Instantly the figure, with a jerk and a catlike squirm, tried to break away, but David's arms, gripped about its body, held it fast. Then it resumed its choking embrace of David's neck. The sack about his head was heavy; the air hardly came through it. He began to gasp. He tried frantically to throw the figure off, but it held its place. Then one hand fell upon a mop of hair. He clutched it and pushed fiercely upward. The embrace broke, and two fists began to beat his face through the sack. An instant later David managed to scramble to his feet and throw off the sack—and he then saw that the writhing, kicking figure he had captured reached midway between his waist and shoulders.

His right hand still fastened in his captive's hair, David lighted the gas. There, at the end of his arm, was a boy with the figure of fourteen and the face of twenty. His clothes, baggy and torn, were for the latter age; the trousers were rolled up six years at the bottom. The face was wrinkled in a scowl, and the eyes gleamed defiance. He was panting heavily. On the floor lay what David had thought was a sack; it was his own overcoat.

"Why you're nothing but a boy!" David cried.

"A boy! Nuttin'! If I'd been in form, I'd 'a' showed you!"

David locked the door, cut off escape by standing before the window, and disentangled his fingers from the boy's locks. He then saw that the boy's dirty yellow hair flowed upward from his forehead in a cow-lick.

The boy put his hands in his pockets and continued his defiant stare.

"Now, sir, what were you doing in here?" David demanded.

"What you t'ink?" the boy returned coolly. "You t'ink I come to collect de rent?"

"You tried to steal my coat."

"Gee, you're wise! How'd you guess it?"
