Fort Jefferson was commenced long before the war, and is now a monument of the ineffectual military methods of thirty years ago. The work is a six-sided, two-tiered fort of majestic proportions, its faces pierced with over five hundred guns. How many millions of dollars have been expended in its erection it would be difficult to conjecture. The question why so important a work was built here is often asked, and we have heard the answer given that it was encouraged by the Key West slave-owners, through their representatives, to give employment to their slaves, who were engaged as laborers by the government. Garden Key, however, is the key of the gulf, and, as a prospective coaling-station in case of war, it was undoubtedly a spot to be held at all odds, and at the outbreak of the war it formed a convenient spot for the confinement of certain prisoners, as many as three thousand being kept there at one time. Now the great fort figures as a picture of desolation and is slowly falling to decay, deserted save by the memories of the great conflict, a lighthouse-keeper, and a guard. Once within the great enclosure, the reason for its having been called Garden Key becomes apparent. The neighboring islands are covered with prickly pear, mangroves, and bay-cedars, while here clumps of cocoanuts rear their graceful forms, their long rustling leaves, which convey to the distant listener the cooling impression of falling rain, reaching high over the top of the fort. On the west side grows a small grove of bananas, while against the cottage walls luxuriant vines climb in wild confusion. What was once the parade-ground is covered by a thick growth of wiry grass, in which gopher- and crab-holes lay traps for the unwary. In fact, far from being the forbidding spot it has been painted, Dry Tortugas seemed to us a veritable garden in the path of the great Gulf Stream. On the afternoon of our arrival the Bull Pup was got under way and headed through a circuitous channel to East Key, off which we came to anchor about dusk. Blankets and other articles indispensable for a night on the beach were carried ashore, and camp formed on the edge of the bay-cedars. East Key comprises about thirty acres of sand, thickly covered with a low growth of bay-cedar, in which the rude nests of the noddy are found, while here and there in the undergrowth are great patches of cactus or prickly pear, affording lurking-places for innumerable purple-backed crabs of ferocious mien. "Turklin'," said old Sandy, as we lay stretched on the sand, waiting for the moon, "is right in de line o' hard wu'k, an' I 'spec's yo' chillun is a-hankerin' after yo' mudder." The two children, both hard on thirty, indignantly denied that they had anything but an extreme fondness for labor.
