A Book of Cornwall

by S. Baring-Gould

Now, when the granite came to the surface, it did not have everything its own way, and hold its nose on high, and lord it over every other rock as being the most ancient of all, though not the earliest to put in an appearance. There was a considerable amount of water about. There is plenty and to spare in the west of England now, but we may feel grateful that we do not exist in such detestable weather, nor exposed to such sousing rains, nor have to stand against such deluges, as those which granite had to encounter. Hot, over-hot, it may have been below, but it was cold and horribly wet above.

The rains descended; the floods came, and beat on the granite, which, being perhaps at the time warm and soft, and being always very absorbent, began to dissolve.

As it dissolved, the water swept away all its component parts, and deposited the heaviest near at hand, and took the lightest far away. Now the heaviest of all were the ore from the veins or lodes, and the water swept this down into the valleys and left it there, but it carried off the dissolved feldspar and deposited it where it conveniently could and when it was tired of carrying it. The former is stream-tin; the latter is china clay.

Now to get at stream-tin very little trouble is needed. The rubble brought down and lodged in the valleys has to be turned over; and the ore is distinguishable by its weight and by a pink tinge, like the rouge ladies were wont (a hundred years ago) to put on their cheeks and lips. There is no tunnelling, no nasty shafts and adits to be made; and shafts and adits were beyond the capacity of primitive man, furnished with bone and oak picks only. Besides, why take the trouble to mine when the tin lay ready to be picked up?

The story told in Cornwall of the discovery of tin is this:--

S. Piran came over from Ireland in a coracle, and, like a prudent man, brought with him a bottle of whisky. On landing on the north coast he found that there was a hermit there named Chigwidden. The latter was quite agreeable to be friends with the new-comer, who was full of Irish tales, Irish blarney, and had, to boot, a bottle of Irish whisky. Who would not love a stranger under the circumstances? Brothers Chigwidden and Piran drank up the bottle.

"By dad," said Piran, "bothered if there be another dhrop to be squeezed out! Never mind, my spiritual brother; I'll show you how to distil the crayture. Pile me up some stones, and we'll get up the divil of a fire, and we shall manage to make enough to expel the deuce out of ould Cornwall."

So Chigwidden collected a number of black stones, and the two saints made a fine fire--when, lo! out of the black stones thus exposed to the heat ran a stream like liquid silver. Thus was tin discovered.

The story won't wash.

Tin was invented a thousand years at least before either Piran or Chigwidden were thought of. But that was most certainly the way in which it was revealed.
