"He looks like an American horse," said Obed, with satisfaction, "and maybe he is one, stolen from the Texans. He'll carry one of us over many miles of sand and cactus, and he'll be none the worse for it. But he needs a friend. Horse was not made to live alone. It's my sympathy for him as much as the desire for another mount that drives me to the theft we contemplate." Ned laughed and lolled on the grass which was now dry. "Yon stay here with Bucephalus or Rosinante or whatever you choose to call him," continued Obed, "and I think I'll cross the hills, and see if Cos is near. If we're going to capture a horse, we must first know where the horse is to be found." "Suppose I go along, too." "No, it would be easier for the Mexicans to see two than one, and we shouldn't take unnecessary risks. Be sure you stay in the valley, Ned, because I want to know where to find you when I come back. I've an idea that the Mexican army isn't far, as we wound around a good deal during the storm and darkness, and covered no great distance, if it were counted in a straight line. At least I think so." "You'll find me here." Obed went toward the east, and Ned continued to make himself comfortable on the grass, which was so long and thick that it almost hid his body. But it was truly luxurious. It seemed that after so much hardship and danger he could not get enough rest. He felt quite safe, too. It would take a careful observer to see him lying there in the deep grass. It was warm and dry where he lay, and the little valley was well hemmed in by forest in which crotons, mimosas, myrtle oaks, okote pine and many other trees grew. Some had large rich blossoms and he admired their beauty. His eyes wandered back from the forest to their new friend, the horse. Besides being an animal of utility the horse added to their comradeship. Ned felt that he still had a friend with him, although Obed was away. Obed had spoken truly. It was a fine horse, a bay, tall, strong and young, grazing with dignified content, at the end of a lariat about forty feet in length. Ned watched the horse idly, and soon he saw him raise his head, stand perfectly still for a moment or two, and then sniff the wind. The next instant an extraordinary manifestation came from him. He whirled about and galloped so fast to the end of his tether that he was thrown down by the sharp jerk. He regained his feet and stood there, trembling all over. His great eyes were distended. Ned had never before seen such a picture of terror.
