The aboriginal agriculturists discussed here lived in a somewhat secluded environment, the Connecticut River Valley from Bellows Falls to the Connecticut line. In this long-occupied territory, surrounded by high ridges of volcanic origin, heavily wooded, and watered by innumerable spring-fed streams, the cultural development of the inhabitants was apparently of a homogeneous nature. As late as 1636, when the English began to establish plantations throughout the valley, the natives were found united in a well-defined River Confederacy, with frequent intercourse maintained through river travel. While trade routes probably connected this section with many other parts of the country, cultural contacts had apparently persisted among the river tribes in spite of occasional raids of warlike groups from other regions.
