And riddled it was, from top to bottom, with the back and one side wall completely demolished. In the street the wreckage lay five or six feet deep, and over all was the mud and lava dust, still hot. The boys’ feet were uncomfortably warm and looking at their shoes they found that the soles were seared as by a hot iron.

There was no sign of life about the hotel. In one of the windows hung the half doubled up body of a man, burnt beyond all possible recognition. As the lads gazed at it a shiver passed over them impossible to suppress. Could that be—but no, it was too horrible—they would not believe it.

“Let us go!” whispered Frank, hoarsely. “I—I can’t stand it!” And he swayed as if about to faint.

Mark caught his chum by the arm, and both picked their way to where they had left John Waterbury. Nothing could be accomplished while the ruins were so hot, and the American business men accompanied them back to the shore below St. Pierre. Here they learned that the warship had sailed to another quarter of the island, but a relief boat named the Ridalla was at hand, and they were taken on board this craft and made to feel at home.

From those on board of the Ridalla, Mark and Frank learned that the Vendee had been spoken several hours before, and that the steamer was now heading back to Martinique. She had suffered, as we already know, but nothing had been lost but a number of ropes and a corner of the cabin, which were burnt away.

“I’m glad they are safe,” said Mark. “The Vendee might have suffered like the Roraima and those other ships.”

An hour later a lookout announced the appearance of the Vendee, and not long after this the steamer came into the harbor and dropped anchor. At once Mark and Frank begged to be taken on board and their wish was speedily granted.

“Mark! Frank!” The cry came from Darry, who chanced to be on deck, and the next moment the lad was fairly hugging the pair. “Well of all that is wonderful! We had given you both up as lost!”

“We’ve had a hard time of it,” answered Mark. “How did you make out?”

“Oh, we caught our share too, I can tell you that. The fire rained all over the ship and we had to fight it like mad for over an hour. The professor was overcome and Sam and I were afraid he was dead. But he got over it after a while, and now he is as well as ever. I suppose St. Pierre is a sight. But tell me how you escaped being drowned. But no, come into the cabin first and see the others.”
