We therefore separated, agreeing upon a signal of two shots from whichever of us had the skill or fortune to discover the outlet. The other canoe faded into the mist below the islands while we paddled slowly toward the gray green shores opposite. When presently we were all alone, I was filled, somehow, with the feeling that must have come over those old Canadian voyageurs who were first to make their way through the northlands, threading the network of unknown waters. I could not get rid of the idea that we were pioneers in this desolate spot, and so far as sportsmen were concerned, it may be that we were. Chapter Twelve _The lake is dull with the drifting mist,_ _And the shores are dim and blind;_ _And where is the way ahead, to-day,_ _And what of the path behind?_ Chapter Twelve Along the wet, blurred shore we cruised, the mist getting thicker and more like rain. Here and there we entered some little bay or nook that from a distance looked as if it might be an outlet. Eventually we lost all direction and simply investigated at random wherever any appearance seemed inviting. Once we went up a long slough and were almost ready to fire the signal shots when we discovered our mistake. It seemed a narrow escape from the humiliation of giving a false alarm. What had become of the others we did not know. Evidently the lake was a big one and they might be miles away. Eddie had the only compass, though this would seem to be of no special advantage. At last, just before us, the shore parted--a definite, wide parting it was, that when we pushed into it did not close and come to nothing, but kept on and on, opening out ahead. We went a good way in, to make sure. The water seemed very still, but then we remembered the flatness of the country. Undoubtedly this was the outlet, and we had discovered it. It was only natural that we should feel a certain elation in our having had the good fortune--the instinct, as it were--to proceed aright. I lifted my gun and it was with a sort of triumphant flourish that I fired the two signal shots. It may be that the reader will not fully understand the importance of finding a little thing like the outlet of a lake on a wet, disagreeable day when the other fellows are looking for it, too; and here, to-day, far away from that northern desolation, it does not seem even to me a very great affair whether our canoe or Eddie's made the discovery. But for some reason it counted a lot then, and I suppose Del and I were unduly elated over our success. It was just as well that we were, for our period of joy was brief. In the very instant while my finger was still touching the trigger, we heard come soggily through the mist, from far down the chill, gray water, one shot and then another. I looked at Del and he at me.
