"You'd better manage this part," he said in a low tone. "My arm's not strong enough yet to be depended on in such ticklish matters. I tried it to-day with my gun, and it's mighty near as steady as ever for shooting, but I won't risk it on this." They rode into the Mexican's garden and Ellhorn stood with the extra horse under the drooping branches of the peach tree. They listened and heard the sound of a soft whistling in the _patio_, as if some one were idly walking to and fro. "That's him!" Ellhorn whispered excitedly. "That's what I told him to be doing at just this time! He's listening for us!" Ellhorn whistled softly several bars of the same air, which were at once repeated from within. Tuttle rode beside the wall and threw over it the end of his lariat. He waited until the whistling ceased, and then, winding the rope around the pommel, he struck home the spurs and the horse leaped forward, straining to the work. It was a trained cow-pony, Mead's own favorite "cutting-out" horse, and it answered with perfect will and knowledge the urging of Tuttle's spurs. With a soft "f-s-s-t" the rope wore over the top of the wall and Mead's tall form stood dimly outlined behind the battlement of cactus. He untied the rope from his waist, threw it to the ground, and with foot and fist thrust aside the bristling, sharp-spined masses, dropped over the outer edge, hung at full length by his hands for an instant, and landed in the soft earth at the bottom. They heard his name called inside the _patio_. It was the guard, who had just missed him. As they quickly mounted there came over the wall the sound of hurrying feet and the rapid conference of excited voices. Mead shot his revolver into the air and Ellhorn, lifting his voice to its loudest and fullest, sang: "Come ope the west port and let us go free To follow the bonnets of Bonnie Dundee!" "Whoo-oo-oo-ee-ee!" Spur met with flank and the three horses bounded forward, over the fence of the Mexican's garden, and up the street at a breakneck gallop. They clattered across the _acequia_ bridge and past Delarue's place, where Mead, eagerly sweeping the house with a sidewise glance, had a brief glimpse of a brightly lighted room. Instantly his memory went back, as it had done a thousand times, to that day, more than a year before, when he had stood at the door of that room and had first seen Marguerite Delarue. As they galloped up the street the vision of the room and of the girl came vividly back--the inviting, homelike room, with its easy-chairs, its pictures and shaded lamps, its tables with their tidy litter of papers and fancy work, its pillowed lounges, and deep cushioned window-seats, and the tall, anxious-eyed girl with the sick child in her arms, held close to her breast. Unconsciously he turned his head, possessed for the moment by the vision, and looked back at the dark mass of the house and trees, lighted by the one gleaming window.
