There is something marvelous in the purity and whiteness of congealed spray. One might think it to be frozen sunlight. And when, by reason of an angle or a curve, it is thrown into shadow, one sees where the rainbow has been caught and frozen in. After a day of sunshine which has been sufficiently warm to fill the atmosphere with aqueous vapor, if a sharp, still, cold night succeed, and if on this there break a clear, calm morning, the scene presented is one of unique and enchanting beauty. [Illustration: WINTER FOLIAGE] The frozen spray on every boll, limb, and twig of tree and shrub, on every stiffened blade of grass, on every rigid stem and tendril of the vines, is covered over with a fine white powder, a frosty bloom, from which there springs a line of delicate frost-spines, forming a perfect fringe of ice-moss, than which nothing more fanciful nor more beautiful can be imagined. 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.
