"At last I began to look around, to determine what Mark's 'end of the river' meant. I soon discovered that he had run the boat away under a ledge of the mountain, and a dim light could only be seen in one direction. All else around us was impenetrable darkness. I took the paddle, and worked the boat in the direction of the light, and in a little while we emerged from beneath this overhanging mountain ledge, and again reached the current of the river, down which the boat was soon rapidly gliding. Mark now discovered that the 'end of the river' had not yet been reached, but he did not care to take charge of the boat again. "Shortly after this adventure we perceived that we were not to have smooth sailing all the way. The river began to grow rough, and the water ran over benches and ledges of rocks, and, in places, with great velocity, so much so that we narrowly escaped being 'broken up' on several occasions during this night's journey. We passed over a number of places that we would not have dared to risk in daylight, when we could have seen the danger. It seemed to grow worse and worse as we went on, when daylight warned us that it was time to tie up and hide, which we did, and, the day being warm and pleasant, we had a comfortable rest,--the best since our escape. "On the following night we came to a mill-dam, where the water, judging from the noise, poured over in great volume and force. We manoeuvred around for some time above it, not knowing what to do, but finally discovered what appeared to be an apron near the centre of the dam, and decided to risk running it. Accordingly, we rowed up-stream some distance to get under good headway, then turning the head of the boat down-stream, we bent to our paddles with all our might. We came down with the velocity of an express-train. What we supposed might have been an apron, was nothing but a break in the dam, and over it we shot like an arrow, shutting our eyes and holding our breath. In an instant after, we landed (luckily right side up) away below in the midst of the angry, foaming torrent, and plying our paddles right vigorously, and keeping the bow of our boat down-stream, we rode out safely, but then and there 'swore off' on running mill-dams in the night.
