of that water must
pass by her sides, and with a swifter motion, which would retard her,
as moving the contrary way; or that the water becoming lower behind
the boat than before, she was pressed back by the weight of its
difference in height, and her motion retarded by having that weight
constantly to overcome. But as it is often lost time to attempt
accounting for uncertain facts, I determined to make an experiment of
this when I should have convenient time and opportunity.

After our return to England, as often as I happened to be on the
Thames, I enquired of our watermen whether they were sensible of any
difference in rowing over shallow or deep water. I found them all
agreeing in the fact, that there was a very great difference, but
they differed widely in expressing the quantity of the difference;
some supposing it was equal to a mile in six, others to a mile in
three, &c. As I did not recollect to have met with any mention of
this matter in our philosophical books, and conceiving that if
the difference should really be great, it might be an object of
consideration in the many projects now on foot for digging new
navigable canals in this island, I lately put my design of making
the experiment in execution, in the following manner.

I provided a trough of plained boards fourteen feet long, six inches
wide and six inches deep, in the clear, filled with water within half
an inch of the edge, to represent a canal. I had a loose board of
nearly the same length and breadth, that, being put into the water,
might be sunk to any depth, and fixed by little wedges where I would
chuse to have it stay, in order to make different depths of water,
leaving the surface at the same height with regard to the sides of
the trough. I had a little boat in form of a lighter or boat of
burthen, six inches long, two inches and a quarter wide, and one inch
and a quarter deep. When swimming, it drew one inch water. To give
motion to the boat, I fixed one end of a long silk thread to its
bow, just even with the water's edge, the other end passed over a
well-made brass pully, of about an inch diameter, turning freely on a
small axis; and a shilling was the weight. Then placing the boat at
one end of the trough, the weight would draw it through the water to
the other.

Not having a watch that shows seconds,

My scheme of Order gave me the most trouble;[70] and I found that, tho' it might be practicable where a man's business was such as to leave him the disposition of his time, that of a journeyman printer, for instance, it was not possible to be exactly observed by a master, who must mix with the world, and often receive people of business at their own hours.

Possibly, as they dislik'd my late intimacy with the members of council, who had join'd the governors in all the disputes about military preparations, with which the House had long been harass'd, they might have been pleas'd if I would voluntarily have left them; but they did not care to displace me on account merely of my zeal for the association, and they could not well give another reason.
