Hugh himself was agreeable. He intended, however, to see considerably more of Brother Lu in the immediate future, and expected to be able to gauge the fellow for what he really was. If he felt positive that there was a chance of his being an impostor, Hugh would consider it his duty to warn Mr. Hosmer, so that with the help of his wife they might catch the fellow in some sort of trap and expose him. Even though he did turn out to be the genuine article, Hugh felt that it would be a shame to have him hanging on the poor couple, and causing Matilda to work harder than ever to provide food, while possibly this able bodied tramp led a lazy sort of an existence. Accordingly the two boys strolled on, not having far to go in order to reach Hugh's home, where he could deliver the "sweet butter" he had gone out to the farm after. Just as Hugh anticipated, Thad "boiled over" as soon as they were out of earshot of the Hosmer cottage. Turning to look back he had seen the wretched hobo being tenderly escorted into the little dwelling, hardly more than a dove-cote in point of size, Matilda on one side, and her husband on the other; and the sight caused Thad to grit his teeth savagely. "I tell you it's a burning shame for that husky fraud to impose himself on that poor old couple the way he has done," grumbled Thad. "He's no more sick than I am. Didn't you see how he devoured all that food at a sitting? No man wasting away with consumption could stuff like that. And see how fat he is in the bargain; why, he'd make two of old Mr. Hosmer. Yet they are ready to take him in, feed him three meals a day, give him the best bed in the house, most likely, and for an indefinite time. Uh! thunder! it makes me furious just to think of it." Hugh was amused at seeing Thad act in this way, because it was so unlike his usual cool demeanor. Undoubtedly he was, as he had said, indignant from the crown of his head to the soles of his feet. "We'll both of us keep an eye on Brother Lu," remarked Hugh, "and try to learn his little game. You know he asked us to come over and see him, when he would keep his promise to tell us some thrilling yarns about his adventures in many lands." "Oh! I've no doubt the fellow has a slick tongue in his mouth, and can spin stories that haven't a particle of foundation except in his brain. He's no ignoramus, that's sure, and if he hasn't traveled in all those countries he's read about the same, and can talk everlastingly about things he imagines he's seen." "But all the while we'll be watching to trip him up, don't you see?" the other continued. "I'll set Matilda to fixing a trap or two that will settle the question about his being the man he says he is."
