along channels made in the floor to form flat, squarish ingots of
tin, and display the colours of the rainbow, intensified to a brilliancy
that was almost more than the eye could bear.

"Please father when he hears of the casting," said Joe. "So much money
has been laid out that he likes to hear of anything that will bring a
return."

"Well, there's plenty of return coming in now," said Gwyn. "We've got
one of the richest mines in Cornwall. Here, Tom Dinass! What's he mean
by sneaking away? Here, Tom Dinass!"

"Want me, sir?" said the man, looking from one to the other suspiciously
as he came up, his face shining in the wonderful glow shed by the molten
tin.

"Yes, of course. Didn't you see us coming to you before?"

"Me, sir? No, I didn't know as you wanted me," and he seemed to draw

"Well, we do," said Gwyn. "We want to have out the seine to-night; the
tide will fit, and there have been mullet about."

metal still glowing, "it would soon be roast dog if I had my chance."

Meanwhile the boys went on to continue their preparations, and then
hurried home for their meal; then for the first time Gwyn thought of
Grip, and whistled to him to come and be tied up, but the dog did not
come.

"Smelt a rabbit somewhere," said Gwyn, and thought no more about the
dog.

In due time Dinass appeared down by the sandy cove, and after the long
seine had been carefully laid in the stern of the boat, and the end
lines left in charge of a couple of miners on one of the points, the
boat was rowed straight out, with Gwyn paying out the net with its lead
line and cork line running over a roller in the stern. Then at a
certain distance the boat was steered so as to turn round to the righ
