The Works At Lawrence. The dam across the Merrimack, at the town of Lawrence, is to be, when completed, 900 feet in length, 36 wide at the bottom, 12 feet at the top, and varying in height from 25 to 40 feet, according to the bottom of the river. It is constructed of heavy stones laid in cement. It is intended that the dam shall be completed before winter sets in. The canal, from which water is to be used is a mile in length, following the bend of the river, at a distance from it of about 400 feet—one hundred feet wide at its mouth and sixty at the termination with a depth of 12 feet. The Atlantic Mills, already commenced, stretch down the river 1500 feet, where they strike the Bay State Mills, of 1000 feet in length The mills of these two corporations, when finished, will form a continuous line of smooth wall, of half a mile. The mills of the Atlantic Company will surpass in magnitude and solidity any other similar structures.-Salem Gazette
