This diary records the individuals and sights that he saw while in England. There are many observations of life in London, e.g. parks, buildings, paintings, food. Outside of London he visited many towns, including Manchester and its cotton mills as well as the steel mills of Birmingham. He relates his visit to Drury Lane and the dramatic performance of Sarah Siddons. Some of the people he met included Sir Joseph Banks, Sir Charles Blagden, Matthew Boulton, Joseph Priestley, William Pitt the Younger, and Benjamin Vaughan. He also visited and described the gardens at Kew. The diary includes several sketches, including the plan of Blenheim Palace, and also a table of distances traveled. This item is written in the hand of Jean-Francois Wiart.
 

Researchers will likely gravitate to Strahan's first volume, a detailed, six-week account of European travels taken in 1751 (7/6-8/28). Alongside accounts of weather, road and travel conditions, and various social gatherings (e.g. breakfasts, dinners, teas), Strahan's entries offer glimpses into eighteenth-century English conduct, church services, universities, courts, libraries, as well as villages, towns, and cities and their inhabitants. For example, Straham describes Newcastle as a "a place of Business and Industry equal to London" (7/15) and Paisley as a "perfect hive of industrious people" (8/6). Attending a trial, he remarks upon the conduct of the participants, writing, "The court was very solemn and the lawyers were both elegant and behaved with remarkable decency" (7/22). Strahan even visits a poorhouse in Edinburgh, by which, he remarks, "the City is not only freed of all beggars, but the offspring of such are [tirelessly] snatched from Destruction, so that the Race of disorderly people are hereby extinguished" (7/30).
 
The second (1759, 1760, 1766), third (1768, 1773, 1777), and fourth volumes (1755-1761) are much less detailed but sketch his travel (and distances covered). The fourth volume, in particular, more closely resembles an account book than a journal. As he takes stock of his properties, assets, and debts, Straham records his increasingly wealth—from £ 5,000 in total assets in 1755 to £ 12,000 in 1761.

The William Strahan diary encompasses four volumes spanning 1751-1777. The first volume features the most detailed entries, whereas the second and third volumes include shorter accounts of multiple excursions and the fourth volume serves less as a journal than a summation of accounts, debts, and holdings. The first volume's accounts of mid-eighteenth-century England ought to interest researchers interested in English urban space, governance, and social conduct.
