"You've got it all off by heart, I see," said Ruby.

"True, boy, but it's not so easy to get it all off yer stomach sometimes. What with confinement and want of exercise we was troubled with indigestion at first, but we're used to it now, and I have acquired quite a fancy for cooking. No doubt you'll hear Forsyth and Joe say that I've half-pisoned them four or five times, but that's all envy; besides, a feller can't learn a trade without doin' a little damage to somebody or something at first. Did you ever taste blackbird pie?"

"No," replied Ruby, "never."

"Then you shall taste one to-day, for we caught fifty birds last week."

"Caught fifty birds?"

"Ay, but I'll tell ye about it some other time. Be off just now, and get as much exercise out o' the rock as ye can before breakfast."

The smith resumed his work as he said this, and Ruby descended.

He found the sea still roaring over the rock, but the rails were so far uncovered that he could venture on them, yet he had to keep a sharp lookout, for, whenever a larger breaker than usual struck the rock, the gush of foaming water that flew over it was so great that a spurt or two would sometimes break up between the iron bars, and any one of these spurts would have sufficed to give him a thorough wetting.

In a short time, however, the sea went back and left the rails free. Soon after that Ruby was joined by Forsyth and Dumsby, who had come down for their morning promenade.

They had to walk in single file while taking exercise, as the tramway was not wide enough for two, and the rock, even when fully uncovered, did not afford sufficient level space for comfortable walking, although at low water (as the reader already knows) it afforded fully a hundred yards of scrambling ground, if not more.
