Spring Mill until recently was the most populous village in the township, but owing to the demolition of its furnaces and several manufacturing establishments, its prosperity has been impaired.

The census of 1880 gives seven hundred and eighty-eight inhabitants; if this is no typographical error, it is entirely too high; the number of houses will not admit of half this population.

In this distance it has sufficient power to propel the whole year round the grist-mill mentioned, which was built here before 1715, and then owned by David Williams, next by Robert Jones.

The river is quite narrow where it flows through the hill and rises on both sides to an elevation of upwards of two hundred and fifty feet, contributing to the beauty of the scenery.

Its flourishing neighbor, Conshohocken, bids fair to absorb the entire place, it being no easy matter now to a stranger to tell where the one begins and the other ends.
