"There goes the other horse," cried Miss Elting, as a crash and a great
splash for the moment cut short their conversation. Janus uttered a
yell of triumph.

"We got 'em both free!" he shouted.

"That's what," agreed Jim. "We'll pull the carry-all ashore next."

"I am afraid we won't have time. The fire is almost too near for
comfort now," said Harriet. Then she darted back to the carry-all to
secure a blanket that she recalled had been laid over the back of the
front seat of the vehicle, and which had been forgotten when removing
the other things. Reaching the wagon, she decided to take the cushions
also. Then Harriet made a final search of the wagon to be sure that
nothing of value had been left. The carry-all had been well stripped.

The girl sprang out, casting a quick glance overhead, when she
discovered, to her dismay, that the flames were already at work, they
having rapidly eaten their way along the ridge of the bridge.

"Gracious! I must get out of here and without a moment's loss of
time," she cried.

"Hurry!" bellowed the voice of the guide. "We haven't time to save the
carry-all. Get out from under. The bridge is going to fall."

As Harriet made a dash toward safety the burned end of the bridge fell.
There was a rending noise as the weakened girders gave way under the
weight of the bridge. A shower of sparks and flame shot into the air.
