Separated from association with their former illustrious owner, the bound volumes, which are mostly English books, present but few attractions. Among them are a few treatises on the art of war and military tactics, which evidently were never much read. These were imported after his unfortunate expedition with Braddock's army, and before the revolutionary war. There are books on horse and cattle diseases; on domestic medicine; on farming, and on religious topics--such works as we might expect to find on the shelves of a intelligent Virginia planter. It is evident that their owner was no student or specialist. Many of the books were sent to him as presents, with complimentary inscriptions by the donors. The bindings are all in their original condition, and generally of the most common description. The few exceptions were presentation copies. Col. David Humphreys, Washington's aid-de-camp during the revolutionary war, presents his "Miscellaneous Works," printed in 1790, bound, regardless of expense, by some Philadelphia binder, in full red morocco, gilt and goffered edges, and with covers and fly-leaves lined with figured satin. As the book was for a very distinguished man, the patriotic binder has stamped on the covers and back every device he had in his shop. Nearly all the volumes have the bold autograph of "Go. Washington," upon their title pages, and the well-known book-plate, with his name, armorial bearings, and motto, _Exitus acta probat_,[1] on the inside of the covers.
