"Yes, especially bacon rinds. Oh, Peter, come here, liebchen!" he called.
There was a sound of little light footfalls in the sand and Peter's wise gray face appeared in the doorway.
"Come here, sweetheart." The little burro crowded carefully around the table end until his head rested on Von Minden's shoulder. One by one, the old prospector handed up the bacon rinds and biscuits to him and Peter chewed sedately, flopping his ears back and forth.
"You are a good little boy. Now run along out," as the last rind disappeared and the burro trotted sedately out to browse industriously among the roots of the cactus.
"He really seems to understand," exclaimed Roger delightedly.
"He knows!" cried Von Minden. "And now, tell me about this solar heat. How are you going to harness it?"
Roger shook his head. "That I won't tell you now. But if you'll come back in three months' time, I'll show you the plant."
"You're afraid of me, eh? Well, perhaps that's a good idea. Afraid of me! Afraid of poor old Von Minden! There was a time when--ach! Well--perhaps you'll let me have a nap here on a bench. Then Peter and I'll go on up into the ranges."
"Make yourself at home," replied Roger.
Von Minden stretched his short length on the bench and closed his eyes. Before Roger had finished the dishes he was snoring. The little burro was standing in the shade of the living tent when Roger came out of the cook shelter. He looked pathetically small and thin and Roger, who had taken a great fancy to him, brought him a pail of water, and scratched his head and talked to him before going on into the tent. Here he was shortly absorbed in sorting his blue prints. He was studying the ground plan of the absorber, when an uncanny sense of being watched made him look over his shoulder. Von Minden, a sawed-off shot-gun aimed at Roger's back, was standing in the doorway.
"You will come down here and open up the world's best empire, will you--for America, eh? Not yet, my friend!" Von Minden's voice was husky and unsteady.
Roger did not move. In fact, he was incapable of moving.
"Look here," he began. Then as in a mist he saw Peter's gray head appear at his master's elbow and Peter himself, with his pack on his back, thrust his way past his master into the tent, just as Von Minden pulled the trigger. The shot seemed to hit everything in the tent but Roger. The mist before Roger's eyes turned to red and he made a spring for his guest. But Von Minden turned and fled, Peter after him, straight eastward across the desert toward the Coyote Range. They ran with surprising speed. Roger delayed long enough to get Ernest's rifle out of his trunk. By the time he had loaded it, after searching frantically several minutes for the box of cartridges, Von Minden and his little burro were far beyond rifle shot.
