Umbagog Lake, from which the Androscoggin takes its rise, from the construction of its shores, acts as a regulator upon the height of the water. When the Megalloway rises, it flows into the Androscoggin, and raises its waters, so that they run back into the lake for the distance of two miles, having the appearance of a river running back to its source. The Androscoggin rises from the western side of the lake, and here is a sluggish stream, with low, grassy banks five feet high, covered with scattering swamp Maple-trees. "The Megalloway River is extremely serpentine and wild in its course, winding its way amid high mountains, while its banks are composed of sandy loam, covered thickly with Maple-trees." [Illustration: FRYE'S FALLS, ON A TRIBUTARY OF ELLIS RIVER.] "The Umbagog Lake is an irregular, shallow sheet of water, with grassy and boggy shores, and is surrounded by lofty mountains of granite, which in September are clothed with the red and yellow foliage of Maple and Birch trees, the former greatly predominating, and covering the mountains to their very summits." Among other objects of romantic interest are "Frye's Falls, in Andover Surplus," upon Frye's Stream, so called. "This stream rushes over a precipitous mass of granite, gneiss, and mica slate rocks, precipitating itself by a fall of twenty-five feet into a rocky basin below. The chasm is fifteen feet wide, and the basin fifty-five feet broad. Here the waters form a beautiful pool, and then leap again, by a second fall of twenty feet, into another larger and shallower reservoir, from which they descend gradually to Sawyer's Brook, running into Ellis River." [Illustration: RUMFORD BRIDGE, ANDROSCOGGIN RIVER.] There are about sixty saw-mills on this river and its tributaries, thirty-two of which are at Brunswick and Topsham; about two hundred shingle machines, most of which manufacture for home consumption; ten only, or thereabouts, manufacture for markets abroad, which cut about three hundred thousand to a machine. Average price per _M._, $2.75. Though there are said to be fifty clap-board machines of some sort on the river, yet only "nine can be reckoned as manufacturing for market," "which, owing to the scanty supply of timber, cut only about fifty _M._" to a machine. Average price of clap-boards per _M._, $22.50. There are only nine lath machines, which, as is reported, for want of material, cut only about two hundred and fifty thousand to a machine. Average price per _M._, $1.18. Throwing the whole, then, into a tabular form, we have presented for our inspection the results of the lumbering operations on the Androscoggin, for the market, as follows: ANDROSCOGGIN.
