The Practical Mathematics manuscript contains definitions and problems related to algebra, geometry, trigonometry, navigation, and surveying. Many of the problems are accompanied by illustrated figures and/or practical examples.

The Practical Mathematics manuscript contains definitions and problems related to algebra, geometry, trigonometry, navigation, and surveying. These categories are divided into specific applications; the section on algebra deals with topics such as basic algebraic statements, algebraic fractions, simple and quadratic equations, and arithmetical and geometrical progressions. Most of the problems are accompanied by illustrated figures and/or examples of concepts' practical applications. A section concerning globes pertains to both terrestrial and celestial globes, and includes a list of the signs of the zodiac, as well as descriptions of navigational methods, accompanied by a compass rose and charts, including "Mercator's Charts."

The manuscript also explains methods for determining location and time by observing celestial objects, and contains instructions for keeping ships' logs and surveying notes. A section on navigation includes a copied log from the voyage of the Pegasus from England to Barbados (January 31, 1737-March 22, 1737), as well as a map showing the coasts of France and Spain and the islands around Barbados. Some of the surveying problems are illustrated with a sailing ship, a tree, and a turret.

The Joshua Benjamin journal contains notes and navigational logs on the various crews and voyages of the Brigantine Sarah, Brigantine Young Henry, Ship Lufilania, Brigantine Dolphin, Sloop Tryall, Brigantine Sea Flower, Sloop Experiment, Sloop Endeavor, Sloop Abigail, Brigantine Willam & Mary, Brigantine Union, Ship Samuell, Ship John and Cranwell, and the Ship Welcome, all sailing between 1713 and 1734.

The journal has 303 total pages, including the small pages bound together with the volume. Of these, approximately 258 are devoted to ships' logs. The book contains 60 pencil and ink coastal profiles.

The Joshua Benjamin journal contains notes on the various crews of the Brigantine Sarah and Brigantine Young Henry, as well as navigational logs and notes for various voyages of these ships as well as for the Ship Lufilania, Brigantine Dolphin, Sloop Tryall, Brigantine Sea Flower, Sloop Experiment, Sloop Endeavor, Sloop Abigail, Brigantine Willam & Mary, Brigantine Union, ship Samuell, Ship John and Cranwell, and the Ship Welcome, between 1713-1734. These voyages typically begin or end in Boston, bringing cargo to and from various ports along the Eastern Seaboard, Caribbean, and London.

The volume opens with the following inscription:

Joshua Benjamin Book[:] taken on board the Hardie Brilhae a french Ship of About 400 Tuns 32 guns Mounted x175 men in the year 1710[.] I then belonging to Her Majesty Queen Anne[']s Service in Her Ship the Kent of 70 Guns x 440 men[.]

However, none of the book's entries document the voyages of these ships. The first few pages consist of charts for the crew of the Brigantine Sarah and Young Henry with notes on crew names and positions, their wages, and time served on the ship for that voyage. After these entries is a description of a religious service at the Cathedral of San Salvador in Oviedo, Spain, accompanied by an inventory of holy relics housed there (page 9). The inventory claims 21 relics from various saints and religious figures, including one of the 30 pieces of silver received by Judas, 8 thorns from the crown Jesus wore at his crucifixion, and clothes worn by Jesus.

The next set of entries consists of the logs of the various voyages of Benjamin. He keeps track of the ships'; daily longitude and latitude positions, records the day's wind, weather, and sea conditions, and makes brief notes of daily events (setting off, docking, repairs, meeting other ships and sailors, exchanging goods, etc.). In general, the descriptions provide general information on the experiences of eighteenth-century seamen and speak to the ways in which they handled challenges at sea.

