Tom, however, was resourceful. With the electrical apparatus from the wrecked airship, he built a wireless plant, and sent messages for help, broadcast over the ocean.
They were finally heard, and answered, by an operator on board the steamer Camberanian, which came on under forced draught, and rescued Tom and his friends. It was only just in time, for, no sooner had they gotten aboard the steamer in lifeboats, than the whole island was destroyed by an earthquake shock.
But Tom, the parents of Mary Nestor, Mr. Damon, Mr. Fenwick, and all the others, got safely home. Among the survivors from the yacht Resolute was a Mr. Barcoe Jenks, who now, most unexpectedly, had confronted Tom through the glass window of the jewelry store. Mr. Jenks was a peculiar man. Tom discovered this on Earthquake Island. Mr. Jenks carried with him some stones which he said were diamonds. He asserted that he had made them, but Tom did not know whether or not to believe this.
When it seemed that the castaways would not be saved Mr. Jenks offered Tom a large sum in these same diamonds for some plan whereby he might escape the earthquakes. Mr. Jenks said there was a certain secret in connection with the manufactured diamonds that he had to solve--that he had been defrauded of his rights--and that a certain Phantom Mountain figured in it. But Tom, at that time, paid little attention to Mr. Jenks' talk. The time was to come, however, when he would attach much importance to it.
When this story opens, Tom was more interested in Mr. Barcoe Jenks than in any one else, and was wondering what he wanted to see him about. The young inventor could not quite understand how Mr. Track, the jeweler, could come back with a lad he suspected of being a thief, when the person who had acted so suspiciously, and who had knocked on the glass, was the queer man, Mr. Jenks.
“Yes, Tom I caught him,” the jeweler went on. “I chased after him, and nabbed him. It was hard work, too, for I'm not a good runner. Now, you little rascal, tell me why you tried to rob my store?” and the diamond merchant shook the lad roughly.
“I--I didn't try to rob your store,” was the timid answer.
“Well, perhaps you didn't, exactly, but your confederates did. Why did you rap on the glass, and why were you staring in so intently?”
