"A water-wheel probably stood in the eastern recess of the house, for there is a covered drain leading from here right under the house and out at the western end, where the water was discharged into the river. Traces of the leat which supplied the motive power to this wheel may also be seen.
"What appear to be the remains of the furnace, consisting of massive stones placed vertically, and inclosing a small rectangular space, are plainly visible. In this place, lying askew, as if it had been thrown out of position, is a large stone containing a long, shallow cavity, which may have been the bottom of the furnace or 'float,' i.e. the cavity in which the molten tin collected before being ladled into the mould.
"This ruin lies at the nether end of deep, open cuttings, which start from near Rundlestone Corner, and are continued right down to the Walkham.
"About 1,000 yards up stream is the ruin of the other blowing-house, with remains of a wheel-pit and a leat. There is also a stone containing a mould 16 inches long at the top, 11 inches wide, and 6 inches deep. It is bevelled, so that the bottom length is 12½ inches, with a width of 8 inches. Like the mould-stone in the ruin below, it contains a sample ingot mould 3½ inches long, 3 inches wide, and 2 inches deep. The remains in these ruins are very similar to each other, and these blowing-houses were probably smelting during the same period, indicating that a considerable quantity of tin was raised in their neighbourhood."[13]
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.
According to an old Irish historical narrative, a bard was wont to carry a wand of "white bronze" or tin, and his shoes were also tin-plated.[14] One wonders whether at any time a bard thus shod and with his rod of office strode over Dartmoor and chanted historic ballads there!
For such as would care to see these dry bones of antiquarian research into the past of tin-streamers clothed with flesh, I must refer them to my novel of Guavas the Tinner, in which I have described the mode of life of the metal-seekers on the moor in the time of Elizabeth.