Occasionally, Benjamin describes encounters with other ships, which indicate that the crew felt keenly that the waters were dangerous. For example, on December 27, 1733, he mentions that they spotted two sails giving chase. "We feeling they were Enemies prepared to receive them by fitting the vessels for close fight" (p.141). The ships passed without incident. In one of the longer entries of the journal, Benjamin describes the unfortunate fate of the Brigantine Sarah, which on November 1, 1730, struck a rock that severely damaged the ship five leagues from Bermuda. Eventually, all crew abandoned ship and took refuge on a nearby Island. They were rescued by a passing sloop within 4 days and taken to South Carolina.

Many of the entries include rough pencil sketches of coastal profiles, indicating the basic vertical outline of approaching land. In addition to these profiles is a pen drawing of several fish (p.26) and a map of Martha's Vineyard (p.47). This hand-drawn and well labeled map of Martha's Vineyard is one of the earliest known charts of this passage.

These 3 volumes are an English translation of Robert Challe's Journal d'un Voyage fait aux Indes Orientales, which chronicles his journey to India as purser on the French East India Company's ship Ecueil between 1690 and 1691. Challe described scenery, wildlife, and culture in Africa, India, and the Caribbean.

These 3 volumes are an English translation of Robert Challe's Journal d'un Voyage fait aux Indes Orientales, which chronicles his journey to India as purser on the French East India Company's ship Ecueil between 1690 and 1691. The first volume opens with a brief introduction to the work, translated by "[I.?] R." for J. Boulter, a friend of Challe's. The volumes, which cover the entirety of Challe's travels on the Ecueil and contain many revisions and corrections, are accompanied by a two-page letter by Sir David Dundas concerning the manuscript's translation and contents, the background of the author, and the reasons why Dundas does not believe that the Hakluyt Society would be interested in publishing the text. Each of the 3 volumes bears the bookplate of Sir Thomas Baring, Baronet.

Challe began his narrative on February 24, 1690, when six ships under the command of Abraham Du Quesne departed from Port Louis, France, for the East Indies. He recorded his observations in daily entries, which vary in length between single sentences and descriptive passages of 30 pages or more. Challe recorded the ship's course and location, though he noted the unreliability of longitude measurements and remarked on the inaccuracy of contemporary maps (Vol. 1, pp. 67-68). After heading south along the coasts of France and Spain, the Ecueil made stops in the Canary and Cape Verde Islands, and Challe reflected on the history of Spanish conquests in the New World, as well as on predestination and other topics related to Christianity. Challe also described daily events onboard the ship and marine life he observed. The first volume concludes on May 30, 1690, with the ship's arrival at the Cape of Good Hope, which occasioned a discussion of Dutch trade.

The narrative resumed on June 1, 1690, as the Ecueil headed for Madagascar; the second volume includes a lengthy essay on the history, people, flora, and other aspects of the island of Moaly (Mohilla/Mwali) (pp. 30-63). The volume also contains a description of the ship's encounter with the British Philip Herbert, which ended when the trapped British captain set his own boat on fire, resulting in the death of most of his crew (Vol. 2, pp. 64-76). Challe composed entries as he traveled around the Maldives and Ceylon, and temporarily ceased writing after his arrival in Pontincheri (Pondicherry), India, on August 12, 1790. His next entry, dated August 24, 1690 (Vol. 2, pp. 116-158), describes the area, including observations on local slaves (Vol. 2, p. 137). After traveling along the eastern coast of India and down the western coast of Burma, the ship sailed to Bengal, where it remained at the close of Volume 2 on December 31, 1690. Volume 3 opens on January 1, 1691, shortly before the Ecueil began its return journey to France, a voyage covered in daily entries that often concern the wind speed and the author's increasing boredom. The Ecueil traced its earlier route around the Cape of Good Hope before crossing the Atlantic Ocean for a journey to Martinique and other Caribbean islands. After leaving the Americas on July 9, 1691, the Ecueil returned to Port Louis on August 20, the final date recorded in the journal.

This log book contains daily reports for a French ship, commanded by M. de Breuille, that sailed between the Caribbean and Europe, and around the Mediterranean in the 1730s.

This log book contains daily reports for a French ship that sailed between the Caribbean and Europe, and around the Mediterranean in the 1730s. The book is preceded by the following statement: "Au nom de dieu soit fait a journal teneu par le St. francois pied noir..."

