“At a short distance to the south-east and south-west there are cairns, which have been explored.” For this monument I have used the 6-inch map, as the circle lies nearly at the centre, and all the outstanding stones are within its limits. The heights of the sky-line were measured by Mr. H. Bolitho at a subsequent visit with a miner’s dial; the resulting declinations have been calculated by Mr. Rolston. A theodolite survey will doubtless revise some of them:-- Marks. Az. Hills. Dec. Star. Date. 1. F. Stone cross N. 43° 15′ E. 2° 7′ +29° 26′ Capella 2250 2. P.

Bolitho has been good enough to send me that modern hedges and farming operations have changed the conditions of the sight-lines, so that 1 and 3 are just invisible from the circle. This is by no means the only case in which the sighting stone has just been hidden over the brow of a hill and in which signals from an observer on the brow itself have been suggested, or a _via sacra_ to the brow from the circle; there are many monoliths in this direction which certainly never belonged to the circle. From the menhir P (No. 2) a fine view is obtained from N. to S. through E., so that the Blind Fiddler and the two large menhirs, and almost the circle, are visible. The curious shapes of 1 and 2 are noted, the east face vertical and the west boundary curved, like several sighting stones on Dartmoor.
