48 flint scrapers are found for cleaning the hides, plenty of rubber-stones for smoothing seams, plenty of small knives for cutting up meat, but hardly a spear-head, and arrow-heads are comparatively scarce. Their most formidable camp is at Whit Tor, the soil of which is littered with flint chips. It did not, on exploration, yield a single arrow-head. The pounds were inclosed to protect the sheep and young cattle against wolves, not to save the scalps of their owners from the tomahawks of their fellow-men. With regard to the numbers of people who lived on Dartmoor in prehistoric times, it is simply amazing to reflect upon. Tens of thousands of their habitations have been destroyed; their largest and most populous settlements, where are now the "ancient tenements," have been obliterated, yet tens of thousands remain. At Post Bridge, within a radius of half a mile, are fifteen pounds. If we give an average of twenty huts to a pound, and allow for habitations scattered about, not inclosed in a pound, and give six persons to a hut, we have at once a population, within a mile, of 2,000 persons.

Take Whit Tor Camp. To man the wall it would require 500 men. Allow to each man five noncombatants; that gives a population of 2,500. There are pounds and clusters of hut circles in and about Whit Tor that still exist, and would have contained that population. Take the Erme valley, high up where difficult of access; the number of huts there crowded on the hill slopes is incredible. On the height is a cairn, surrounded by a ring of stones, from which leads a line of upright blocks for a
