The Ratans, a most singular genus of creeping plants, luxuriate in the forests of tropical Asia. Sometimes their slender stems, armed with dreadful spines at every joint, climb to the summit of the highest tree; sometimes they trail along the ground; and while it is impossible to find out their roots among the intricate tangles of the matted underwood, their palm-like tops expand in the sunshine, the emblems of successful parasitism. They frequently render the forest so impervious, that the distinguished naturalist Junghuhn, while exploring the woods of Java, was obliged to be accompanied by a vanguard of eight men, one-half of whom were busy cutting the ratans with their hatchets, while the others removed the stems. These rope-like plants frequently grow to the incredible length of four or even six hundred feet, often consisting of a couple of hundred joints two or three feet long, and bearing at every knot a feathery leaf, armed with thorns on its lower surface. Though often extremely disagreeable to the traveller, yet they are far from being useless. The natives of Java and the other islands of the Eastern Archipelago cut the cane into fine slips, which they plait into beautiful mats, manufacture into strong and neat baskets, or twist into cordage of such strength and durability that it is even used with success in the formation of bridges across the watercourses and ravines. On turning from the Indian Ocean to Arabia and Africa, we enter upon a new world of palms, several of which are no less valuable than the cocoa-nut or the palmyra. The date-tree (_Phœnix dactylifera_), sung from time immemorial by the poets of the East, is as indispensable as the camel to the inhabitants of the wastes of North Africa and Arabia, and, next to the ‘ship of the desert,’ the devout Mussulman esteems it the chief gift of Allah. Few palms have a wider range, for it extends from the Persian Gulf to the borders of the Atlantic, and flourishes from the twelfth to the thirty-seventh degree of northern latitude. Groves of dates adorn the coasts of Valencia in Spain; near Genoa its plantations afford leaves for the celebration of Palm Sunday; and in the gardens of southern France a date-tree is sometimes seen growing among the oranges and olives. But it never bears fruit on these northern limits of its empire, and thrives best in the oases on the borders of the sandy desert. [Illustration: DATE TREE.] The date-palm is propagated by shoots, and the female tree bears its first fruits after four or five years. It is said to attain to an age of two centuries, but is rarely left standing longer than eighty years, when the trunk is tapped in spring, producing a kind of toddy, which is consumed in great quantities in ‘Biledulgerid,’ or the long line of oases situated to the south of the Atlas, and pre-eminently called the ‘land of dates.’
