Diary of a Dean by Merewether. 23 Aug 1849. 21st, — Whilst the men were commencing their work at the large barrows on the preceding day, a shepherd stated that one of the boys had told him that he had "hooked" up out of a little barrow on Bye Down Hill a crock, but he knocked it to bits with the stick. On visiting the spot, about a mile north-east, it appeared to be a very small barrow, without any trench round it, and very little elevated; the turf on this part of the down is much broken. At the top of the barrow were evidently the remains of an urn, of a pottery apparently more compact than those recently discovered; and from the holes in the turf, in different directions, various fragments might be collected (H). Almost at the verge of the barrow was a trackway, having a trench on either side; but it was not easy to trace it for more than two miles, in consequence of the cultivation of the hills; it runs nearly east and west; traversing in the easterly direction from this spot the down called "Temple" Down, on which, near its course, is a hut designated by the grandiloquent title of "Glorian."1
Note 1. "Gloria Tanaris." as suggested by the site, as connected with the worship of Mr Bowes, from the possilble sanctity of that deity.
