Teneriffe, from its great elevation, and gradual slope to the sea, possesses every variety of vegetation from the tropic to the frozen regions. In the first or lower region are found the date, palm, pine-apple, alligator-pear, and sugar cane, tea and coffee trees, lemons, citrons, oranges and grapes; the next region is that of grain and fruits, and trees of temperate climates; next follow the chesnuts, pines (Pinus Cananensis), and other hardy Alpine trees; then the region of heaths, laurels, and other evergreens; and at the extreme limit of vegetation, a considerable distance from the summit, the white broom (Spartium Nubigenum.) The population of the Canary Islands is about 200,000, viz. Teneriffe, 80,000; Grand Canary, 60,000; Palma, 25,000; Lanzerota, 15,000; Forteventura, 10,000; Heirro, 4,000; Gomera, 6,000.
The exports, exclusive of the coasting trade, are wines, barilla, orchilla weed, rock-moss, safflower, (hay-saffron,) and silks. The imports are sugar, cocoa, oil, tobacco, paper, &c. from Cadiz; earthenware, from St. Lucia; brandy, from Catalonia; dry goods, cloth, iron, and hardware, from England; and staves, soap, candles, and rice from the United States of America.
The volcanic nature of the soil of the Canary Islands renders it extremely favourable to the cultivation of the vine, which grows luxuriantly in Teneriffe, where more than three-fourths of all the wines exported from the Canaries is produced. The Teneriffe wines are of the same description and varieties as the wines of Madeira, namely, Tinto, Verdelho, Gual, Listan, Malvasia,[5] &c., but they are not equal in quality to the fine wines of the south side, yet superior to the wines of the north side, of that island. They are distinguished by what may be called the generic denominations of dry and sweet. The dry is well known by the name of Vidonia, and the sweet as Malvasia. The first quality of the former can only be obtained from the most respectable merchants, it being a very common process to convert it, by admixtures, into a counterfeit of Madeira, or sherry, and occasionally to drug it with port. The strongest quality of the celebrated wine called sack,[6] is made in Teneriffe, Grand Canary, and Palma.
