For an instant it seemed as if the weight of a ton was pressing upon my bent back, and then I heard a dull, muffled sound, as if some heavy body had fallen into the snow on the outside.

The strain upon me was lessened wonderfully, and my heart leaped with joy and gratitude as the dear boy whispered excitedly:—

“We have thrown off the top log, Dicky Dobbins, and unless there be a sentinel outside who has heard the timber fall, we shall be free from this pen as soon as you are minded to make the venture.”

He leaped down from my back, and, grasping both his hands to show my gratitude for his gallant and wondrous effort, for it was wondrous in view of his slight body, I replied:—

“We’ll count thirty, Alec, and if by that time no alarm is given, it is for us to make good an escape, taking the chances of losing our way in the driving snow upon the ice, rather than remain here; for now has come the time when we may save Presque Isle from falling into the hands of the enemy.”

CHAPTER III.
THE ESCAPE.

How it may have been with Alec Perry while we stood inside that pen, listening eagerly, and yet fearing lest we might hear something, I know not. As for myself, it was as if the blood in my veins was at boiling point, and I could hardly breathe because of the sense of suffocation which had come upon me.

At first I began to count as rapidly as it was possible to speak the figures in my thoughts, and then came the knowledge that by hastening the time ever so little I might be destroying our chances for escape.

In case the fall of the timber had been heard, and one of the soldiers came out to learn the cause of the noise, it was possible he would fail to observe what had been done, for the snow was so light that the log must be concealed from view in its frosty bed.

I say again, it was possible, even probable, that one or more of the Britishers might come out and yet fail to detect what we had done; but if Alec and I should begin the attempt a few moments too soon, all would be lost. Better waste half the night than try to gain sixty seconds of time, and in the doing cut ourselves off from all hope of gaining liberty.
