But it was a patience not without its breaks. Once he rose to look out front to make sure he had not miscalculated the distance of this factory from the river. Then after another period of waiting, he got thinking how much he might discover if he could get one glimpse into that far corner contiguous to that end of the rectangle where he had seen so many raw workers receiving the assistance of the night superintendent. There was a way of doing this of which he had not thought before. He had but to step outside, walk the length of the platform where the loading of shipments was going on, and look in at one of the great windows at the further end. But when he came to make the attempt, he found himself plunged into such a turmoil and the way so blocked by the loading of boxes and the backing up and driving off of horses that he retreated precipitately. Rather than encounter all this, he would await events from the inside. So he took his old seat again and for another half-hour listened to the thump of machinery and the squeak of a rusty elevator-brake which almost robbed him of thought. He was even inclined to doze, when he suddenly became aware of some change either in himself or in what lay about him. Had the machinery stopped? No, it was not that. The place seemed darker, yet it was still very light. With a restless move, he rose heavily and peered again into the court. Immediately it was evident what had occurred. The whole string of lights in the third story had been shut off, and now those of the middle story were following suit. Only the ground floor remained active with all its lights at the maximum, and every belt moving.
