_Tobacco._ This plant (_nicotiana tabacum_) is indigenous to America, but the most valuable is that raised in Cuba. Its cultivation is costly, for it requires a new soil of uncommon fertility, and a great amount of heat. It is very exhausting to the land. It does not, it is true, require much labor, nor costly machinery and implements. It is valued according to the part of the island in which it grows. That of greatest value and repute, used in the manufacture of the high cost cigars, is grown in the most westerly part of the island, known popularly as the _Vuelta de Abajo_. But the whole western portion of the island is not capable of producing tobacco of the best quality. The region of superior tobacco is comprised within a parallelogram of twenty-nine degrees by seven. Beyond this, up to the meridian of Havana, the tobacco is of fine color, but inferior aroma (the Countess Merlin calls this aroma the vilest of smells); and the former circumstance secures it the preference of foreigners. From Consolacion to San Christoval, the tobacco is very hot, in the language of the growers, but harsh and strong, and from San Christoval to Guanajay, with the exception of the district of Las Virtudes, the tobacco is inferior, and continues so up to Holguin y Cuba, where we find a better quality. The fertile valley of Los Guines produces poor smoking tobacco, but an article excellent for the manufacture of snuff. On the banks of the Rio San Sebastian are also some lands which yield the best tobacco in the whole island. From this it may be inferred how great an influence the soil produces on the good quality of Cuban tobacco; and this circumstance operates more strongly and directly than the slight differences of climate and position produced by immediate localities. Perhaps a chemical analysis of the soils of the Vuelta de Abajo would enable the intelligent cultivator to supply to other lands in the island the ingredients wanting to produce equally good tobacco. The cultivators in the Vuelta de Abajo are extremely skilful, though not scientific. The culture of tobacco yields about seven per cent. on the capital invested, and is not considered to be so profitable on the island as of yore. Cacao, rice, plantains, indigo, cotton, sago, yuca (a farinaceous plant, eaten like potatoes), Indian corn, and many other vegetable productions, might be cultivated to a much greater extent and with larger profit than they yield. We are astonished to find that with the inexhaustible fertility of the soil, with an endless summer, that gives the laborer two and three crops of some articles a year, agriculture generally yields a lower per centage than in our stern northern latitudes. The yield of a _caballeria_ (thirty-two and seven-tenths acres) is as follows:
