Numerous cairns crown the heights. One immense tumulus, King's Barrow, has at some unknown time been excavated with great labour.
The great central trackway crosses Hamildon, and is very perfect where it does so. It had apparently no connection whatever with Grimspound.
From Grimspound may be seen, on the brow of the ridge connecting Birch Tor and Challacombe Down, a series of stone rows. They lead to a blocking-stone, or menhir, at the south extremity. The northern end has been destroyed by tin- streamers, whose works in Chaw Gully are interesting, for mining has been combined with streaming. The rock has been cut through, but no signs of the use of iron wedges for splitting the granite can here be discovered. It is traditionally told that what was done was to cut a groove in the granite, fill that with quicklime, and pour water on it. The lime in swelling split the rock. Ravens nest here; and I have seen rock doves and the pair of ravens nesting almost side by side.
Below is the Webburn, the stream turned up by tinners. There one mine continues in activity—the "Golden Dagger." Above is Vitifer, where fortunes have been made—and lost; mostly the latter by investors, mainly the former by the "captains" and promoters.
