The two features of Key West scenery that appear, at first glance, to be most salient, and that contribute most to the impression of strangeness and remoteness made by the island as a whole, are, unquestionably, the color of the water and the character of the vegetation. The ocean in which the little coral key is set has a vividness and a delicacy of color that I have never seen equaled elsewhere, and that is not even so much as suggested by the turbid, semi-opaque water of the Atlantic off the coast of Massachusetts or New Jersey. It is a clear, brilliant, translucent green, pale rather than deep in tone, and ranging through all possible gradations, from the color of a rain-wet lawn to the pure, delicate, ethereal green of an auroral streamer. Sometimes, in heavy cloud-shadow, it is almost as dark as the green of a Siberian alexandrite; but just beyond the shadow, in the full sunshine, it brightens to the color of a greenish turquoise. In the shallow bay known as "the bight," the yellowish brown of the marine vegetation on the bottom blends with the pale green of the overlying water so as to reproduce on a large scale the tints of a Ural Mountain chrysolite, while two miles away, over a bank of sand or a white coral reef, the water has the almost opaque but vivid color of a pea-green satin ribbon. Even in the gloom and obscurity of midnight, the narrow slit cut through the darkness by the sharp blade of the Fort Taylor search-light reveals a long line of green, foam-flecked water. Owing to the very limited extent of the island, the ocean may be seen at the end of every street and from almost every point of view, and its constantly changing but always unfamiliar color says to you at every hour of the day: "You are no longer looking out upon the dull, muddy green water of the Atlantic coast; you are on a tropical, palm-fringed coral reef in the remote solitude of the great South Sea."
