122 were probably smelting during the same period, indicating that a considerable quantity of tin was raised in their neighbourhood."

Anciently, before the introduction of the wheel, the smelting-place above all others was at King's Oven, or Furnum Regis, near the Warren Inn, between Post Bridge and Moreton. It is mentioned in the Perambulation of Dartmoor, made in 1240. It consists of a circular inclosure of about seventy-two yards in diameter, forming a pound, with the remains of a quadrangular building in it. The furnace itself was destroyed some years ago. When the inclosure was made it was carried to a cairn that was in part demolished, to serve to form the bank of the pound. This cairn was ringed about with upright stones, and contained a kistvaen. The latter was rifled, and most of the stones removed to form the walls; but a few of the inclosing uprights were not meddled with, and between two was found firmly wedged a beautiful flint scraper.

As the drift tin was exhausted, and the slag of the earlier miners was used up, it became necessary to run adits for tin, and work the veins. These adits remain in several places, and where they have been opened have yielded up iron bars and picks. But these are not more ancient than mediæval times, probably late in them. That gold was found in the granite rubble of the stream-beds is likely. A model of a gold-washing apparatus was found on the moor a few years ago. It was made of zinc.
