"It's this leg." He touched his left, just below the knee. "I felt something break when the wall hit me. Perhaps the other's broken, too—I don't know."

Very carefully Bob ripped the clothing from the injured leg. Then he put one hand gently on the spot Chance touched, and the other hand just below it, and lifted the leg slightly. There was enough movement at the broken point so that there could be no doubt. The other leg proved to be badly bruised, but not broken.

Bob carefully moved the broken leg back into the same position as the right one and piled his coat and George's around it so it would stay in shape. He brought the suffering boy some water in his hat, and the three waited for the doctor.

"He said he'd come right away," reported Betty, hurrying back from the telephone. "But, Bob, it isn't safe to stay down there—no telling when that other chunk of the wall may fall on all three of you. Shall I try to push it over from the inside?"

"Goodness, no, Betty! Keep as far away from it as you can. Well, we'll have to get him out of here, some way. You run back to that first store, please, and get half a dozen good strong strips of cloth about a foot wide and two or three feet long—anything that will do to tie his leg up to the splints. George, you bring over a few of those pieces of flooring that are not too badly charred to use for splints. There!"

He laid a long piece of flooring along Chance's left side, from below his foot clear to his armpit, and chose a shorter board for the inside splint. He arranged the two coats so that they would pad the broken leg where the boards came up against it, and tied the splints firmly, but not tightly, in place. Then Bob slowly gathered his groaning friend in his arms.

"Sorry to hurt you, old fellow, but we've got to get you out of here. You take his legs, George,—gently, now. So! We can climb out along that cave-in on the street side if we take it easy. Up we go!"

Better be safe than sorry.—Sure Pop
