Tripp, the Indianapolis trap shot, tells a "hard luck" poker story- He was sitting in a quiet game with a few of the trap shots one night at St. Louis. Everything had gone the other way with him, and the boys had been "doing something."
At last he got a handful of aces in the deal, and he said to himself, -“Here is where I get even." He started to bluff the others, but just at that moment Colonel Courtney, who up to that time had been a quiet onlooker, began to tell about a new Remington hanmerless gun that had but one trigger to pull both barrels. He got the other fellows so interested in that gun that they forgot all about the poker game, and Tripp got but five measly chips out of his four aces.”
“Rolla Heikes is now working his new single trigger Remington hammerless gun…”
