Billy Boyle's succumbed to his love for the race-track and the abuse of his credit-check system. Field has mentioned gamblers as among the patrons of the place. After midnight they were his most liberal customers. Winning or losing, their appetites were always on edge and their tastes epicurean. Nothing the house could afford was too good for them, and, while Charlie was on deck, what the house could afford was good enough for them, whether they thought so or not. During the '80s Chicago was a gamblers' paradise. Everything was run "wide open," as the saying is, under police regulation and protection, and Billy Boyle's was in the very centre of the gambling district. If Billy had been paid cash, and could have been kept away from the race-tracks, he would have grown rich beyond the terrors of the sheriff. While the gamblers were winning they supped like princes and paid like goldsmiths. When they were losing their losses whetted their appetites, they ate to keep their spirits up, and Billy's spindles were not long enough to hold their waiters' checks. In flush times a goodly percentage of these checks were redeemed, but the reckoning of the bad ones at the bottom grew longer and dirtier and more hopeless, until it brought the sheriff. We of the Morning News--Field, Stone, Ballantyne, Reilly, and I--frequented Boyle's until the war which the paper waged unceasingly upon the league between the city administration and the gamblers brought about a stricter surveillance of gaming, and we came to be regarded by our fellow-guests as interlopers, if not spies, upon their goings in and out. Neither Boyle nor the ever faithful Charlie ever by word or sign intimated that we were _personæ non gratæ_, but the atmosphere of the place became too chilly for the enjoyment of late suppers. I have devoted so much space to Billy Boyle's because for several years Field found there the best opportunity of his life "to study human nature" and observe the "ambitions, hopes, purposes, and eccentricities" of his fellow-man.
