Putting the maximum annual production of henequen or sisal hemp in Yucatan at 1,200,000 bales, of 400 pounds to the bale, and assuming an average yield of three bales per acre, indicates that about 400,000 acres of land are actually producing hemp in that country; and allowing for a margin of twenty five per cent of such area, to cover and provide for depletion and propagation, it would seem that about 500,000 acres of land is the approximate area now actually planted with and growing henequen on that peninsula. These statements are made to justify the calling of attention to the fact that large areas of more or less flat, rocky lands exist in various localities throughout the island of Cuba, notably in the western extremity of the Province of Pinar del Rio, along the north coast from the city of Matanzas to the Bahia de Cardenas, on the Cayos and, at intervals, along the north coast from Caibarien to the Bay of Nipe, and especially along the Caribbean Coast, in the vicinity of the Cienaga de Zapata; all of which lands are possessed of the same physical characteristics, and are subject to the same climatic conditions that apply to the lands in Yucatan now planted with henequen and at the present time successfully producing sisal hemp. The aggregate of these several areas of henequen lands is conservatively estimated at not less than 1,000,000 acres: or double the area now planted with henequen in Yucatan. About 9,000 acres of these Cuban lands are now actually planted with and successfully growing henequen; and about 5,000 acres are now producing sisal hemp which in quantity and quality compares favorably with the product of the best henequen lands in Yucatan. The results obtained from these lands now actually planted and producing are conclusive as to the results that could be obtained if other and larger areas of such lands should be planted with henequen. Furthermore a large part of these Cuban henequen lands are so level and have such uniform, unbroken surfaces that, at an expense less than that involved in preparing the henequen lands of Yucatan, they could be put in condition to be kept clean mainly by motor-driven mowing machinery, instead of the enormously expensive man-power machete system employed upon the rougher lands of Yucatan. In addition to such advantages these rocky areas either comprise, or are margined by, large areas of rich land capable of producing many important items required for human sustenance; while in Yucatan everything needed to sustain human life has to be imported.
