Until the latter part of the eighteenth century the number of female slaves in the sugar plantations of Cuba was extremely limited; and what may appear surprising is that a prejudice, founded on religious scruples, opposed the introduction of women, whose price at the Havannah was generally one-third less than that of men. The slaves were forced to celibacy on the pretext of avoiding moral disorder. The Jesuits and the Bethlemite monks alone renounced that fatal prejudice, and encouraged negresses in their plantations. If the census, no doubt imperfect, of 1775, yielded 15,562 female, and 29,366 male slaves, we must not forget that that enumeration comprehended the totality of the island, and that the sugar plantations occupy even now but a quarter of the slave population. After the year 1795, the Consulado of the Havannah began to be seriously occupied with the project of rendering the increase of the slave population more independent of the variations of the slave-trade. Don Francisco Arango, whose views were ever characterized by wisdom, proposed a tax on the plantations in which the number of slaves was not comprised of one-third females. He also proposed a tax of six piastres on every negro brought into the island, and from which the women (negras bozales) should be exempt. These measures were not adopted because the colonial assembly refused to employ coercive means; but a desire to promote marriages and to improve the condition of the children of slaves has existed since that period, when a cedula real (of the 22nd April, 1804) recommended those objects "to the conscience and humanity of the planters."
