At the northern end of the Island the grass runs high, and there are no houses of any sort upon it. It reaches out into a rocky point, where it touches the still terribly swift eddies of Hell Gate, and its sharp front divides the water and directs it towards Astoria on the east and the city on the west. Hefty determined to walk off from the gang of workmen until he could drop into this grass and to lie there until night. This would be easy, as there was only one man to watch them, for they were all there for only ten days or one month, and the idea that they should try to escape was hardly considered. So Hefty edged off farther from the gang, and then, while the guard was busy lighting his pipe, dropped into the long grass and lay there quietly, after first ridding himself of his shoes and jacket. At six o'clock a bell tolled and the guard marched away, with his gang shambling after him. Hefty guessed they would not miss him until they came to count heads at supper-time; but even now it was already dark, and lights were showing on the opposite bank. He had selected the place he meant to swim for--a green bank below a row of new tenements, a place where a few bushes still stood, and where the boys of Harlem hid their clothes when they went in swimming. * * * * * At half-past seven it was quite dark, so dark, in fact, that the three lanterns which came tossing towards him told Hefty that his absence had been discovered. He rose quickly and stepped cautiously, instead of diving, into the river, for he was fearful of hidden rocks. The current was much stronger than he had imagined, and he hesitated for a moment, with the water pulling at his knees, but only for a moment; for the men were hunting for him in the grass. He drew the gray cotton shirt from his shoulders, and threw it back of him with an exclamation of disgust, and of relief at being a free man again, and struck his broad, bare chest and the biceps of his arms with a little gasp of pleasure in their perfect strength, and then bent forward and slid into the river.
