“I imagine the worst is over,” said Professor Strong, after a painful silence. “Unless I am mistaken that accident was nothing worse than the ripping open of some steam pipes. But it may have cost the life of a fireman, coal heaver, or engineer. If you will all remain here I will investigate.”

They promised to stay where they were and he left them, to be gone the best part of quarter of an hour. In the meantime quietness was restored on board, and some of the passengers went back to the cabin, which was now free of steam.

“It was as I surmised,” said the professor. “Two pipes burst and let out an immense amount of steam. One of the firemen had his leg scalded and an engineer had his left hand badly lacerated. They are now repairing the damage done, and they say that by morning we will be able to steam along the same as usual.”

“I’m glad to know it’s no worse,” observed Frank, while Hockley wiped the cold perspiration from his forehead. “But it’s queer the pipes should burst. They must be old.”

“The engineer says he told Captain Sudlip about the pipes needing repairs before we left La Guayra. But the captain put him off and told him that he would have the repairs made at Havana.”

“If that’s the case then that fireman and that engineer will have it in for him,” was Mark’s comment.

“And they ought to have it in for him,” came from Frank. “Those men might have been steamed to death, and we might have been blown up in the bargain.”

“Just what I say,” added Sam.

The rain soon cleared off and that evening the countless stars came out to brighten up the view of the sea. The boys made themselves easy on the deck, taking in the scene, the single exception being Hockley, who sat close to a cabin light, reading a novel he had picked up at a bookstall in La Guayra.

“Did you see that novel Glummy is reading?” said Sam to Frank, as he drew up his chair.
