"A loiterer in the streets of New York," the beggar explained, "picks up knowledge not to be had in any other way. Knowledge is power."

"Then you don't have to beg, don't have to pose, don't have to do anything you don't want to do?"

"Oh, yes, I do. I have to crawl while others walk. I have to wait and procrastinate, where another might rush in and dare."

Without a word, Barbara stepped eagerly forward to the rough model that she had made of his head, and once more attacked her inspiration with eager hands.
