"I didn't realize, of course, what your errand was," said M. Desplaines in reply, "till Mr. Barr arrived here in his yacht the other day and informed me that you had stolen a cache of ivory belonging to him and asked my aid to help in capturing you. I had no means of disproving his story so I lent him the steam launch, but I see now by his action in hastening to the yacht that he is, as you say, the real thief."

Hastily Frank told a part of their adventures and if he had had any remaining doubt of the boys' sincerity the consular agent was soon convinced of the truth of their story and of the villainy of Barr.

"I can get you some gasoline—," he said. "A merchant here in town recently bought a launch and as the freight boats do not touch in here often he has laid in a large supply of the fuel. I have no doubt that at my request he will be glad to sell you as much as you require."

This was good news indeed, and the boys hastened round to the house of M. Desplaine's friend. To their unspeakable regret, however, he was absent on a fishing expedition in his launch.

"If that isn't tough luck," exclaimed Billy disgustedly, "what can we do now?"

"Wait till he gets back or else break into his warehouse," said Harry.

"We cannot commit burglary," said Frank, "we shall have to wait."

M. Desplaines invited the party to lunch at his house but as may be imagined they did not eat much. Each was in too much of a hurry to ascertain if the fisherman had not returned. Immediately the meal was dispatched, therefore, they hastened out into the street and here they encountered a strange scene.

A score or more of rough-looking characters had just landed from four ship's boats that lay moored at the small wharf. They had joined forces with the crew of the launch that had aided in the ivory hunt and all were bent on a carouse. The boys were hardly able to speak from excitement when they read on the stern of each of the boats the words "Brigand N. Y."

"Those boats are from Barr's yacht," cried Frank.
