The slaves diminished every year in the absence of additions from outside, as the whites would have done under similar circumstances. That there was no natural increase was mainly due to the fact that the sexes were unequal, and then, again, maternal affection was sadly wanting in the women, who seemed to care less for their children than some domestic animals. This state of things was mainly the outcome of the system, which was undoubtedly immoral, but the mental disabilities of the race must also be taken into consideration. The anti-slavery party considered that environment was everything; if they could only free the negro from compulsory servitude he would at once become an industrious labourer. Yes, in their opinion, if he had the incentive of wages, it would make him a credit to himself and his community. The slaves, they said, were worked to death, yet as free men they would do more and perform their tasks better. Their experience with free workmen led to these conclusions, but this could not apply to the West Indies nor to the negro race. The anti-slavery party was very strong, and although it is not stated that they took "Perish the colonies!" for their motto, it is very certain that they cared little about the future of either white or black as long as they carried their object. To this end every possible case of oppression and ill-treatment was exaggerated, and spoken of as if it were common, notwithstanding that the case only came to their notice through the trial and punishment of the offender. The fact was the planter could not afford to ill-treat his slave--no other animal of his live stock was of so much value. If a valuable horse were killed another could be obtained to replace him, but this was almost impossible in the case of the negro. Formerly, when he cost about £20, it might have paid to work him to death; now that his price was five or six times as much, self-interest alone prevented ill-treatment. There was a strong public opinion in every colony which prevented cruelty, and there were societies in some which gave prizes to those in charge of estates who raised the greatest number of children in proportion to their negroes. This breeding of negroes was necessarily very slow work, and did little to make up for the stoppage of importation. It followed, therefore, that every year the amount of available labour became less.
