"Whew! that alters the case," cried Forsyth, seizing his friend's hand, and wringing it heartily.

"Hallo! you two seem to be on good terms, anyhow," observed Jamie Dove, whose head appeared at that moment through the hole in the floor by which the lantern communicated with the room below. "I came to see if anything had gone wrong, for your time of watch is up."

"So it is," exclaimed Forsyth, rising and crossing to the other side of the apartment, where he applied his lips to a small tube in the wall.

"What are you doing?" enquired Ruby. "Whistling up Joe," said Forsyth. "This pipe runs down to the sleepin' berths, where there's a whistle close to Joe's ear. He must be asleep. I'll try again."

He blew down the tube a second time and listened for a reply, which came up a moment or two after in a sharp whistle through a similar tube reversed; that is, with the mouthpiece below and the whistle above.

Soon after, Joe Dumsby made his appearance at the trapdoor, looking very sleepy.

"I feels as 'eavy as a lump o' lead," said he. "Wot an 'orrible thing it is to be woke out o' a comf'r'able sleep."

Just as he spoke the lighthouse received a blow so tremendous that all the men started and looked at each other for a moment in surprise.

"I say, is it warranted to stand anything?" enquired Ruby seriously.

"I hope it is," replied the smith, "else it'll be a blue lookout for us. But we don't often get such a rap as that. D'ye mind the first we ever felt o' that sort, Forsyth? It happened last month. I was on watch at the time, Forsyth was smokin' his pipe in the kitchen, and Dumsby was in bed, when a sea struck us with such force that I thought we was done for. In a moment Forsyth and Joe came tumblin' up the ladder—Joe in his shirt. 'It must have been a ship sailed right against us,' says Forsyth, and with that we all jumped on the rail that runs round the lantern there and looked out, but no ship could be seen, though it was a moonlight night. You see there's plenty o' water at high tide to let a ship of two hundred tons, drawin' twelve feet, run slap into us, and we've sometimes feared this in foggy weather; but it was just a blow of the sea. We've had two or three like it since, and are gettin' used to it now."
