Up by five o’clock, and after my journall put in order, to my office about my business, which I am resolved to follow, for every day I see what ground I get by it. By and by comes Mr. Cooper, mate of the Royall Charles, of whom I intend to learn mathematiques, and do begin with him to-day, he being a very able man, and no great matter, I suppose, will content him. After an hour’s being with him at arithmetique (my first attempt being to learn the multiplication-table); then we parted till to-morrow. And so to my business at my office again till noon, about which time Sir W. Warren did come to me about business, and did begin to instruct me in the nature of fine timber and deals, telling me the nature of every sort; and from that we fell to discourse of Sir W. Batten’s corruption and the people that he employs, and from one discourse to another of the kind. I was much pleased with his company, and so staid talking with him all alone at my office till 4 in the afternoon, without eating or drinking all day, and then parted, and I home to eat a bit, and so back again to my office; and toward the evening came Mr. Sheply, who is to go out of town to-morrow, and so he and I with much ado settled his accounts with my Lord, which, though they be true and honest, yet so obscure, that it vexes me to see in what manner they are kept. He being gone, and leave taken of him as of a man likely not to come to London again a great while, I eat a bit of bread and butter, and so to bed. This day I sent my brother Tom, at his request, my father’s old Bass Viall which he and I have kept so long, but I fear Tom will do little good at it.