The bulk of the volume, around 400 pages, consists of daily log entries for voyages between April 1731 and January 1737, written by St. François, "pied noir" [black foot]. Most entries include reports on the weather, winds, and the ship's position. The ship called at Cadiz, Marseille, and St. Malo, among other ports.

The final pages are comprised of additional notes and instructions, such as a list of items sold in Cadiz, an illustrated method for calculating a building's height, and instructions for melting metal and producing gunpowder. An ink drawing of a flower appears on an early page. The volume contains the bookplate of Robert R. Dearden.

The collection focuses primarily on John Tailyour, a Scottish merchant who traveled to North America and Jamaica in the 1770s and 1780s to conduct business, before finally returning to his home in Scotland in 1792. His correspondence is heavily business related, centering especially on his trading of slaves, foodstuffs, and sundry goods. It also chronicles the current events in both Jamaica and the Empire. Many of Tailyour's correspondents debate the meaning and merit of the cessation of the slave trade in the late 18th century, as well as the military events of the American and Haitian revolutions, and of the Maroon rebellion of 1795. The papers also include letters between John and his family in Scotland regarding John's mixed-race Jamaican children. He sent three of his children to Britain to be educated, which caused much family concern. Tailyour's account books and financial papers relate both to his Jamaican estate and business, and to his Scottish estate, from which he received added income from rents. The accounts for this estate continue for several decades after Tailyour’s death in 1815. A number of disparate and miscellaneous letters, war records, photographs, and realia that belonged to various members of the extended Tailyour family date mainly from the late-nineteenth and early-twentieth centuries.

The collection has three substantial parts. The most comprehensive and cohesive section is the one concerning John Tailyour, until his death in 1815. The second part contains business papers and accounts related to the Tailyour estate. The third part is the least integrated, and consists of a variety of family papers, photographs, military memorabilia, and other miscellanea.

The Tailyour papers date from 1743 to 2003, with the majority of the collection concentrating in the period from 1780 to 1840. Within these bulk dates, are the two largest portions of the collection: the correspondence and accounts of John Tailyour until his death in 1815, and the account records of the Tailyour estate after 1815.

Seven boxes contain John Tailyour's personal and business correspondence of 3757 letters. The letters focus on Tailyour's mercantile activities in the Atlantic market, especially on the slave trade, its profitability, and the threat posed by abolitionists. Tailyour's correspondence also chronicles personal and family matters, including the education and provision for his mixed-race children from Jamaica. In addition, the collection contains four of Tailyour's letter books of 1116 copies of retained letters that cover the period from 1780 to 1810, with the exception of the years 1786-7 and 1793-1803. In these letters, Tailyour's focus is business, particularly as it relates to the slave trade, but he also includes personal messages to his friends and family.

Tailyour's business papers contain 32 loose account records, as well as five account books documenting the years between 1789-90 and 1798-1816. These primarily concern his Kingston and Scottish estates, including the expense accounts and balance sheets for each, as well as the finances of his merchant activities during the period. Finally, 38 documents of probate records for John Tailyour mainly relate to his landed estate.

The latter portion of collection within these bulk years (1815-1840) also contains correspondence and accounts, although the 228 letters are almost entirely concerned with business accounts. These focus on Tailyour's estate after his death, with John's brother Robert as the main correspondent. Additional materials include 1761 business papers that chronicle the finances of the estate, 11 account books, and 6 hunting books. The business letters and account books detail the estate's expense accounts and receipts, as well as the balances for their annual crops, salmon fishing business, and profits derived from the rents collected on their land. The hunting books contain descriptive accounts of the family's hunts and inventories of their hunting dogs.

The third, and final, part of the collection consists of Tailyour family records (bulk post-1815), including 49 letters from various family members in the late-nineteenth and early-twentieth centuries and five letterbooks, kept by Alexander Renny Tailyour and Thomas Renny Tailyour. 4 account books are also present kept by Alexander Renny Tailyour and others. Some of the records concern the First World War, including a group of prisoner-of-war records sent from Germany, and journals kept at home that detail news of the war, and daily domestic activities.

