According to Hoyle.

"'Boxcar' Simmons, a tramp, represents himself as a mining millionaire in a small town. The population accepts him at his own valuation, and two of the town's 'slickers' make desperate efforts to 'take him for his roll.' One of their schemes is to sell him a worthless ranch, but he turns the tables on them by making them believe that the ranch is a veritable bed of silver ore, and then, after they buy it, he presents the major part of the proceeds to the girl who owns the place and with whom he had fallen in love." (Moving Picture World, 24 Jun 1922, p. 736.)
