"They needed men on both sides of the stockade to do that," said Colonel Preston, "and those whom we saw, climbed over, so as to give assistance."

"That's the most sensible idee that's been put forward," replied Jo Stinger, "and I shouldn't be s'prised if you was right; but somehow or other——"

"By gracious! I smell smoke sure as yo's bo'n!"

Blossom Brown gave several vigorous sniffs before uttering this alarming exclamation, but the words had no more than passed his lips, when every man knew he spoke the truth.

There was smoke in the upper part of the block-house, and though it could not be seen in the darkness, yet it was perceptible to the sense of smell.

Consternation reigned for a few minutes among the garrison, and there was hurrying to and fro in the effort to learn the cause of the burning near them.

The most terrifying cry that can strike the ears of the sailor or passenger at sea is that of fire, but no such person could hold the cry in greater dread than did the garrison, shut in the block-house and surrounded by fierce American Indians.

The first supposition of Colonel Preston was that it came from the roof, and springing upon a chair, he shoved up the trap-doors, one after the other, to a dangerously high extent. But whatever might have happened to the other portions of the structure, the roof was certainly intact.

The next natural belief was that it was caused by the fire on the hearth in the lower story, and Colonel Preston and Blossom Brown made all haste down the ladder. Blossom, indeed, was too hasty, for he missed one of the rounds and went bumping and tumbling to the floor, where he set up a terrific cry, to which no attention was paid amid the general excitement.

"Here it is! Here's the fire!" suddenly shouted Ned Preston, in a voice which instantly brought the others around him.
