A broad weir is thrown across the Schuylkill, which produces the sound and look of a cascade.

On the farther side of the river is a gentleman's seat, the beautiful lawns of which slope to the water's edge, and groups of weeping-willows and other trees throw their shadows on the stream.

The works themselves are enclosed in a simple but very handsome building of freestone, which has an extended front opening upon a terrace, which overhangs the river: behind the building, and divided from it only by a lawn, rises a lofty wall of solid limestone rock, which has, at one or two points, been cut into, for the passage of the water into the noble reservoir above.

From the crevices of this rock the catalpa was every where pushing forth, covered with its beautiful blossom.

Beneath one of these trees an artificial opening in the rock gives passage to a stream of water, clear and bright as crystal, which is received in a stone basin of simple workmanship, having a cup for the service of the thirsty traveller.
