Up and to my office a little, and then to Brown’s for my measuring rule, which is made, and is certainly the best and the most commodious for carrying in one’s pocket, and most useful that ever was made, and myself have the honour of being as it were the inventor of this form of it. Here I staid discoursing an hour with him and then home, and thither came Sir Fairbrother to me, and we walked a while together in the garden and then abroad into the cittie, and then we parted for a while and I to my Viall, which I find done and once varnished, and it will please me very well when it is quite varnished. Thence home and to study my new rule till my head aked cruelly. So by and by to dinner and the Doctor and Mr. Creed came to me. The Doctor’s discourse, which (though he be a very good-natured man) is but simple, was some sport to me and Creed, though my head akeing I took no great pleasure in it. We parted after dinner, and I walked to Deptford and there found Sir W. Pen, and I fell to measuring of some planks that was serving into the yard, which the people took notice of, and the measurer himself was amused at, for I did it much more ready than he, and I believe Sir W. Pen would be glad I could have done less or he more. By and by he went away and I staid walking up and down, discoursing with the officers of the yard of several things, and so walked back again, and on my way young Bagwell and his wife waylayd me to desire my favour about getting him a better ship, which I shall pretend to be willing to do for them, but my mind is to know his wife a little better. They being parted I went with Cadbury the mast maker to view a parcel of good masts which I think it were good to buy, and resolve to speak to the board about it. So home, and my brother John and I up and I to my musique, and then to discourse with him, and I find him not so thorough a philosopher, at least in Aristotle, as I took him for, he not being able to tell me the definition of final nor which of the 4 Qualitys belonged to each of the 4 Elements. So to prayers, and to bed, among other things being much satisfied with my new rule.
