“But, Mr. Gordon,” protested Bob, “I don’t want you to get a horse for me! I’d rather have a job. Isn’t there something I can do out at the oil fields? I’m used to looking out for myself.”

“Look here, young man,” came the reply with mock severity, “I thought I told you you had a job on your hands looking after Betty. I meant it. I can’t go round on these inspection trips unless I can feel that she is all right. And, by the way, have you any objection to calling me Uncle Dick? I think I rather fancy the idea of a nephew.”

Bob, of course, felt more at ease then, and Betty, too, was pleased. The boy found it easy to call Mr. Gordon “Uncle Dick,” and as time went on and they became firmer friends it seemed most natural that he should do so.

They were approaching the oil fields gradually, the road, which was full of treacherous ruts, being anything but straight. Whenever they met a team or another car, which was infrequently, they had to stop far to one side and let the other vehicle pass. Betty was much impressed with her first near view of the immense derricks.

“What a lot of them!” she said. “Just like a forest, isn’t it, Uncle Dick?”

Her uncle frowned preoccupiedly.

“Those are not our fields,” he announced curtly. “They’re mostly the property of small lease-holders. It is mighty wasteful, Betty, to drill like that, cutting up the land into small holdings, and is bound to make trouble. They have no storage facilities, and if the pipe lines can’t take all the oil produced, there is congestion right away. Also many of the leases are on short terms, and that means they’ve the one idea of getting all the oil out they can while they hold the land. So they tend to exhaust the sands early, and violate the principles of conservation.”

They were following the road through the oil fields now, and presently Mr. Gordon announced that they were on his company’s holdings. At the same time they saw a column of dense black smoke towering toward the sky.

“There’s the fire!” cried Betty. “Do hurry, Uncle Dick!”

Obediently the little car let out a notch, and they drew up beside a group of men, still some distance from the fire.