The family history documents include 64 genealogical records and 58 probate records. Many of the genealogical items are brief notes on family history, and sketches of the family tree, including a large family tree that spans several hundred years to the present day. The probate records contain one will from the late-nineteenth century, but are otherwise entirely concerned with John Tailyour's estate in the years immediately after his death.

Of the printed records, Memoirs of my Ancestors (1884), by Hardy McCall is a genealogy of the McCall family, and Tailyour's Marykirk and Kirktonhill's estates are described in two printed booklets, one of which is an advertisement for Kirktonhill's sale in the early-twentieth century. Other printed material includes 14 various newspaper clippings concerning the family over the years, and 12 miscellaneous items.

The illustrations, artwork, and poetry comprise 14 fashion engravings, 12 sailing illustrations, a picture of a hunting cabin, two silhouettes, and a royal sketch, all of which date from the early- to mid-nineteenth century. Kenneth R. H. Tailyour's sketches are represented in two sketch books created in his younger years (1917 and 1920). Loose records of poetry, as well as a book of poems from George Taylor, are in this section.

The 221 photographs are of the Tailyour family from the late-nineteenth to the twentieth century, with the majority falling in the early decades of the twentieth century. Most are portraits of the Tailyour family from the early twentieth century, particularly Kenneth R. H. Tailyour.

The 138 pieces of ephemera are, for the most part, postcards of foxhunts during the nineteenth century. These announce the almost-weekly family foxhunts during the middle years of the nineteenth century. The 19 items of realia, include Robert Taylor's quill pen from 1826.

The audio-visual portion of the collection contains three items: a compact disc with an audio interview of John Dann, Director of the Clements Library, on National Public Radio's "The Todd Mundt Show;" a compact disc with photos of the West Indies; and a collection of photographs of the Tailyour papers in their uncatalogued state, and of the festivities surrounding the acquisition of the collection.

Finally, miscellaneous material of 18 pieces includes Robert Taylor's commonplace book of short stories, letters, and poems; the catalogue of Robert Taylor's books; James Tailyour's 1771 style and form book; and a communion book.

The Hinkley collection is comprised of an account book and exercise book owned by members of the Hinkley family of Georgetown, Maine, in the mid-18th and early 19th centuries. The materials pertain to John Hinkley's finances, Samuel P. Hinkley's finances and education, and religious poetry.

The Hinkley collection is comprised of an account book and exercise book owned by members of the Hinkley family of Georgetown, Maine, in the mid-18th and early 19th centuries. John Hinkley kept 125 pages of accounts from 1755-1779, Samuel P. Hinkley kept 3 pages of accounts from 1789-1805, and Samuel P. Hinkley recorded 56 pages of information about mathematics and navigational principles. The account book also has 8 pages of religious poetry.

The first 125 pages of John Hinkley's Account Book concern the period between June 1755 and May 1779, though most accounts are dated between 1755 and 1765. His double-entry records pertain to his purchases of chocolate, sugar, corn, meal, rum, molasses, and other foodstuffs, and some reflect his interest in a sawmill. Several aspects of the mill's business are covered, such as providing boards and hauling timber. John Hinkley frequently traded with other members of the Hinkley family, including Josiah Hinkley and Samuel Hinkley. The accounts are followed by 8 pages of religious poetry, with one poem attributed to Betsey Hinkley, and 3 pages of financial accounts that Samuel P. Hinkley sporadically recorded between December 1789 and June 1805.

