Up by four o’clock and to my office, and by and by Mr. Cooper comes and to our modell, which pleases me more and more. At this till 8 o’clock, and so we sat in the office and staid all the morning, my interest still growing, for which God be praised. This morning I got unexpectedly the Reserve for Mr. Cooper to be maister of, which was only by taking an opportune time to motion [it], which is one good effect of my being constant at the office, that nothing passes without me; and I have the choice of my own time to propose anything I would have. Dined at home, and to the office again at my business all the afternoon till night, and so to supper and to bed. It being become a pleasure to me now-a-days to follow my business, and the greatest part may be imputed to my drinking no wine, and going to no plays.
