Beginning in 1823, businessmen from Salem, Mass., developed a major textile manufacturing complex along the Lamprey River in Newmarket. No. 1 Mill was completed in 1824 in granite at a cost of $11,197.94, and Main Street was moved from the river's edge to its current location; after its cupola burned in 1858, the top two floors were removed and a bell tower was added to No. 2 Mill. Completed in 1825, No. 2 Mill used water power and more than 4,000 spindles to produce cotton textiles, turning out about 160,000 yards a week by 1869, with supplies brought by packet boats and schooners including the Helen Mar, the North America, and the Pembroke, which carried cotton from New Orleans to Boston for 62.5 cents per 100 pounds. No. 3 Mill, built in 1827 from granite quarried on Durham Point, received machinery in 1829 including 1,034 spindles. No. 4 Mill, built in 1869, used smaller trap rock left from the original quarries, and the agent's office stood at its north end. No. 5 Mill, built in 1881 as a two-story brick structure using local brick, began with looms weaving unbleached cotton shirting and sheeting, and these goods eventually were valued at more than $1 million per year. No. 6 Mill was added in 1892 as an extension to the south end of No. 5 and, like the other mills except No. 7 and No. 8, was water-powered. Built in 1901 in the No. 3 Mill yard, the three-story brick No. 7 Mill increased weaving capacity. No. 8 Mill, built in 1917 and known as The Great Weave Shed, covered five acres as once the largest single textile room in the world; dozens of houses were moved to neighboring streets to make way for it, and until its closure in 1934 it produced silk casket linings, fur capes, and men's hats. In 1934, after more than a century of operation and several years of labor unrest, the Newmarket Manufacturing Company abandoned 256 buildings instead of paying taxes, including all the mills, worker housing, and the 14-acre mill yard, ending the era of pounding looms and water-powered industrialization on the banks of the Lamprey.
