“BIDDLE’S STAIRS.”

This structure takes its name from the Hon. Nicholas Biddle, the well-known president of the United States Bank, at whose expense the enterprise of building it was carried out in 1829. The bank at this place is 185 feet high. Part of this descent is accomplished by an open stairway, of ordinary inclination, and the remainder by the perpendicular shaft or tower, which is 80 feet high, the whole comprising 147 steps.

From the foot of the tower, a pathway to the right, under the shadow of the overhanging cliff, leads to the Center Fall, which constitutes the aqueous curtain of “Æolus’ Cavern.” A secure stairway leads to the entrance of the Cave, and the visitor passes under the Fall, into the stormy recess made in the solid rock. The Cavern derives its name from the peculiar atmospheric effects produced by the action of the falling water, the compression of the air establishing a perpetual tempest, like that in which Æolus, the god of the wind, is said to dwell.

The Cave is 100 feet high by 100 deep and 160 long, and its existence is due to the action of the waters upon the shale, leaving the more solid limestone rock overhanging.

UNDER THE CATARACT.

As one of the many novel experiences to be met in a visit to Niagara, the trip through this Cave will leave a lasting impression upon the memory. The sensations which wind and storm will always produce are here intensified by the novelty of the surroundings, and the realization of the fact that the forces of Nature are perpetually accomplishing here what they occasionally produce in the outer world. Add to this the spice of personal risk, really less than it seems to be, and the recollections of the occasion will be vivid and enduring.

From the foot of the stairway, another path leads to the river in front, and still another toward the Canadian or Horseshoe Fall. The latter is but little used, and is not kept in good condition. From a scaffolding 100 feet high, erected near the stairway in 1829, Sam Patch made his famous leap into the river, successfully accomplishing a feat, the repetition of which at Genessee Falls, shortly after, cost him his life.

Returning to the bank above, and continuing the walk along the brink, the next interesting point of observation is
