They seem the evidence of the displeasure of Him who created man after His own image, at the unnatural attempt to govern the bones and sinews, the bodies and souls, of one portion of His children by the caprice, the avarice, the lusts of another; at that utter violation of the design of His merciful Providence, whereby the entire dependence of millions of His rational creatures is made to centre upon the will, the existence, the ability, of their fellow-mortals, instead of resting under the shadow of His own Infinite Power and exceeding love. I shall offer a few more facts and observations on this point. 1. A distinguished scientific gentleman, Mr. Coulomb, the superintendent of several military works in the French West Indies, gives it as his opinion, that the slaves do not perform more than one third of the labor which they would do, provided they were urged by their own interests and inclinations instead of brute force. 2. A plantation in Barbadoes in 1780 was cultivated by two hundred and eighty-eight slaves ninety men, eighty-two women, fifty-six boys, and sixty girls. In three years and three months there were on this plantation fifty-seven deaths, and only fifteen births. A change was then made in the government of the slaves. The use of the whip was denied; all severe and arbitrary punishments were abolished; the laborers received wages, and their offences were all tried by a sort of negro court established among themselves: in short, they were practically free. Under this system, in four years and three months there were forty-four births, and but forty-one deaths; and the annual net produce of the plantation was more than three times what it had been before.--[English Quarterly Magazine and Review, April, 1832.] 3. The following evidence was adduced by Pitt in the British Parliament, April, 1792. The assembly of Grenada had themselves stated, "that though the negroes were allowed only the afternoon of one day in a week, they would do as much work in that afternoon, when employed for their own benefit, as in the whole day when employed in their master's service." "Now after this confession," said Mr. Pitt, "the house might burn all its calculations relative to the negro population. A negro, if he worked for himself, could no doubt do double work. By an improvement, then, in the mode of labor, the work in the islands could be doubled." 4. "In coffee districts it is usual for the master to hire his people after they have done the regular task for the day, at a rate varying from 10d. to 15.8d. for every extra bushel which they pluck from the trees; and many, almost all, are found eager to earn their wages."
