Excellent tobacco is grown also in the Valley of Vinales, and may be successfully cultivated in nearly all of the valleys, pockets and basins that lie in the mountains of Western and Northern Pinar del Rio. This tobacco as a rule is graded in quality and price a little below that of the choice Vuelta Abajo center. Along the line of the Western Railroad, extending east from Consolacion del Sur to Artemisa, tobacco is also grown on the rolling lands and among the foothills that lie between the railroad and the southern edge of the Organ Mountains. This section, some fifty miles in length, with an average width of five or six miles, in which tobacco forms quite an important product, is known as the Semi-Vuelta or Partido district. Its leaf, however, brings in the open market only about half the sum received for the Vuelta Abajo. Nevertheless, at all points in this section where irrigation is possible, the culture of tobacco, especially when grown under cheese cloth, is profitable. Again, along the banks of several rivers south and east of the City of Pinar del Rio, especially along the Rio Hondo, a very good quality of tobacco is grown in the sandy lands rendered fertile by frequent overflow of these streams in the rainy season as they pass through the level lands of the southern plains. The chief enemies of the tobacco plant are some five or six varieties of worms that cut and eat the leaves. The larvae are hatched from the eggs of different kinds of moths that hover over the tobacco fields at night. Some are hatched from egg deposits on the plant itself, and at once begin eating the leaf, while others enter the ground during the day, coming out during the evening to feed, and no field unless protected by cheese cloth, or carefully watched by the patient veguero, can escape serious damage or complete destruction from these enemies of tobacco. It is a common thing at sundown to see the father, mother and all members of the family big enough to walk, down on hands and knees, hunting and killing tobacco worms. On bright moonlight nights, the worm hunt is carried on assiduously, and in the early hours of dawn the veguero and his family, if the crop is to be a success, must be up like the early bird and after the worm, otherwise there will be nothing to sell at the end of the season.