Samuel P. Hinkley's Exercise Book, dated December 18, 1837, contains 56 pages of nautical navigational problems and exercises. Topics include plane sailing, traverse sailing, parallel sailing, middle latitude sailing, and Mercator sailing, as well as the method of ascertaining latitude by making observations. Hinkley recorded several case studies and accompanying exercises for each sailing method, and the book contains the mathematical calculations used to solve each problem. Some problems, particularly those in the traverse sailing section, are accompanied by tables. The last several pages are copied entries from an unnamed ship's log, originally recorded during a journey between Boston and Madeira in March and April 1824 and during an unspecified voyage in January 1824.

This volume was owned by successive generations of the Hoyt family in Stamford, Connecticut, and Hudson, Michigan, in the 18th and 19th centuries. Its contents include military accounts from St. Johns, Newfoundland; arithmetic problems and solutions; and drawings of animals and natural scenes, including two hunters' encounter with a bear.

This book was owned by successive generations of the Hoyt family in Stamford, Connecticut, and Hudson, Michigan, in the 18th and 19th centuries. The front cover of the hide-bound volume bears the faint remnants of the English royal arms. Writing on the inside of the front cover indicates that the volume was owned by Jonah Hoyt (or Hait) before being presented to his grandson, Fred L. Hoyt, on his 21st birthday. The early pages include 7 pages of accounts for the receipt of military stores and provisions at St. Johns, Newfoundland, between September 1762 and August 1764. The section also contains a birth register regarding the children of Jonah and Anna Polmateer Hoyt.

The bulk of the volume is mathematical problems and solutions, including exercises related to multiplication, division, fractions and decimals, currency reduction, and the rule of three (cross-multiplication). Several measurement conversion tables, brief poems, penmanship exercises, and geometric line drawings are interspersed throughout this portion of the book, which also includes signatures by Jonah Hoyt and his son Lewis. Most of the poems are brief and humorous, with longer poems concerning a visit to London and the virtue of patience. Newspaper clippings regarding the death and funeral of George Washington, the wealth of Cornelius Vanderbilt, presidential election results from 1789 to 1872, and Ralph Waldo Emerson's poem "Boston" are laid and pasted into the volume. A few plants are also laid in, as well as a letter from T. Andrews to Mary Andrews about life in Ypsilanti, Michigan, in February 1837. Decorated cutouts made from colored paper are pasted into the volume.

Emery Hoyt and other family members created many drawings, which appear after the arithmetic problems. Two are colored: a partially colored view of a church resembling a castle and a reproduction of an engraving showing a waterfront scene (the original engraving is laid into the volume). Most of the remaining pictures are pencil drawings and sketches of wild animals, including woodland creatures such as squirrels and deer; farm animals such as horses, cattle, and pigs; and African animals such as elephants, an oryx, and rhinoceroses. Other scenes of note show two hunters during an encounter with a bear, with one of the hunters preparing to hit the bear with the butt of his rifle; a safari hunter beside an elephant; and cavalry officers stabbing and shooting Native Americans. Also included are an outline of the state of Maine and a sketch of a sailing ship.

The Peter Aplin logbooks document Aplin's voyages on the British Navy ships Savage, Niger, Prudent, Strombolo, and Roebuck. The books detail travel between England, the Mediterranean, Africa, and India, and describe participation in naval battles and blockades in Revolutionary-era North America.

The five Peter Aplin logbooks (276 pages total) document his voyages on the British navy's ships Savage, Niger, Prudent, Strombolo, and Roebuck, from 1769 to 1777. The books detail travel to England, the Mediterranean, Africa, and India, and describe his participation in naval battles and blockades in Revolutionary-era North America. Entries typically note the ships’ daily location, the weather conditions, and other ship-related matters such as repairs, discipline, rations, and interactions with other ships. The bulk of the information about the crews on these voyages concerns discipline or death on board the ships. The Aplin logs do not, however, contain personal details. The first two volumes are in Peter Aplin's hand, while volumes 3, 4, and 5, are written by various anonymous crew members.

