Then, as the day advances, the increasing warmth of the sun's rays dissolves this fairy frost-work and spreads it like a delicate varnish over the solid spray, giving it a brilliant polish rivaling the luster of the rarest gems; the mid-morning breeze sets in motion this flashing, dazzling forest, which varies its color as the sunlight-angle varies; and finally, when the waxing warmth and growing breeze loosen the hold of the icy covering in the tree-tops, and it drops to the still solid surface in the shade beneath,—the tiny particles with a silver tinkle and the larger pieces with the sharp, rattling sound of the castanet,—the ear is charmed with a wild, dashing rataplan, while a scene of strange enchantment challenges the admiration of the spectator.
Even more beautiful and fairy-like, if possible, is the garment of frozen fog with which all external objects are adorned and etherealized when the spring advances and the temperature of the water is raised. As the sharp, still night wears on, the light mists begin to rise, and when the morning breaks, the river is buried in a deep, dense bank of fog. A gentle wave of air bears it landward; its progress is stayed by everything with which it comes in contact, and as soon as its motion is arrested it freezes sufficiently to adhere to whatever it touches. So it grows upon itself, and all things are soon covered half an inch in depth with a most delicate and fragile white fringe of frozen fog. The morning sun dispels the mist, and in an hour the gay frost-work vanishes.
The ice islands are sometimes extensive. In the year 1856 the whole of the rocky bar above Goat Island was covered with ice, piled together in a rough heap, the lower end of which rested on Goat Island and the three Moss Islands lying outside of it, all of which were visited by different persons passing over this new route.
The ice formed on the rocks below the American Fall, stretched upward, reached the edge of the precipice just north of the Little Horseshoe, continued up-stream above Chapin's Island, spread out laterally from that to Goat Island on the south, and over nearly half of the American rapids to the north. At the brow of the precipice it accumulated upward until it formed a ridge some forty feet high. About fifteen rods up-stream another ridge was formed of half the height of the first. Every rock projecting upward bore an immense ice-cap. Around and between these mounds and caps horses were driven to sleighs, albeit the course was not favorable for quick time. The boys drew their sleds to the top of the large mound, slid down it, up-stream, and nearly to the top of the smaller hill.
On the lower or down-stream side, they would have had a clear course to the water below, at the brink of the Falls, and might have made "time" compared with which Dexter's minimum would have seemed only a funeral march. But with all Young America's passion for speed, he declined to try this route. The writer walked over the south end of Luna Island, above the tops of the trees.
The ice-bridge of that year filled the whole chasm from the Railway Suspension Bridge up past the American Fall. When the ice broke up in the spring, such immense quantities were carried down that a strong northerly wind across Lake Ontario caused an ice-jam at Fort Niagara. The ice accumulated and set back until it reached the Whirlpool, and could be crossed at any point between the Whirlpool and the Fort. It was lifted up about sixty feet above the surface, and spread out over both shores, crushing and destroying everything with which it came in contact. Many persons from different parts of the country visited the extraordinary scene.
At Lewiston the writer, with many others, saw a most remarkable illustration of the terrific power of this hydrostatic press. Just below the village, on the American side, there stood, about two rods from high-water mark, a sound, thrifty, tough white-oak tree, perhaps a hundred years old, and two feet in diameter. The ice, moved by the water, struck it near the ground and pressed it outward and upward, until it was actually pulled up by the roots—or rather some of the roots were broken and others were pulled out—and landed twenty feet farther away from the chasm.
Those who watched the operation stated that, from the time the ice touched the tree until it was landed on the bank above, the motion of the ice could not be detected by the eye.
