THE TIN-MOULD STONES
7 inches at one end and 8 inches at the other. One end of the mould has a narrow gutter leading from the top to halfway down the mould. This was probably used for the insertion of a piece of iron prior to the metal being run in, thus permitting the easy withdrawal of the block of tin when cool from the mould. This stone also contains a small bevelled ingot or sample mould, 4 inches long, 2 inches wide, and 1¼ inches deep.
"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.

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.

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-