Volume 1 (91 pages) covers two voyages, the first being from Ireland to Northern Canada on board His Majesty's Sloop Savage, commanded by Andrew Snape Hammond, from March 6 to November 23, 1769. Entries are typically 2-5 sentences long and are full of technical details on how the crew maneuvered the ship and kept it afloat during a rough voyage, as well as disciplinary actions such as lashing and confinement. Starting off from Ireland's Blasket Islands, the Savage encountered many days of "hard gale," which forced the crew to throw the guns overboard to stop the ship from foundering (v.1, p.5). During this crisis, half the crew were needed at the pumps and even with that effort the "Main Deck was Constanly full of Water" (v.1, p.7). Finally, by April 15, after a turbulent trip along the south coast of England, the Savage moored at Portsmouth Harbor, where it was repaired and provisioned until May 28 (p.13-17). The Savage then set off across the northern Atlantic and arrived at St. John's Harbor in Newfoundland on July 29. The log offers few clues on the purpose for the voyage but notes that, once anchored, the ship bottom was scrubbed, the rigging set up fore and aft, and James Cunningham was confined "for Leaving [the] boat & getting Drunk" (p.26). On August 11, the Savage headed southward and moored at Bull Bay two days later. It made stops at Cape Broyle (August 24), and Capeling Bay, Newfoundland, (August 25), before returning to St. John's Harbor (September 12-18). It arrived back at Portsmouth Harbor in late September, where it stayed till the end of the Journal on November 23, 1769.

The second voyage in volume 1 is on board the HMS Niger, commanded by Francis Bankes, from April 1, 1770 to January 18, 1771. It left from Portsmouth, England, and traveled through the Mediterranean Sea with stops at Gibraltar, Cadiz, Genoa, and Smyrna. The entries are similar to the previous voyage’s log, noting interactions with foreign ships; on board activities while sailing and mooring; and disciplinary actions for negligence of duties, selling their clothes, and gambling. A few days after unmooring from Spithead, England (May 9, 1770), the Niger had a brief encounter with an unfriendly crew on another vessel. They "fired a Shot at a French Sloop for not paying proper respect to his Maj[esty's] Ship." (p.53) The Niger headed south past France and as they approached the waters of Portugal they fired three more shots at a Dutch ship, again, for not paying respect to the English Flag (May 20th). They reached Gibraltar on May 28th and moored at Cádiz Bay, Spain, from June 11-26. From July 20 to August 6, they moored at River Tagus near Lisbon, and continued further east, stopping at Greek and Turkish Islands, such as Smyrna Castle (in November) and Milo Harbor (in early December). The ship sailed west for the next month and on January 11, 1771, had arrived back at Gibraltar to restock food and supplies. The log ends on January 18th.

Volume 2 (85 pages) is a log for the ship Prudent, commanded by Sir Jonathan Clerke, for its journey from Spithead, England, to India by way of Madeira, Madagascar, Bombay, Trincomalee (Sri Lanka), and Madras (now Chennai), from April 9, 1772 to October 27, 1774. The ship left England on April 13, and arrived at Madeira, their first stop, on April 27 (p.5). The next leg took them to St. Augustine's Bay, Madagascar, where they stayed from August 15 to September 5, 1772 (p.15-17). They reached Bombay Harbor on October 29th, where they moored. During their long stay in Bombay, Aplin continued to take notes on weather, daily activities, and crew discipline, and also described their contact with other British naval officers and crews stationed there. Also during this period, the ship made several short trips to Trincomalee Harbor, Sri Lanka, and Madras, often accompanied by a larger fleet of British ships, including the Sloop Dolphin. The last dated entry of the journal was October 28, 1774, when the Prudent was on its way southeast from India. Notable events during the ship’s voyage include the death of a crew member on May 5th, "Departed this life of accident Robt. Libson" (p.7), and a court marital for Thomas Fennel and Pat Mahon for attempted mutiny, attended by all captains stationed at Madras; the penalty was 400 lashes (p.43).

