MOUNT BIGELOW.--This is a noble, grand, historical mountain, situated on the south side of Dead river, in Franklin county. For years it had been my strong desire to make the ascent, and in May, 1833, the desire was gratified. With six others, I left camp, and by evening reached Green's hotel, where we obtained lodgings for the evening. At early dawn, having supplied ourselves with lunch, tin cup and hatchet, we began the ascent on the northeast side. We soon passed the thrifty timber and aided our ascent of the craggy sides of the mountain by clinging to the shrubs that found roothold in the crevices of the rocks. It may not be amiss to say that we rested, that we rested frequently, for mountain climbing is no light work for those unaccustomed to it. While toiling wearily upward we found ourselves enveloped in mist, or a cloud, from which we soon emerged to find the heavens above us clear and bright, while leaden clouds shut out the landscape below. At twelve o'clock, noon, we were on the summit. By this time the clouds had been dispersed. The air was clear and cold and beneath us lay, as in a beautiful panorama, the lands and lakes of Maine. There are two peaks, about half a mile apart, between which is a valley and a small lake. From the highest of these peaks the view was magnificent. In the far north we imagined we saw Canada. The vast, northern expanse was all unoccupied save by a few farms at the foot of the mountain, and by a few camps of lumbermen, hunters and trappers. Looking to the northeast, we saw in the blue distance, glittering with snow drifts, Mount Katahdin. A little north of the divide line to Katahdin lay Moosehead lake, the largest, most beautiful lake in Maine.
