“Out searching for horned toads and web-footed lizards,” said Nellie. “He has enlisted the services of Ponto, and they are continually on the hunt. I hope he gets what he wants.”

“He generally does,” said Bob. “If he doesn’t he finds something else nearly as good.”

Some days later Mr. De Vere called at the bungalow. He had finished up his business affairs, and brought the boys the prize money, as their reward for the parts they had played in the finding of the derelict.

“But this is too much,” protested Jerry, when Mr. De Vere had given him and his comrades nearly half as much again as was originally promised.

“Not a bit of it,” was the reply. “I can well afford it. Those papers were more valuable than you supposed, and I find I will be able to collect insurance on the cargo of the abandoned brig. I have heard from the captain of it, and he tells me, just as I supposed, that he and the crew left her because of the peculiar fumes, so that my theory was right, after all. They tried to take the dogs, which belonged to the first mate, but could not.”

“Did you hear anything more of Blowitz?” asked Ned.

“Yes,” replied Mr. De Vere, rather solemnly. “Blowitz was killed shortly after the tug gave up the chase.”

“How?”

“The boiler blew up when the tug was trying to tow the derelict in, and he and several of the crew were burned to death. The survivors floated on the wreckage until they were picked up. So I have nothing more to fear from Blowitz. But I called to know if you boys, and the young ladies, Mr. Seabury and Professor Snodgrass, would not be my guests at a little dinner I am to give at the hotel. I want to show you that I appreciate what you did for me.”

“I think you have already done so,” said Jerry.
