Dick now followed the trail of his lost companions at a rapid pace, yet not so rapidly as he might have done, being averse to exhausting his good dog and his new companion. Each night he encamped under the shade of a tree or a bush when he could find one, or in the open prairie when there were none, and, picketing his horse to a short stake or pin which he carried with him for the purpose, lit his fire, had supper, and lay down to rest. In a few days Charlie became so tame and so accustomed to his master's voice that he seemed quite reconciled to his new life. There can be no doubt whatever that he had a great dislike to solitude; for on one occasion, when Dick and Crusoe went off a mile or so from the camp, where Charlie was tied, and disappeared from his view, he was heard to neigh so loudly that Dick ran back, thinking the wolves must have attacked him. He was all right, however, and exhibited evident tokens of satisfaction when they returned. On another occasion his fear of being left alone was more clearly demonstrated. Dick had been unable to find wood or water that day, so he was obliged to encamp upon the open plain. The want of water was not seriously felt, however, for he had prepared a bladder in which he always carried enough to give him one pannikin of hot sirup, and leave a mouthful for Crusoe and Charlie. Dried buffalo dung formed a substitute for fuel. Spreading his buffalo robe, he lit his fire, put on his pannikin to boil, and stuck up a piece of meat to roast, to the great delight of Crusoe, who sat looking on with much interest. Suddenly Charlie, who was picketed a few hundred yards off in a grassy spot, broke his halter close by the headpiece, and with a snort of delight bounded away, prancing and kicking up his heels! Dick heaved a deep sigh, for he felt sure that his horse was gone. However, in a little Charlie stopped, and raised his nose high in the air, as if to look for his old equine companions. But they were gone; no answering neigh replied to his; and he felt, probably for the first time, that he was really alone in the world. Having no power of smell, whereby he might have traced them out as the dog would have done, he looked in a bewildered and excited state all round the horizon. Then his eye fell on Dick and Crusoe sitting by their little fire. Charlie looked hard at them, and then again at the horizon; and then, coming to the conclusion, no doubt, that the matter was quite beyond his comprehension, he quietly took to feeding. Dick availed himself of the chance, and tried to catch him; but he spent an hour with Crusoe in the vain attempt, and at last they gave it up in disgust and returned to the fire, where they finished their supper and went to bed.
