"I suppose," Frank Shaw said, at the end of a long pause in the conversation, "I suppose Ned and the others are out over the Andes by this time."

"No," replied Jack. "I heard from Jimmie by wire today, and they are still in Frisco, and likely to remain there nearly a week longer."

"If the airship was only large enough!" sighed Harry.

"We might still get there in time!" Frank suggested, eagerly.

"The Nelson wouldn't carry us if we were there," Jack exclaimed, in a disgusted tone. "I wish the Black Bear had wings! Say, wouldn't that be a peach? We could run over to Paraguay and scare the life out of the boys!"

"What good would it do if she had wings?" demanded Frank. "She is in storage at Portland, Oregon."

"No," replied Harry Stevens, whose father, a noted maker of automobiles, had presented the motor-boats to his son, "I ordered the boats sent on here the day after we left the coast. We can take a trip up the Hudson, anyway."

Jack walked thoughtfully around the room for a moment and then turned back to the others, looking moodily out of a window.

"I've got it!" he shouted, slapping Frank on the back.

"I should say you had!" remarked Frank. "What do you take for it?"
