Through the fog I felt my way along by means of my compass. I no longer heard the bears, nor did I encounter one within the fog.

Experience has since taught me that these great beasts are as terror–stricken by this phenomenon as a landsman by a fog at sea, and that no sooner does a fog envelop them than they make the best of their way to lower levels and a clear atmosphere. It was well for me that this was true.

I felt very sad and lonely as I crawled along the difficult footing. My own predicament weighed less heavily upon me than the loss of Perry, for I loved the old fellow.

That I should ever win the opposite slopes of the range I began to doubt, for though I am naturally sanguine, I imagine that the bereavement which had befallen me had cast such a gloom over my spirits that I could see no slightest ray of hope for the future.

Then, too, the blighting, gray oblivion of the cold, damp clouds through which I wandered was distressing. Hope thrives best in sunlight, and I am sure that it does not thrive at all in a fog.

But the instinct of self–preservation is stronger than hope. It thrives, fortunately, upon nothing. It takes root upon the brink of the grave, and blossoms in the jaws of death. Now it flourished bravely upon the breast of dead hope, and urged me onward and upward in a stern endeavor to justify its existence.

As I advanced the fog became denser. I could see nothing beyond my nose. Even the snow and ice I trod were invisible.

I could not see below the breast of my bearskin coat. I seemed to be floating in a sea of vapor.

To go forward over a dangerous glacier under such conditions was little short of madness; but I could not have stopped going had I known positively that death lay two paces before my nose. In the first place, it was too cold to stop, and in the second, I should have gone mad but for the excitement of the perils that beset each forward step.

For some time the ground had been rougher and steeper, until I had been forced to scale a considerable height that had carried me from the glacier entirely. I was sure from my compass that I was following the right general direction, and so I kept on.

Once more the ground was level. From the wind that blew about me I guessed that I must be upon some exposed peak of ridge.

And then quite suddenly I stepped out into space. Wildly I turned and clutched at the ground that had slipped from beneath my feet.

Only a smooth, icy surface was there. I found nothing to clutch or stay my fall, and a moment later so great was my speed that nothing could have stayed me.

As suddenly as I had pitched into space, with equal suddenness did I emerge from the fog, out of which I shot like a projectile from a cannon into clear daylight. My speed was so great that I could see nothing about me but a blurred and indistinct sheet of smooth and frozen snow, that rushed past me with express–train velocity.

I must have slid downward thousands of feet before the steep incline curved gently on to a broad, smooth, snow–covered plateau. Across this I hurtled with slowly diminishing velocity, until at last objects about me began to take definite shape.

Far ahead, miles and miles away, I saw a great valley and mighty woods, and beyond these a broad expanse of water. In the nearer foreground I discerned a small, dark blob of color upon the shimmering whiteness of the snow.

"A bear," thought I, and thanked the instinct that had impelled me to cling tenaciously to my rifle during the moments of my awful tumble.

At the rate I was going it would be but a moment before I should be quite abreast the thing; nor was it long before I came to a sudden stop in soft snow, upon which the sun was shining, not twenty paces from the object of my most immediate apprehension.
