It was therefore natural that there should be some hesitation about keeping down the ball merely for the purpose of getting a boat off to send Ruby ashore.

“You see,” said Forsyth, “the day after to-morrow the ‘relief boat’ is due, and it may be as well just to wait for that, Ruby, and then you can go ashore with your friend Jamie Dove, for it’s his turn this time.”

“Ay, lad, just make up your mind to stay another day,” said the smith; “as they don’t know you’re here they can’t be wearyin’ for you, and I’ll take ye an’ introduce you to my little wife, that I fell in with on the cliffs of Arbroath not long after ye was kidnapped.  Besides, Ruby, it’ll do ye good to feed like a fighting cock out here another day.  Have another cup o’ tea?”

“An’ a junk o’ beef?” said Forsyth.

“An’ a slice o’ toast?” said Dumsby.

Ruby accepted all these offers, and soon afterwards the four friends descended to the rock, to take as much exercise as they could on its limited surface, during the brief period of low water that still remained to them.

It may easily be imagined that this ramble was an interesting one, and was prolonged until the tide drove them into their tower of refuge.  Every rock, every hollow, called up endless reminiscences of the busy building seasons.  Ruby went over it all step by step with somewhat of the feelings that influence a man when he revisits the scene of his childhood.  There was the spot where the forge had stood.

“D’ye mind it, lad?” said Dove.  “There are the holes where the hearth was fixed, and there’s the rock where you vaulted over the bellows when ye took that splendid dive after the fair-haired lassie into the pool yonder.”

“Mind it?  Ay, I should think so!”

Then there were the holes where the great beams of the beacon had been fixed, and the iron bats, most of which latter were still left in the rock, and some of which may be seen there at the present day.  There was also the pool into which poor Selkirk had tumbled with the vegetables on the day of the first dinner on the rock, and that other pool into which Forsyth had plunged after the mermaids; and, not least interesting among the spots of note, there was the ledge, now named the “Last Hope”, on which Mr. Stevenson and his men had stood on the day when the boat had been carried away, and they had expected, but were mercifully preserved from, a terrible tragedy.

After they had talked much on all these things, and long before they were tired of it, the sea drove them to the rails; gradually, as it rose higher, it drove them into the lighthouse, and then each man went to his work—­Jamie Dove to his kitchen, in order to clean up and prepare dinner, and the other two to the lantern, to scour and polish the reflectors, refill and trim the lamps, and, generally, to put everything in order for the coming night.

Ruby divided his time between the kitchen and lantern, lending a hand in each, but, we fear, interrupting the work more than he advanced it.
