Humboldt and others have alluded to a striking prediction made by Girolamo Benzoni, an Italian traveller who visited the islands and Terra Firma early in the sixteenth century, and witnessed the condition and temper of the blacks. It is of the clearest kind. He says,[10] after speaking of marooning in Hayti,--_"Vi sono molti Spagnuoli che tengono per cosa certa che quest' Isola in breve tempo sara posseduta da questi Mori. Et per tanto gli governatori tengono grandissima vigilanza"_ etc.: "There are many Spaniards who hold it for certain that in a brief time this island will fall into the hands of the Africans. On this account the governors use the greatest vigilance." He goes on to remark the fewness of the Spaniards, and afterwards gives his own opinion to confirm the Spanish anticipation. Nothing postponed the fulfilment of this natural expectation till the close of the eighteenth century, but the sudden decay into which the island fell under Spanish rule, when it became no longer an object to import the blacks. Many Spaniards left the island before 1550, from an apprehension that the negroes would destroy the colony. Some authorities even place the number of Spaniards remaining at that time as low as eleven hundred. The common opinion that Las Casas asked permission for the colonists to draw negroes from Africa, in order to assuage the sufferings of the Indians, does not appear to be well-founded. For negroes were drawn from Guinea as early as 1511, and his proposition was made in 1517. The Spaniards were already introducing these substitutes for the native labor, regardless of the ordinance which restricted the possession of negroes in Hayti to those born in Spain. It is not improbable that Las Casas desired to regulate a traffic which had already commenced, by inducing the Government to countenance it. His object was undoubtedly to make it easier for the colonists to procure the blacks; but it must have occurred to him that his plan would diminish, as far as possible, the miseries of an irregular transfer of the unfortunate men from Africa. (See Bridge's _Jamaica, Appendix, Historical Notes on Slavery._ The Spaniards had even less scruple about their treatment of the negroes than of the Indians, alleging in justification that their own countrymen sold them to the traders on the Guinea coast!)
