Presently he gains upon the runaway so that he can detect the white feet pattering along the red bricks, rising and falling quite noiselessly. He ejects imprecations upon his own stout boots, which not only fail to fasten themselves firmly to the slippery pavements, but continually betray by their noisy splashing his exact position. As they pass the next lamp, Mr. Smithers sees plainly enough that the end is near. The fugitive touches the ground with only the balls of his feet, as if each step were torture, and expels his breath with unceasing violence. He does not gasp or pant,--he groans. Just at the bend in Leverett Street, leading to the bridge, there is a dark and half-hidden aperture among the ill-assorted houses. Into this, as a forlorn hope, the fugitive endeavors to fling himself. But the game is up. Here, at last, he is overhauled by Mr. Smithers, who, dropping a heavy hand upon his shoulder, whirls him violently to the ground. Having accomplished this exploit with rare dexterity, he forthwith proceeds to set the captive on his feet again, and to shake him about with sprightly vigor, according to established usage. Mr. Smithers next makes a rapid but close examination of his prize, who, bewildered by the fall, stares vacantly around, and speaks no word. He was a young man, apparently about twenty years old, with nothing peculiar in appearance except an unseasonable deficiency in clothing. Coat, waistcoat, trousers, boots, hat, had he none; shirt, drawers, and stockings made up his scant raiment. Mr. Smithers set aside the suspicion of burglary, which he had originally entertained, in favor of domestic disorder. The symptoms did not, to his mind, point towards delirium tremens. Suddenly recovering consciousness, the youth was seized with a fit of trembling so violent that he with difficulty stood upright, and cried out in piteous tones,-- "For God's sake, let me go! let me go!" Mr. Smithers answered by gruffly ordering the prisoner to move along with him. By some species of inspiration--for, as the era of police uniforms had not then dawned, it could have been nothing else--the young man conceived the correct idea of the function of his custodian, and, after verifying his belief, expressed himself enraptured. All his perturbation seemed to vanish at the moment. The affair was getting too deep for Mr. Smithers, who could not fathom the idea of a midnight malefactor becoming jubilant over his arrest. So he gave no ear to the torrent of excited explanations that burst upon him, but silently took the direct route to the station.