Volume 3 (47 pages plus 14 blank pages) is the logbook of the Roebuck, commanded by Andrew Hammond during the British blockade of the American Atlantic coast, October 5, 1776 to July 14, 1777. Several entries mention “the Enemy” and describe various cannon discharges and chases of foreign ships trying to get past the British blockade. Other notable events include a "Divine service" given on board the Roebuck on Sunday, October 6, 1776 (p.5); accidents at sea, such as a man falling overboard on April 27, 1777 (p.33); and a crew member dying at the mast on May 18, 1777 (p.37). The journal begins with the Roebuck stationed near the mouth of the Hudson River near Manhattan in the days leading up to the British capture of Fort Washington. On October 9, the logbook notes that guns at Fort Lee and Fort Washington fired upon their fleet but they ceased firing when the ships got past the battery. The ships then anchored at Merlin's Landing, but one of the cutters was badly damaged in the encounter and was cut adrift. The Roebuck sustained damages and fatalities, and for days after the battle, between the 10th and the 16th, many men were "Committed…to the Deep" (p.5-7). On October 21, the ship was anchored at Haverstraw, New York, on the Hudson (South of Fort Montgomery) and over the next weeks, the log’s writer made note of when shots were fired, what ships they encountered, and where the ships were stationed, though they do not record any further battles. In December 1776 and January 1777 the Roebuck was part of the British blockade on the lookout for foreign ships. Many entries describe "giving chase," with some pursuits lasting two days. They let most of the ships go, though on some occasions Aplin mentions taking prisoners (p.17). Most of the vessels were headed to Boston, Virginia, and Philadelphia, with some coming from Cape Nichola Mola, such as a schooner captured on January 2, 1777, carrying sugar and molasses (p.17). At the end of January, the Roebuck headed north and on March 12, 1777, they arrived at St. John's Harbor, Newfoundland, where they worked on the ship, "Scrubbing Hammocks and wash'd between Decks" (p.29). The entries between pages 27-45 are in a different hand. The remainder of the journal records the ship patrolling off the coast of Delaware. On April 9th it was anchored at Fenwick Island (p.31) and over the next weeks, the ship visited Cape May and Bombay Hooks, where the crew occasionally carried out small arms exercises and observed fellow British ships returning with captured vessels.

Volume 4 (35 pages and 49 blank pages) contains logs for two ships: the Roebuck, commanded by Andrew Hammond, at ports along the southern and western coasts of England, July 14-September 30, 1775, and the Strombolo, commanded by Peter Aplin, anchored off Sandy Hook, July 14-September 21, 1778. For the first 9 pages of the log, the Roebuck was docked at Chatham, England (July 14-August 3, 1775). The ship was next moored near the North Shore of Sheerness, England, from August 4-22 where two men were received from the hospital (p. 9) and another was punished for thieving (p.11). The Roebuck cruised the south coast of England for the next 10 days, anchoring off the North Foreland (August 23), near Downs (August 24); at Spithead (August 27), near Yarmouth (September 5); at the Isle of Portland (September 10); and at Guernsey (September 14-30). The logbook for the Strombolo begins on page 20 with the ship anchored off Sandy Hook from July 14-September 21, 1778 (p. 20-25). At this time, the Strombolo was stationed with the British fleet and they received daily signals from Admiral Howe. The superior French fleet had gathered near Rhode Island and occasionally approached the British to try to engage them in a large-scale conflict. On July 17th, Aplin described a skirmish between the HMS Vigilant and some French vessels. After a few days of hard gales, the British fleet sailed north on August 8th (p.25) from Sandy Hook to the vicinity of Block Island. For the next six weeks, they sailed to Block Island, Cape Cod, Sandy Hook, and Montauk, along with British ships including the HMS St. Albans, Renoun, Ardent, Experiment, Emerald, Ariel, Delaware, Vigilant, Raisonnable, Phoenix and the Apollo (August 15-18). Aplin's ship and the HMS Richmond left the fleet on September 3, 1778.

Volume 5 (18 pages) contains hand-written copies of entries from the Roebuck voyages of Volume 3, covering the log entries of October 5 to December 18, 1776, and from May 17 to July 14, 1777.
