Lord Chesterfield, Letters to His Son (December 15, 1747):
I knew a gentleman, who was so good a manager of his time, that he would not even lose that small portion of it, which the calls of nature obliged him to pass in the necessary-house; but gradually went through all the Latin poets, in those moments. He bought, for example, a common edition of Horace, of which he tore off gradually a couple of pages, carried them with him to that necessary place, read them first, and then sent them down as a sacrifice to Cloacina: this was so much time fairly gained; and I recommend you to follow his example. It is better than only doing what you cannot help doing at those moments; and it will made any book, which you shall read in that manner, very present in your mind. Books of science, and of a grave sort, must be read with continuity; but there are very many, and even very useful ones, which may be read with advantage by snatches, and unconnectedly; such are all the good Latin poets, except Virgil in his “Aeneid”: and such are most of the modern poets, in which you will find many pieces worth reading, that will not take up above seven or eight minutes. Bayle’s, Moreri’s, and other dictionaries, are proper books to take and shut up for the little intervals of (otherwise) idle time, that everybody has in the course of the day, between either their studies or their pleasures. Good night.
