Trigonometrical Survey. £53 



After the conclusion of this operation, we proceeded to select 

 such stations in the neighbourhood of the base, as might afford 

 means of connecting it with the triangles carried on in the prece- 

 ding year, The two chosen for this purpose, were Dundon Beacon, 

 and a spot near the village of Moor Lynch ; both nearer to their 

 respective ends of the base than we wished to have found them ; 

 yet, as small rods of only an inch in diameter were placed on 

 those stations, when they were observed from Dundon Beacon 

 and Moor Lynch, and the same erected at the ends of the base, 

 when they were observed from those stations, it becomes pro- 

 bable that very trifling errors resulted from this proceeding. 



The station at Ash Beacon was visited subsequent to these 

 just spoken of, and afterwards that on the Mendip Hills, for the 

 purpose of taking the angle between Moor Lynch and Dundon 

 Beacon. The operations of 1798 then terminated with a dili- 

 gent search after some spot in Cornwall, for a base of only two 

 or three miles in length : this search, however, was fruitless, as 

 in fact we had reason to imagine it would prove to be ; but we 

 were not willing to relinquish the hope, that a piece of ground 

 might be discovered proper for so confined a purpose. The 

 contrary, however, being the case, the party returned to London 

 in October.
