"'Frank Hunter, Hotel dese Bugs.' Wal, that's a queer name for a tavern," he said. "I s'pose that's French for bugs?"

"It means that the big bugs stop there," said Frank, jocosely.

"Some of the big bugs are humbugs," said Jonathan, laughing grimly at his own wit.

When, after leaving Mr. Tarbox, Frank happened to examine his pockets, he drew out the two letters he had received. This puzzled him. What letter was that which he had given his Yankee friend, then? He could not tell. We are wiser. Sharpley had incautiously left on the table Craven's letter to him, and Frank had put it into his pocket, supposing it to be his. This it was which had passed into the possession of Mr. Tarbox.

Three days later Mr. Tarbox discovered the letter, and curiosity made him unscrupulous. He read it through, including the paragraph already quoted.

"By hokey!" he muttered. "That's queer. 'Should any accident happen, write at once.' He seems to expect an accident will happen. I'll bet that man is a snake in the grass. He's Frank's guardian, and he's got up some plot ag'in him. I always disliked that Sharpley. He's a skunk. I'll start for Switzerland to-morrow, and let the old plow go to thunder. I'm bound to look out for Frank."

Mr. Tarbox was energetic. He went to his lodgings, packed his carpet-bag, and early next morning started in pursuit of Frank and Sharpley.
