The contract was afterward given to another, but control was resumed by the Crown, in 1760. Finally, in 1817, cultivation and trade were declared to be free, subject only to taxation. [Illustration: STREET IN CAMAGUEY] In time, it became known that the choicest tobacco in the market came from the western end of Cuba, from the Province of Pinar del Rio. It was given a distinct name, _Vuelta Abajo_, a term variously translated but referring to the downward bend of the section of the island in which that grade is produced. Here is grown a tobacco that, thus far, has been impossible of production elsewhere. Many experiments have been tried, in Cuba and in other countries. Soils have been analyzed by chemists; seeds from the _Vuelta Abajo_ have been planted; and localities have been sought where climatic conditions corresponded. No success has been attained. Nor is the crop of that region produced on an extensive scale, that is, the choicer leaf. Not all of the tobacco is of the finest grade, although most of it is of high quality. There are what may be called "patches" of ground, known to the experts, on which the best is produced, for reasons not yet clearly determined. The fact is well known, but the causes are somewhat mysterious. Nor does the plant of this region appear to be susceptible of improvement through any modern, scientific systems of cultivation. The quality deteriorates rather than improves as a result of artificial fertilizers. The people of the region, cultivating this special product through generation after generation, seem to have developed a peculiar instinct for its treatment. It is not impossible that a time may come when scientific soil selection, seed selection, special cultivation, irrigation, and other systems, singly or in combination, will make possible the production of a standardized high-grade leaf in much greater quantity than heretofore, but it seems little probable that anything so produced will excel or even equal the best produced by these expert _vegueros_ by their indefinable but thorough knowledge of the minutest peculiarities of this peculiar plant. Thus far, it has not even been possible to produce it elsewhere in the island. It has been tried outside of the fairly defined area of its production, tried by men who knew it thoroughly within that area, tried from the same seed, from soils that seem quite the same. But all failed. Science may some day definitely locate the reasons, just as it may find the reason for deterioration in the quality of Cuban tobacco eastward from that area. The tobacco of Havana Province is excellent, but inferior to that of Pinar del Rio. The growth of Santa Clara Province is of good quality, but inferior to that of Havana Province, while the tobacco of eastern Cuba is little short of an offence to a discriminating taste.
