"It is that," said the captain. "It has cleared away a cloud that might have hung over this ship till the mystery was dispelled, which probably would have been never."
Mr. Rosenstein, who had taken the diamonds from Jack, stood apparently stupefied, holding them on his palm. Suddenly, however, to Jack's great embarrassment, he threw both arms round the boy's neck and saluted him on both cheeks. Then he rushed at Billy and finally the two firemen, who dodged out of the way. Then he drew out a check book and began writing rapidly. He handed a pink slip of paper to Jack. It was a check for $5,000.
"A souvenir," he said.
"But—but——" began Jack, "we didn't do it for money. It was our duty to the company and——"
"It's your duty to the company to take that check, then," laughed Captain Turner, and in the end Jack did. The two firemen, who had helped the boys, received a good share of it and later were promoted by the company for their good work. As for Prof. Dusenberry and his companions, they vanish from our story when, in custody of the detectives, they went over the side a few minutes later. But Jack and Billy to-day have two very handsome diamond and emerald scarf-pins, the gifts of the grateful Mr. Rosenstein.
"Looks as if we are always having adventures of some kind or another," said Billy to Jack that evening as they strolled about the town, for the ship would not sail for Cherbourg, her last port before the homeward voyage, till the next day.
"It certainly does look that way," agreed Jack and then, with a laugh, he added:
"But they don't all turn out so profitably as this one."
With which Billy agreed.
