The ebb and flow of this tide of tenement dwellers is one of the momentous sights of Manhattan. At five in the morning the cross-town streets are almost deserted. On the Bowery the milk wagons and occasional trucks rattle northward in the false dawn. The intervals between the elevated trains are long. But the side streets are even more lifeless. Now and then shadows flit eastward—women, night workers, who scrub out the great Broadway office buildings. They would be shadows even in broad daylight. Towards six one begins to hear sharper, hurrying footfalls—coming westward. The tide has begun to flow. It grows in volume with the increasing light. The congested tenements have awakened; by six the flood is at its height. So dense is the rush that it is hard to make way against it, eastward. So fast the flow that the observer can scarcely note the faces. It is the backs which catch the eye and leave an impress on the memory. A man who walked like a soldier—upright—in that crowd would seem a monstrosity. Even the backs of the little children are bent. They seem to be carrying portly persons on their shoulders.

Then for close to twelve hours these side streets are almost deserted again—till the ebb begins. It is hard to decide which sight is the more awesome: the flow of humanity hurrying to its inhuman labor or the same crowd ebbing, hurrying to their inhuman, bestial homes.

But Yetta was not thinking of her fellow-workers. With the egoism of youth she was thinking of herself and the pain in her back. Harry had been right—the sweat-shop was killing her. There was a chance of escape and Life might never offer her another. She had come to the now-or-never place. Yetta was not a coward, she was only timid. And the bravery of timid people is sublime. For only a moment she hesitated in the dark hallway, below Goldfogle's Vest Company, and then with a smile—a fearless smile—on her lips she stepped out into the glare of the arc-light. Harry was waiting for her. She slipped her hand confidently into his arm.

"Say, Harry, to-morrow night, let's go to a ball."

"What?" he said, stopping short, to the surprise and discomfort of the home-rushing workers. "What?"

"Sure. I want some fun."

At last she had swallowed the bait! He could hardly believe his ears. But he was afraid to seem too eager. They were swept along by the hurrying crowd almost a block before he spoke.

"How about clothes?"

"I got some," she said. "I'll bring 'em to the shop and put 'em on there."
