It is indicative of the priority of importance which Las Casas habitually gave to spiritual over temporal aids, that he first had recourse to the priors of the religious orders, asking them to have their communities pray unceasingly and with special earnestness, that his mind might be illumined by divine grace to perceive what course he must follow. He next drew up his plan, but perhaps in no act of his long career is there less evidence of the action of divine guidance, for, in framing his project, he committed an error which he himself sincerely and frankly deplored with touching humility, and which has served all his detractors ever since as ground on which to bring a grave charge against him.
In obedience to the King's command conveyed to Las Casas through the Chancellor, he drew up a plan in which he proposed that labourers should be induced to emigrate to the Indies, by granting that each person, whether man or child, should have his expenses paid as far as Seville, the place of embarkation, at the rate of half a real per day. While waiting in Seville to start, the India House (Casa de Contractacion) was to lodge and feed them, their passage to Hispaniola was to be given them and their food furnished for one year. Any of the emigrants who, at the expiration of the first year, found themselves incapacitated on account of the climate to support themselves, should be entitled to further assistance in the form of a royal loan. Lands were to be given them gratis and also the requisite farming implements for working them, in which their rights as owners should be permanent and hereditary. A more liberal scheme of assisted emigration could hardly be imagined. Other inducements were held out to attract emigrants under the new regulations and Las Casas acceded to the request of certain of the colonists in Santo Domingo to ask the King's consent to the importation of negro slaves to replace the Indians who should be freed.
This recommendation cost Las Casas dearly enough and later exposed his reputation to unjustifiable attacks, some of which even represented him as having _introduced_ negro slavery into America; others as having been betrayed by blind zeal in favour of the Indians into promoting the slave-trade at the expense of the Africans. No one more sincerely deplored his course in this matter than he himself when he realised the significance of what he had done, and the sincerity and humility of his compunction should have sufficed to disarm his detractors. The most formal accusation made by a reputable historian against Las Casas is found in Robertson's _History of America_, vol. iii., Year 1517, in which he charges the apostle of the Indians with having proposed to Cardinal Ximenez to purchase a sufficient number of negroes from the Portuguese settlements on the coast of Africa and to transport them to America in order that they might be employed as slaves in working in the mines and tilling the ground. Cardinal Ximenez however, when solicited to encourage the commerce, peremptorily rejected the proposition because he perceived the iniquity of reducing one race of men to slavery when he was consulting about the means of restoring liberty to another. But Las Casas, from the inconsistency natural to men who hurry with headlong impetuosity towards a favourite point, was incapable of making the distinction. While he contended earnestly for the liberty of the people born in one quarter of the globe, he laboured to enslave the inhabitants of another region and in the warmth of his zeal to save the Americans from the yoke, pronounced it to be lawful and expedient to impose one still heavier on the African.
