“Of course I can,” the Camera Chap agreed cheerfully. “We discussed many things—ranging all the way from Park Row to South America.”

“South America!” the correspondent exclaimed eagerly. “What did he have to say about that?”

Hawley’s eyes twinkled. “He asked me whether I’d ever been out there, and when I told him no he expressed great surprise, saying that I certainly ought to make it a point to go; that he felt sure I would find many interesting things to photograph in that part of the world.”

Hearing which Bates had a shrewd suspicion that the president had suggested some particularly interesting thing to photograph in some part of South America; but, although he was a past master in the art of extracting information from unwilling lips, his efforts failed to draw out the Camera Chap further along this line.

It was the president’s closing remark to Hawley which had compelled the latter to adopt this sphinx-like attitude.

“I will not pledge you to secrecy,” the chief executive had said. “I will merely urge you to be discreet, Mr. Hawley. I think I am able to estimate a man at first sight, and if I did not feel that you could be relied upon I would not have asked you to undertake this mission. You realize, of course, that in addition to the risk you will be running, a human life may depend upon your discretion.”

CHAPTER III.
PAXTON’S WARNING.

Inasmuch as the president had not pledged him to secrecy, the Camera Chap decided to take one person into his confidence regarding his visit to the White House. He knew that Tom Paxton, managing editor of the Sentinel, could be trusted, and there were reasons why Hawley felt that it was necessary to have him know the purpose of the undertaking on which he was about to embark. So he returned to New York that night, and arrived at the Sentinel office just as Paxton was closing down his desk with the intention of going home.

“Back so soon!” The boyish-looking managing editor greeted him, grinning. “I supposed it would take you at least a couple of weeks to tell the president all you know about how to run the ship of state. Seriously speaking, though, old man, I’m glad you’ve returned. I’ve got a little job for you up in Canada that needs your immediate attention. It——”

“I’m sorry, Tom,” the Camera Chap interrupted, “but I’m afraid I’ll have to ask you to hand that assignment to somebody else. I can’t touch it. I’ve got to have a couple of months’ leave of absence—to begin at once.”
