“He must be getting to be a regular high-flyer if he uses much wine,” remarked Frank when the four were on their way uptown. “What a fool he is with his money. He thinks that covers everything.”

“He’ll be foolish to take to drink,” returned Darry. “It has ruined many a rich young fellow, and he ought to know it.”

“I think Hockley would be all right if it wasn’t for the high opinion he has of himself,” came from Sam. “But his patronizing way of talking is what irritates. He considers nobody as important as himself. In one way I think he’d be better off if he was poor.”

“The family haven’t been rich very long—only eight or ten years, so I’ve heard,” said Mark. “Poor Hockley isn’t used to it yet. It will be a lesson to him to learn that there are lots of other rich folks in this world who aren’t making any fuss and feathers about it.”

In the morning came a message from Professor Strong, stating that he had arrived, and was stopping at the Hotel Manhattan. He added that he would see Mr. Robertson and Mr. Newton that morning, and would be at the service of the boys directly after lunch.

“Now we won’t lose much more time,” cried Frank. “I declare I wish we were to sail for Venezuela to-day.”

“I fancy the professor has a good many arrangements to make,” said Sam. “It’s quite a trip we are contemplating, remember.”

“Pooh! it’s not such a trip to Caracas,” returned Darry. “My father was down there once—looking at a coffee plantation.”

“A trip to Caracas wouldn’t be so much, Darry,” said Mark. “But you must remember that we are going further,—to the great lake of Maracaibo, and then around to the mouth of the Orinoco, and hundreds of miles up that immense stream. They tell me that the upper end of the Orinoco is as yet practically unexplored.”

“Hurrah! we’ll become the Young Explorers!” cried Darry, enthusiastically. “Say, I wonder if the professor will want us to go armed?”
