Mr. Mackenzie, in his “Notes on Hayti,” vol. ii., discusses the question of population, but the tables he inserts in his work vary so greatly that no reliance can be placed on them. In one, the population in 1824 of the French portion of the island is stated to be 351,716; in another, given in full detail as to each district, it is put at 873,867, whilst he adds that Placide Justin had previously estimated the population at 700,000, and General Borgella, a good authority, stated it at a million. It is evident that no one had very precise data on which to found an estimate. During the struggle between the French and the coloured races, the whole of the whites were either driven out of the country or killed, and some slaves were exported to Cuba and the United States. What remained, therefore, of the two other sections constituted the population of the empire of Dessalines. During the Presidency of General Geffrard (1863), I heard him remark, that from the best official information he could get, the population had increased to over 900,000. This estimate must be largely founded on conjecture. The negro race is undoubtedly prolific, and in a hundred years ought to have more than doubled--nay, in so fertile a country, with unlimited supplies of food, more than quadrupled its population. The losses during the war of independence were considerable, as there was no mercy shown by either side, and the sanguinary strife lasted many years. The long civil war between Pétion and Christophe was kept up during the whole reign of the latter, but probably did not cost the country so many lives as the building of the great mountain-fortress of La Ferrière and the handsome palace of Sans Souci. During the Presidency of Boyer, lasting twenty-five years, there was peace, and ample time was given, for the population to make up for all previous losses; but after his departure came the wars with Santo Domingo and civil strife. All these causes, however, would only have slightly checked population. If you ask a Haytian how it is that his country remains comparatively so thinly peopled, he will answer that the negresses take but little care of their children, and that at least two-thirds die in infancy. After reading the chapter on Vaudoux worship and cannibalism, I fear some of my readers may come to another conclusion. I cannot, however, think that these fearful excesses can be carried to the extent of greatly checking the increase of population. That the negresses are careless mothers is highly possible, and in the interior there are few, if any, medical men to whom they can apply in case of need.
