The "Human Dog" was but a clever variation of the "Crust-Thrower" --the beggar who tosses a dirty crust of bread into the gutter when no one is looking and then falls upon it with a cry of fierce joy. These "crust-throwers" have plied their trade for over six hundred years and were known in England and Flanders long before the discovery of America. Gottlieb was very shrewd at devising schemes that came just within the law and used to amuse himself by so doing in his leisure moments. One of the best--the idea which he sold for three hundred dollars and which is still being used in New York, Chicago, and elsewhere--is the following: An old man, with a square of plate glass in a newspaper and a bundle of glass-cutter's tools by his side is seen sitting dejectedly on a curb with his head in his hands. He has no coat and the icy wind blows through his straggling locks of gray hair--a pathetic picture. He seems utterly discouraged, but no word of complaint passes his lips. Presently a well-dressed woman approaches and her pity is instantly aroused. She accosts him, and the aged one informs her in a faint voice that he works in Harlem and has been sent by his boss to set a pane of glass on Varick Street; but not knowing exactly where Varick Street is, he has got off the elevated at Fifty-ninth Street and finds that he is still several miles from his destination. What woman, unless she had a heart of granite, would not be moved by such a tale! She opens her purse and pours its contents into his lap; for it is a psychological truth that, if you can once get a woman up to the point of giving anything, she will give all that she has. How often have I seen these old men--the children of Gottlieb's brain--sitting patiently and silently on the streets! And how often have they paid us handsome fees to get them out of the "jug"! In this catalogue of clients I must not forget "Banana Anna," who recently, I am sad to say, met her Waterloo. Anna was a lady so peculiarly gifted by the Almighty that she was able at will to simulate a very severe physical mishap. I shall not describe with any greater degree of particularity what her precise affliction was, save to say that if genuine it would have entitled her to the sympathy and generosity of mankind. It was the kind of thing that might easily result from a fall; but which, in fact, under ordinary circumstances gave her no inconvenience whatever.
