"Who is that?"

"Mr. Carrhart, president of the company."

"They all look like miners to me. Put a shovel in their hands and they wouldn't be at all different from us. But we mustn't be standing here doing nothing. While we are here, let's take a look at the tracks over the chutes. There is a rail a little down at the heels. I shall have to report it as dangerous. Getting a car off here blocks the whole line. I wonder when that edge broke down. It was all right when I inspected it yesterday."

Steve took out his memorandum book and made a note of the condition of the rail for immediate report to the engineering department.

While the boys were thus engaged some of the party stood looking in their direction.

"Mr. Penton, who are those young men standing over yonder?" asked Mr. Carrhart.

"They are my track inspectors. They are a pair of likely young fellows. I'll wager there isn't a another pair of their age on the range that can equal them."

At this every one of the party turned to look at the Iron Boys, who, all unconscious of the attention they were attracting, were busy with their work.

"The chances are they do not even know you gentlemen are here, so attentive are they to their work."
