The soil of these Bahama Islands, composed of such unpromising ingredients, shows in its prolific yield how much vegetation depends for its sustenance upon atmospheric air, especially in tropical climes. The landlord of the Victoria Hotel told us, as an evidence of the fertility of the soil, that radish seeds which were planted on the first day of the month would sufficiently mature and ripen by the twenty-first--that is in three weeks--for use upon the table; and also that potatoes, tomatoes, cucumbers, and melons were relatively expeditious in ripening here after planting. Our mind reverted to the jugglers of Madras and Bombay, who made an orange-tree grow from the seed, and bear fruit before our very eyes, at a single sitting. The luscious pineapple, zapota, mango, pomegranate, guava, star-apple, citron, custard-apple, mammee, and other fruits abound. The profuseness and variety of beautiful ferns and orchidaceous plants will also be sure to attract the attention of the Northern visitor. The rocky formation of the soil produces good natural roads, so that a long drive in the environs of Nassau is like a pleasure excursion over a well-macadamized thoroughfare. We were told of a delightful drive of fifteen miles in length which follows the sea beach the whole distance, but did not find time to test its attractions, though strongly tempted by the excellence of the roads. Here, as in other tropical regions, each month has its special floral display, although there are many, and indeed a majority, of the plants which continue to flower all the year round. We observed that the stone walls and hedges were now and again covered for short spaces with the coral-vine, whose red blossoms, so pleasing to the eye, emit no odor. The yellow jasmine was dazzlingly conspicuous everywhere, and very fragrant. Red and white roses, various species of cacti, and tube-roses bloomed before the rude thatched cabins of the negroes in the environs, as well as in the tiny front gardens of the whites in the streets of the town; while red, white, and pink oleanders grew as tall as trees, and flower here every month in the year. The night-blooming cereus abounds, opening just at sunset, and closing again at break of day. The outside leaves of this poetical flower are of a pale green, the inner ones of a pure wax-like white, and the petals light yellow. Complete, it is about eight inches long, and from twelve to fifteen in circumference.
