1750 (Approx) – Archbrook culvert connects Meadowbrook to Powow River

“Caleb [Pillsbury] and family removed to Amesbury in 1727, and he became a leading citizen of that town. He and Orlando Bagley devised a plan to tunnel Pond Ridge in order that the waters of Lake Attitash might flow more directly into Powow river, and also drain a large meadow north of the lake so that its crop of hay might be more valuable and more easily harvested. It is said that the two men who dug this very successful Isthmian canal received as their pay a barrel of rum.”  – From Historic Homes and Places, Volume 2, by William Richard Cutter, 1908.
