WATER IS FLAT: EARTH IS FLAT
the earth is a globe, the surface of the six miles length of water would have been six feet higher in the centre than at the two extremities, as shown in diagram (Fig. 1), but as the telescope was only eight inches above the water, the highest point of the surface would have been at one mile from the place of observation; and below this point the surface of the water at the end of the remaining five miles would have been sixteen feet."
Seat
Fio. 1.
Let A. B. represent the arc of water six miles long, and A.G. the line of sight. The point of contact with the arc would be a D, a distance of one mile from the observer at A. From D. to the bridge at B. would be five miles, ond the curvative from D. to B. would be sixteen feet eight inches. The top of the flag was five feet high and it would have been eleven feet eight inches below the horizon at D., and altogether out of sight. Such a condition was not observed; but the following diagram (Fig. 2) exhibits the true state of the case A.B. the line of sight, equi-distant from and parallel with surface of the water throughout the whole distance of six miles, "From which it is concluded that the surface of standing water is NOT CONVEX, but absolutely HORIZONTAL".

Experiment 2
"Along the edge of the water, in the same canal, six flags were placed, one statute mile from each other, and so arranged that the top of each flag was five feet above the surface of the water. Close to the last flag of the series a longer staff was fixed, bearing a flag three feet square, the top of which was eight feet above the surface of the water and the bottom in a line with the tops of the other intervening flags".
"On looking with a good telescops over and along the flags from A to B the line of sight fell on the lower part of the larger flag at B. The altitude of the bottom of B above the water at D, was five feet, and the altitude of the telescope at A above the water at C was five feet, and each intervening fiag had the same altitude. Hence the surface of the water C. D. was equi-distant from the line of sight A. B. and as A, B, was a right line, C, D being parallel, was also a right line, or, in other words, the surface of the water. C. D. for six miles was absolutely horizontal.
