"Not do any harm," he repeated, as though hardly able to grasp the meaning of the words Frank spoke; then his brown face lighted up with a grim smile. "White boys good; Havasupai glad him not take horse. Bad Indian! But not always that way; him carry speaking paper tell how make good," and he thumped his breast as he said this. Again did Bob's eyes seek the face of his chum in a questioning manner. Frank, having been raised amid such scenes, could more readily understand what the Moqui meant when he referred to certain things which Bob had never heard mentioned before. "He means that he's got a letter of recommendation along with him, written by some tourist, I reckon. Perhaps this old fellow may have found a chance to do some one a good turn. He may have run across a greenhorn wandering on the desert; saved a fellow who had been stabbed by the fangs of a viper from the Gila; or helped him to camp when he broke a leg in climbing around the Grand Canyon." "Oh! I see what you mean, Frank; that this party wrote out a recommendation to all concerned, stating that in his opinion Havasupai was a fine fellow, and worth trusting. But then that was before he got into this trouble at this village. If he's a fugitive from justice at the hands of his own tribe, such a paper isn't worth much, I guess." "No more it isn't," agreed Frank. "But all the same he means to stick us with it," chuckled Bob; "for you can see he's got his hand in his shirt right now, as if searching for something so valuable that he won't even carry it in his ditty bag." "That's right, Bob." "And now he's got in touch with that old letter," grunted Bob. "I suppose we'll just have to read it to please him." "You can if you care to," remarked Frank. "As for me, I'm that sleepy I only want a chance to crawl back into the tent, and take up my interrupted nap where it broke off." "But good gracious! do you really mean it?" exclaimed the puzzled Bob. "Why not?" demanded his chum. "And leave him loose here, with the horses close by?" Bob went on, aghast. At that Frank laughed a little. "Well," he said, drily; "so far as the horses are concerned, I reckon our old friend Havasupai will go a long way on foot before he ever tries to steal a promising looking pony again. As long as he lives he'll remember how it feels to get a pair of hoofs fairly planted against his back. So long, Bob. Tell the old fraud he can lie down anywhere he pleases, and share our breakfast in the morning." "That's the way you rub it in, Frank; returning evil with good," the Kentucky boy remarked. "But since you want me to take him in hand, I'll be the victim, and read his letter of recommendation, though I can already guess what it will say."
