! 66 Gen. Roy’s Account of 
a good deal of trouble, by cutting off the tops of certain trees, 
lopping the branches of others, and railing a flag-flaff on the 
center of the fcaffold, thefe two Rations were rendered reci- 
procally vifible. By thefe means we not only avoided making 
ufe of Kew Pagoda, which, from the nature of the building, 
would have been a very incommodious Ration ; but we thereby 
o-ot rid of Clermont Tower altogether ; and thus, inRead of 
O 
two fmall triangles, one was conflituted, larger and better, 
being nearly equilateral. 
In the introduction there has been occafiou to take notice of 
the advantage that was gained by being able to fee Frant and 
Fairlight Down reciprocally. From this circumRance the feries 
from Frant eaRward to the bafe of verification becomes in 
reality a double one, and confequently affords better means of 
afcertaining the corrednefs of the work. 
The Angularity of the fituation of Dover Caflle has like- 
wife been mentioned. Inflead of two Rations near Tatterlees 
Barn and Barefriflan, whereby it was hoped, that Dover Caflle 
might have been conne&ed with the feries to the weffward, 
it was found neceflary to make ufe of three Rations ; one at 
Padlefworth, one at Folkffone Turnpike, and a third at 
Swingfield. Thus the fide which connects that ancient fort 
with the other triangles is fliorter than was intended. But 
with fuch an inffrument as ours, and where all the angles of 
the triangles were obferved, no uncertainty arifes on that 
account.
