"Oh yes," said the Idiot. "I'm in with several of 'em--'way in; so far in that I'm sometimes afraid I'll never get out. We're carrying a whole lot of wild-cats on margin for Billie Van Gelder, the cotillon leader. Tommy de Cahoots, the famous yachtsman, owes us about eight thousand dollars more than he can spare from his living expenses on one of his plunges into Copper, and altogether we are pretty long on swells in our office." "And do you mean to say those people invite you out?" asked the Bibliomaniac. "All the time," said the Idiot. "Just as soon as one of our swell customers finds he can't pay his margins he comes down to the office and gets very chummy with all of us. The deeper he is in it the more affable he becomes. The result is there are house-parties and yacht-cruises and all that sort of thing galore on tap for us every summer." "And you accept them, eh?" said the Bibliomaniac, scornfully. "As a matter of business, of course," replied the Idiot. "We've got to get something out of it. If one of our customers can't pay cash, why, we get what we can. In this particular case Mr. Reginald Squandercash had me down at Newport for five full days, and I know now why he can't pay up his little shortage of eight hundred dollars. He's got the money, but he needs it for other things, and, now that I know it, I shall recommend the firm to give him an extension of thirty days. By that time he will have collected from the De Boodles, whom he is launching in society, C. O. D., and will be able to square matters with us." "Your conversation is Greek to me," said the Bibliomaniac. "Who are the De Boodles, and for what do they owe your friend Reginald Squandercash money?" "The De Boodles," explained the Idiot, "are what are known as climbers, and Reginald Squandercash is a booster." "A what?" cried the Bibliomaniac. "A booster," said the Idiot. "There are several boosters in the Four Hundred. For a consideration they will boost wealthy climbers into society. The climbers are people like the De Boodles, who have suddenly come into great wealth, and who wish to be in it with others of great wealth who are also of high social position. They don't know how to do the trick, so they seek out some booster like Reggie, strike a bargain with him, and he steers 'em up against the 'Among-Those-Present' game until finally you find the De Boodles have a social cinch." "Do you mean to say that society tolerates such a business as that?" demanded the Bibliomaniac.
