The island is said to be capable of easily supporting three times its present population, the soil is so universally fertile and its resources are so well diversified. Though droughts occur in certain parts of the island, it is all extremely well watered, by more than one thousand streams, enumerated on the maps, and the dry sections have a system of irrigation which may be operated very effectually and with little expense. Of the 1,300 streams, forty-seven are considerable rivers.
TIMBER IN ABUNDANCE AND VARIETY.
Forests still cover all the elevated parts of the hill country of the interior, the inhabitants living mostly along the coast. The main need to set the interior teeming with a thrifty and healthy population is a system of good roads. The interior, with the exception of a few extensive savannas, is one vast expanse of rounded hills, covered with such rich soil that they may be cultivated to their summits. At present these forests are accessible only by mule tracks. "The timber of the island," says our official report, "comprises more than five hundred varieties of trees, and in the more elevated regions the vegetation of the temperate zones is not unknown. On the hills is found a luxuriant and diversified vegetation, tree-ferns and mountain palms being abundant. At a lower level grow many varieties of trees noted for their useful woods, such as the mahogany, cedar, walnut, and laurel. The mammee, guaiacum, and copal, besides other trees and shrubs valuable for their gum, flourish in all parts of the island. The coffee tree and sugar cane, both of which grow well at an altitude of a thousand feet or more, were introduced into the island—the former from Martinique in 1722, the latter from the Canaries, through Santo Domingo. Tobacco grows easily in the lowlands, while maize, pineapples, bananas, etc., are all prolific. The banana and plantain bear fruit within ten months after planting, and like the cocoa palm, live through an ordinary life-time."
MINERALS AND MINING.
"The mineral resources of the island," says our consul in his report, "have been very little developed, the only mineral industry of any importance being the salt works situated at Guanica, Salinas, and Cabo Rojo. Sulphides of copper and magnetic oxides of iron are found in large quantities, and formerly gold to a considerable extent was found in many of the streams. At present the natives still wash out nuggets by the crude process in use in the time of Ponce de Leon. Marble, carbonates, lignite, and amber are also present in varying quantities, and hot springs and mineral waters occur, the best known ones being at Coamo, near Santa Isabel."
COMMERCE.
NATIVE BELLES, PORTO RICO.
The commerce of Porto Rico amounted, in 1896, to $36,624,120, exceeding the records of all previous years; the increase, no doubt, being largely due to the unsettled condition of Cuba. The value of the exports for the same year was, for the first time for more than a decade, slightly in excess of that of the imports; the former being valued at $18,341,430, the latter at $18,282,690. The chief exports from the island are agricultural products. The principal articles are sugar, coffee, molasses, and tobacco; while rice, wheat, flour, and manufactured articles are among the chief imports. The value of the sugar and molasses exported to the United States during the ten years from 1888 to 1897 made up 95 per cent. of the total value of the exports to that country. Fruits, nuts, and spices are also exported to a small extent. Of the non-agricultural exports the most important are perfumery and cosmetics; chemicals, drugs, and dyes; unmanufactured wood, and salt.
