"Ha! Well, I'll have to change my opinion of the Boy Scouts, young man. I always took it for granted they were a sort of feeder to our regular army—playing soldier, you know. But if this is the kind of work they turn out, I don't know but I'll join myself."

George got out when they reached Chance's house, and helped the doctor carry the injured lad up the steps. "You needn't wait for me," he told the twins, "I'm going to stay a while."

"Come in and see me some time," Doctor MacArthur called back to Bob. "I want you to tell me more about your First Aid work! See you later, Mr. Bruce."

"Home, Jennings," said Bruce. "And be quick about it—I'm late."

Bob leaned back against the cushions and studied the grim, square-jawed face of the great man whom everybody was so anxious to please. So this was the way he looked at close range, this self-made, stubborn man of millions who always managed to bend every other man in his line of business to his own iron will! As he looked, Bob felt it was no wonder they all feared him—feared and followed.

For Bruce was the man who, more than all the others put together, was responsible for keeping Safety First work out of the mills in his line of business. Hundreds of men were killed and thousands injured every year in the great string of mills of which Bruce's was the head. Over and over it had been pointed out to him that the same Safety First work which had saved thousands of lives in other lines would save them in his line as well. But he was stubborn, iron-willed.

"You're wasting your time," was all he would say. "No theories or new-fangled notions in my mills."

Because Bruce said this, all the other mills hung back, too. There were reasons. They knew Bruce.

All this Bob knew from talks he had had with his father about the risks of working in Bruce's mills. He understood it better, now that he was face to face with Bruce himself.

All too soon, to the twins' way of thinking, the automobile drew up in front of Bruce's big stone house. The mill owner wasted no words. Jumping out, he waved his hand to the three, said to Jennings, "Take them wherever they want to go," and hurried up the walk.
