 The mill achieved its largest extent in 1900, with 25,000 spindles, as part of the Arnold Print Works properties; business failures in 1878 and 1908 caused the mill to be part of the Arnold Print Works Reorganization Agreements.In 1929 Arnold sold the property to Sprague Electric, whose first major facility it was.Sprague moved some of its facilities from Quincy, Massachusetts to the Beaver Mill in 1930.
