The classical taste which gave the name of the city built where the dappled heifer of Ilus lay down, to this modern town, when it was little more than a hamlet, and which dignified the irregular hill that overlooks it with the title of Mount Ida (called Ida Hill by the inhabitants), named this rocky peak Mount Olympus. We saw nothing upon its *' awful summit " to remind us of the Thessalian dwelling-place of the gods ; and the apparition nearest to that of " Olympian Jove " (whom the artists portrayed in human form) that we saw in the fading twilight, was a ragged boy, with a cigar in his mouth, vainly endeavouring to climb the sapling.

The peak of Olympus was once much higher. It has been carried away from time to time to furnish materials for docks, and in strengthening the dam, twelve hundred feet in length, which the State built across the Hudson at this point to furnish a feeder to the Champlain Canal. The water at the dam has a fall of about twelve feet, and at the east end is a heavy lock, constructed of hewn stone, through which -sloops and other

vessels are taken into the river above, and towed by steam-tugs, as we bave observed, up to Lansingburgh and "Waterford. Just above the dam, and near "Waterford, there is a communication between the canal and the river, and many loaded boats from the former there enter the latter, pass through the lock, and are towed, some to Troy and Albany, and others to New York. The dam also furnishes water power to a number of mills on the Troy shore below it, into which grain is taken from vessels lying at the docks, by means of "elevators" worked by the water wheels.
