The sailor-men patronize the saloon kept by Portuguese Joe and his pretty wife and they put it over the simple dago in a peculiarly sailor-like fashion. They get their drinks and are not willing to pay. One day one of them carried the scheme so far as to get a drink on the nod and then to swallow the contents of the glass, into which he had poured a white powder that he carried with him. Feigning death, he was dragged out of the hotel by Joe, who was alarmed lest the police should appear and a dead drunk be found on the premises. So Joe put the man on the street. Several of the sailor-men habitues seeing the powder, tasted it and finding it only sugar, pointed out how Joe had been stung. Joe's little wife, like himself, conceived a suspicion of sailor-men in future and Joe thereafter was more careful of his naval guests.
