In the 1840s, Nathaniel Miller had a thread mill at River End, with young relatives working in it. It was powered by the water from a dam at Toil's End Brook built by John Boyd Jr. Later Dr. Miller and Caleb Sayles operated the mill under the firm name of Sayles and Miller. There is even mention of a lawsuit, against the Wollomonopoag Manufacturing Company, by Sayles and Miller, to recover a small sum of money.
