In 1798 when it was created, the Town of Lumberland was a rugged wilderness with 300,000 acres of continuous forests, interspersed with ponds, lakes and streams. The brooks and streams flowed into the Delaware River, which was the southwest border between New York and Pennsylvania.
A number of sawmills were built on the streams which flowed into the Delaware River. Streams with such names as Ten Mile River, Mongaup, Beaver Brook, and of course Halfway Brook. I have read that there were 8 or nine sawmills on Halfway Brook.
So which mill is The Mill on Halfway Brook talking about? Well, that will be a question that will be answered in the book, which I hope will be published in a couple months.
