"All ready, sir," he announced imperturbably.

With half-a-dozen strides his master reached the car; in as many seconds the powerful engine was throbbing. The screaming horn gave warning, the quiet herds in the valley heeded, lifted their heads and stood at attention, ready to scamper this way or that as need arose. The wheels turned, the car jolted over the inequalities presented by the field, swerved sharply, turned, gathered speed and whizzed away toward the valley road.

Three times before they shot back into the mouth of Blue Bird Cañon the mechanician fancied that his employer had spoken; each time listening, he failed to catch any other sound than that made by the engine and speeding wheels. Once he said, "Sir?" and got only silence for an answer.

He shook his head and wondered; it was not Packard's way to mumble to himself. And again, ready to jump for his life as the big car took a dangerous turn, his eyes glued to the sheer bank a few inches from the singing tires, he caught a sound through the blast of the sparton which surely must have come from the driver's lips.

"What say?" yelled Guy Little.

No answer. He caught a fleeting glimpse of a farmer at the head of his two plunging horses where the man had hurriedly got them out of the way and up the flank of the mountain. They raced on. And again, surely Packard had said something.

"Talkin' to me?" called Little.

Then, for just a wee fraction of a second, Packard drew his eyes from the road and his look met the mechanician's. The old man's eyes were shining strangely.

"Damn it, Guy Little," he boomed out boisterously, "can't a man laugh when he feels that-away?"

And it suddenly dawned upon Guy Little that ever since they had left Ranch Number Ten the old man had been chuckling delightedly.
