here 
we left a mark.

This finiftied the line A B. fThe breadth of the rivers was found by 
Hence AB=r 2 1 696.47 levels + 892,34 in- J meafuring a bafe, and taking angles with 
ches +94,51 inches = 43401 1,64 feet. I a Hadley’s quadrant. 
Note. The reckoning was kept by ftretching a rope in the line to be meafured (in 
general) = 12 levels, which was often proved .; and it was almoft impoflible that an 
error could arife ; as we always began the rope with the fame level, and ended it with 
the other; the rope not being removed till the laft level was fet. 
The perfon that ftretched the rope, fometimes Mr. Dixon, and fometimes myfelf, 
kept the account of the number of ropes meafured : though the mile ports in the lines 
AB and DC were fufficient for that purpofe, as the lines had been fo often meafured 
before. 
In the line NP there were no mile ports, but two or three intermediate marks, which 
we found to agree in a general law with the levels. 
Supporting the levels exadtly =20 feet each ; then in the line NP a mile per chain 
meafure = a mile and 9,44 feet by the levels ; and in the line CD a mile per chain 
meafure = a mile and 9,86 feet by the levels.
