A man may win a purely local reputation, if only for eccentricity, by such means. But Mr. Jarvis's reputation was far from being purely local. Broadway knew him, and the Tenderloin. Tammany Hall knew him. Long Island City knew him. In the underworld of New York his name was a by-word. For Bat Jarvis was the leader of the famous Groome Street Gang, the most noted of all New York's collections of Apaches. More, he was the founder and originator of it. And, curiously enough, it had come into being from motives of sheer benevolence. In Groome Street in those days there had been a dance-hall, named the Shamrock and presided over by one Maginnis, an Irishman and a friend of Bat's. At the Shamrock nightly dances were given and well attended by the youth of the neighbourhood at ten cents a head. All might have been well, had it not been for certain other youths of the neighbourhood who did not dance and so had to seek other means of getting rid of their surplus energy. It was the practice of these light-hearted sportsmen to pay their ten cents for admittance, and once in, to make hay. And this habit, Mr. Maginnis found, was having a marked effect on his earnings. For genuine lovers of the dance fought shy of a place where at any moment Philistines might burst in and break heads and furniture. In this crisis the proprietor thought of his friend Bat Jarvis. Bat at that time had a solid reputation as a man of his hands. It is true that, as his detractors pointed out, he had killed no one--a defect which he had subsequently corrected; but his admirers based his claim to respect on his many meritorious performances with fists and with the black-jack. And Mr. Maginnis for one held him in the very highest esteem. To Bat accordingly he went, and laid his painful case before him. He offered him a handsome salary to be on hand at the nightly dances and check undue revelry by his own robust methods. Bat had accepted the offer. He had gone to Shamrock Hall; and with him, faithful adherents, had gone such stalwarts as Long Otto, Red Logan, Tommy Jefferson, and Pete Brodie. Shamrock Hall became a place of joy and order; and--more important still--the nucleus of the Groome Street Gang had been formed. The work progressed. Off-shoots of the main gang sprang up here and there about the East Side. Small thieves, pickpockets and the like, flocked to Mr. Jarvis as their tribal leader and protector and he protected them. For he, with his followers, were of use to the politicians. The New York gangs, and especially the Groome Street Gang, have brought to a fine art the gentle practice of "repeating"; which, broadly speaking, is the art of voting a number of different times at different polling-stations on election days. A man who can vote, say, ten times in a single day for you, and who controls a great number of followers who are also prepared, if they like you, to vote ten times in a single day for you, is worth cultivating.
