porpoise sightings, and made notes about the Gulf Stream. The journal also includes several sketches of the ship's interior (pp. 1, 3-4), accompanied by detailed descriptions. A small printed map laid into the volume shows the "Saloon and Cabin Plan of the American Steam Ship Co.'s Steam Ships 'Pennsylvania,' 'Ohio,' 'Indiana,' 'Illinois.'"

Elements of Navigation, a manuscript adaptation of John Robertson’s work of the same name, provides instruction and practical exercises in arithmetic, geometry, trigonometry, geography, astronomy, and navigational principles (781 pages). The volume is heavily illustrated with mathematical diagrams. It also contains a 1785 copy of a ship log for a 1772 voyage from England to Madeira, (21 pages).

"Elements of Navigation," a manuscript adaptation of John Robertson’s work of the same name, provides instruction and practical exercises in arithmetic, geometry, trigonometry, geography, astronomy, and navigational principles (781 pages). The volume is illustrated with mathematical diagrams. It also contains a 1785 copy of a ship's log for a 1772 voyage from England to Madeira (21 pages). The book is divided into 14 primary chapters, 11 of them preceded by an ink or watercolor illustration of buildings, ships, and places, such as the watercolor drawings "The Desire in a Storm" and "A west View of Islington, old Church." (See below for complete list.) Several chapters are further divided into sections, and most chapters or sections are followed by problems, questions, case studies, answers, and explanations. Please see the box and folder listing below for a table of contents.

The volume begins with explanations of basic mathematical principles, including arithmetic operations, decimals and fractions, roots and powers, notation, and "Tables of English Money, Weights, and Measures" (pp. 9 verso-10 verso). This chapter is followed by theorems and problems of geometry and trigonometry. The subsequent section on geography contains prose explanations of the discipline's foundations, such as the shape of the Earth, the concept of latitude and longitude, and the currently known world. Remarks on the continents are accompanied by tables showing major countries, principal cities, rivers, and mountains. The tables for North and South America are split, and individual states within the United States are identified as "countries," as are California, New Mexico, Old Mexico, Louisiana, Canada, New Britain, New Wales, and others. Introductory geographic material also includes content on winds, tides, and bodies of water. A segment on "chronology" introduces several scales for measuring time, and explains the reasoning behind concepts such as the leap year and the "Golden Number" (pp. 147-147 verso).

The remainder of the work focuses on the art of maritime navigation. Several topics include: the calculation of compound courses, oblique and windward sailing, sailing in currents, and globular sailing. The sections devoted to each topic are comprised primarily of rules or theorems, exercises, and illustrations of practical applicability. A chapter on "spherics" introduces spherical geometry and trigonometry. Two chapters on astronomy explain concepts in "star astronomy," "terrestrial astronomy," and "spherical astronomy," such as the composition of the Solar System, planetary movements, and mathematical applications. The final 80 pages contain information on the art of sailing and expand on principles previously discussed. These pages include instructions on how to calculate the location of a ship at sea, make necessary observations, and correct a ship's course, among other similar topics.

The final 21 pages consist of a log from an unknown ship traveling from England to Madeira in 1772, transcribed by James West in 1785. Between July 2 and July 11, the log contains notes on the weather, wind direction, and general remarks of occurrences on board as the ship prepared for its journey at Deptford, London. On one occasion, the author mentioned a sailor being disciplined for drunkenness (July 3). Between July 12 and July 28, the log documents the weather, wind direction, ship's location, use of various sails, and other information compiled throughout the course of each day. The ship arrived at Madeira on July 28. The log is followed by a brief note by James West concerning the location of Funchal, Madeira.

The non-mathematical illustrations separating the book's chapters are done in ink or watercolor, and depict rural scenes and sailing ships.

This log book covers the journey of the English 50-gun frigate HMS Glasgow under the command of Captain Henry Duncan between February 1, 1815, and August 28, 1815. The log records daily information on weather, longitude and latitude, distance, and incidents onboard.

This volume, entitled "Log of The Proceedings of H.M.S. Glasgow" (73 pages) chronicles the ship's travels around the Bay of Biscay between February 1 and August 28, 1815. Midshipman James Williamson recorded daily information about the weather, the ship's course, and incidents onboard. The first 3 pages contain a chart of the ship's course, position, and bearings, maintained daily between February 1 and August 5, 1815; the dates April 1-May 24 are not included. Each day of the week is represented by an astrological symbol in a repeating pattern used throughout the entire volume. The longer log entries commence on February 1, 1815, and cover the ship's course, winds, and remarks about events on the ship, such as the arrival and departure of visitors, discipline of sailors, maintenance work, ships encountered, change of course, weather, and other daily occurrences. The Glasgow moored in Plymouth Sound and "Hamoau" between April 1 and May 25, at Plymouth between June 5 and June 9, and at Sheerness and Chatham, England, between August 8 and August 28. A color-coded map showing the progress of the Glasgow between southwest England and the Bay of Biscay is pasted into the volume between the pages covering May 6 through May 24.
