at 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._

Chance Carter, lying helpless on the stone steps of Turner Hall, was

"Why doesn't that doctor come?"

"Surely he knows where we are, Betty?"

"Yes, I told him Turner Hall, and he said, 'Why, Turner Hall burned down
last night, little girl.' And I told him I knew it, and that we were
waiting right beside what was left of it."

"Hm-m-m! Something must have happened to him then; he could have walked
it in less time than this. If he doesn't come pretty soon, we'd better
call up the police department and have them send the ambulance. We can't
wait here much longer."

While they waited, an idea popped into Bob's head.

"Look here," he said, "somebody else is likely enough to get hurt here,
just the way Chance did. I believe we'd better put up a sign. I'll get
some paper from that store."

So Bob hurried around to the store and got some wrapping paper and nails
and borrowed a pencil and hammer. He worked fast, the shopkeeper looking
curiously over his shoulder while he lettered this sign:
