Next to the color of the ocean, in its power to suggest remoteness and unfamiliarity, is the character of the vegetation. The flora of Key West is wholly tropical, and in my first ramble through the city I did not discover a single plant, shrub, tree, or flower that I had ever seen in the North except the oleander. Even that had wholly changed its habits and appearance, and resembled the pot-grown plant of Northern households only as the gigantic sequoia of California resembles the stunted Lilliputian pine of the Siberian tundra. The Key West oleander is not a plant, nor a shrub; it is a tree. In the yard of a private house on Carolina Street I saw an oleander nearly thirty feet in height, whose branches shaded an area twenty feet or more in diameter, and whose mammoth clusters of rosy flowers might have been counted by the hundred. Such an oleander as this, even though its leaves and blossoms may be familiar, seems like a stranger and an exotic, and, instead of modifying the impression of remoteness and alienation made by the other features of the tropical environment, it deepens and intensifies it. Among the vines, plants, shrubs, and trees that I noticed and identified in the streets and private grounds of Key West were jasmine, bergamot, poinsettia, hibiscus, almond, banana, sapodilla, tamarind, Jamaica apple, mango, Spanish lime, cotton-tree, royal poinciana, "Geiger flower" (a local name), alligator-pear, tree-cactus, sand-box, cork-tree, banian-tree, sea-grape, cocoanut-palm, date-palm, Indian laurel, Australian pine, and wild fig. Most of these trees and shrubs do not grow even in southern Florida, and are to be found, within the limits of the United States, only in southern California and on the island of Key West.
A mere perusal of this long list of unfamiliar names will enable the reader to understand why the vegetation of the island reinforces the impression of strangeness and remoteness already made by the color of the sea.
Key West, after the outbreak of war, had two chief centers of interest and excitement: first, the harbor, between Fort Taylor and the government wharf, where lay all the monitors, cruisers, and gunboats of the North Atlantic Squadron that were not actually engaged in sea service; and, second, the Key West Hotel, which was the headquarters of the war correspondents, as well as of naval officers assigned to shore duty, and visitors on all sorts of business from the North. I found it hard to decide which of these two centers would offer better opportunities and facilities for observation and the acquirement of knowledge. If I stayed on board a vessel in the harbor, I should miss the life and activity of the city, the quick delivery of daily papers from the North, the news bulletins posted every few hours in the hotel, and all the stories of fight, peril, or adventure told on shady piazzas by officers and correspondents just back from the Cuban coast; while, on the other hand, if I established myself at the hotel, I could not see the bringing in of Spanish prizes from the Florida Strait, the arrival and departure of despatch-boats with news and orders, the play of the search-lights, the gun practice of the big war-ships, the signaling, the saluting, and the movements generally of the fleet.
