"The flats" was the largest building on their home street. Built on the corner, in the shape of a huge, four-storied, red brick "C," it was really composed of a number of apartments with separate entrances with a common, cement-paved inside court on which the back porches fronted. The basements were given over to boiler rooms, laundry tubs, and storerooms, linked by long, twisting, badly lighted corridors which formed excellent hiding places for the boys in time of pursuit.

The gang gathered noisily just off the corner and waited for victims. A gray-haired, poorly clad woman shuffled past. Sid raised his arm. Silvey whispered a protest. "That's old lady Allen. Has the rheumatism. Leave her alone."

John broke into a gleeful chortle. "Look what's coming, fellows."

The cause of his exultation was a callow youth of sixteen, whose father had met with a sudden wave of prosperity and was now trying to sell his rather modest home that he might move to a more exclusive neighborhood. The son was inclined to patronize old acquaintances and affected a multitude of expensive tailored clothes and a light cane. John eyed the gray, immaculately pressed suit appreciatively and let fly.

The boy wheeled in surprise, then stooped to pick up his hat.

"You fellows had better cut that out," he blustered, as he straightened the soft, felt brim.

"Who's going to make us?" Silvey jeered, as his cucumber hit the neat lapel.

"Just do that again. I'll show you."

A volley of the juicy missiles greeted his words. He charged upon the boys, who fled to the haven of the darkest of the corridors and took refuge in an empty outer storeroom. There they barricaded themselves and awaited his coming.

"Ya-a-ah," John taunted, as he heard heavy breathing through the door. "What'll you do now?"
