There are fourteen saws reported which manufacture for exportation. With a proper head of water and a sufficient number of logs, one saw is capable of cutting a million feet per annum. But, in the absence of the necessary supply of logs, we should feel inclined to limit the amount manufactured per saw to one hundred and fifty thousand feet, board measure, the average price of which is said to be $12 per _M._ Of lath machines there are six reported, capable, under favorable circumstances, of cutting one million pieces per annum to a machine. But in this instance, from the scanty supply of material, we should not feel warranted in an estimate exceeding two hundred thousand to each machine as the average product, worth probably about the same as similar kinds of lumber on the Androscoggin. Six shingle machines may be supposed to produce a limited amount of this kind of lumber, for the same general reason assigned for the scanty supply of other kinds. Two hundred and fifty thousand to each machine, worth two dollars and fifty cents per _M._, may therefore be considered not extravagant. Some attention has been given to factory operations on this river at Sacarappa, where there is one mill with three hundred and sixty looms, whether for cotton or wool I am uninformed. TABLE. Number of saws manufacturing for market, 14. Number of lath and shingle machines, do., 12. Amount of long lumber 2,100,000, at $12.00 = $25,200. Number of thousand shingles 1,500,000, at 2.50 = 3,750. Number of thousand laths 1,200,000, at 1.12 = 1,344. ------ Total $30,294. Though this is comparatively a small lumber operation, still, provided the truth has been approximated in the estimates made, this done annually amounts to no mean revenue, and affords employment to not a few persons, supplying bread for many mouths, and enriching those who conduct the business. While such operations build up many beautiful villages along the romantic banks of those fine streams and rivers where falls occur, they also give an impulse to the farming interests of the country contiguous, and serve as so many little hearts in the great system, whose pulsations vibrate with general intelligence, education, and improved manners throughout the interior. For the principal _facts_ involved in the view given of the Presumpscot and its lumbering interests, I am mainly indebted to the kindness of E. Clarke, M.D., of Portland, Maine.
