He might reasonably, however, hope that they would not reckon any small or temporary disadvantage, which might arise from the abolition, to be a sufficient reason against it. It was surely not any slight degree of expediency, nor any small balance of profit, nor any light shades of probability on the one side, rather than on the other, which would determine them on this question. He asked pardon even for the supposition. The Slave-trade was an evil of such magnitude, that there must be a common wish in the committee at once to put an end to it, if there were no great and serious obstacles. It was a trade, by which multitudes of unoffending nations were deprived of the blessings of civilization, and had their peace and happiness invaded. It ought therefore to be no common expediency, it ought to be nothing less than the utter ruin of our islands, which it became those to plead, who took upon them to defend the continuance of it.

He could not help thinking that the West India gentlemen had manifested an over great degree of sensibility as to the point in question; and that their alarms had been unreasonably excited upon it. He had examined the subject carefully for himself; and he would now detail those reasons, which had induced him firmly to believe, not only that no permanent mischief would follow from the abolition; but not even any such temporary inconvenience, as could be stated to be a reason for preventing the House from agreeing to the motion before them; on the contrary, that the abolition itself would lay the foundation for the more solid improvement of all the various interests of those colonies.

In doing this he should apply his observations chiefly to Jamaica, which contained more than half the slaves in the British West Indies; and if he should succeed in proving that no material detriment could arise to the population there, this would afford so strong a presumption with respect to the other islands, that the House could no longer hesitate, whether they should, or should not, put a stop to this most horrid trade.

In the twenty years ending in 1788, the annual loss of slaves in Jamaica (that is, the excess of deaths above the births,) appeared to be one in the hundred. In a preceding period the loss was greater; and, in a period before that, greater still; there having been a continual gradation in the decrease through the whole time. It might fairly be concluded, therefore, that (the average loss of the last period being one per cent.) the loss in the former part of it would be somewhat more, and in the latter part somewhat less, than one per cent.; insomuch that it might be fairly questioned, whether, by this time, the births and deaths in Jamaica might not be stated as nearly equal. It was to be added, that a peculiar calamity, which swept away fifteen thousand slaves, had occasioned a part of the mortality in the last-mentioned period. The probable loss, therefore, now to be expected was very inconsiderable indeed.

There was, however, one circumstance to be added, which the West India gentlemen, in stating this matter, had entirely overlooked; and which was so material, as clearly to reduce the probable diminution in the population of Jamaica down to nothing. In all the calculations he had referred to of the comparative number of births and deaths, all the Negros in the island were included. The newly imported, who died in the seasoning, made a part. But these swelled, most materially, the number of the deaths. Now as these extraordinary deaths would cease, as soon as the importations ceased, a deduction of them ought to be made from his present calculation.

But the number of those, who thus died in the seasoning, would make up of itself nearly the whole of that one per cent., which had been stated. He particularly pressed an attention to this circumstance; for the complaint of being likely to want hands in Jamaica, arose from the mistake of including the present unnatural deaths, caused by the seasoning, among the natural and perpetual causes of mortality. These deaths, being erroneously taken into the calculations, gave the planters an idea, that the numbers could not be kept up. These deaths, which were caused merely by the Slave-trade, furnished the very ground, therefore, on which the continuance of that trade had been thought necessary.

The evidence as to this point was clear; for it would be found in that dreadful catalogue of deaths, arising from the seasoning and the passage, which the House had been condemned to look into, that one half died. An annual mortality of two thousand slaves in Jamaica might be therefore charged to the importation; which, compared with the whole number on the island, hardly fell short of the whole one per cent. decrease.

Joining this with all the other considerations, he would then ask, Could the decrease of the slaves in Jamaica be such—could the colonies be so destitute of means—could the planters, when by their own accounts they were establishing daily new regulations for the benefit of the slaves—could they, under all these circumstances, be permitted to plead that total impossibility of keeping up their number, which they had rested on, as being indeed the only possible pretext for allowing fresh importations from Africa? He appealed therefore to the sober judgment of all, whether the situation of Jamaica was such, as to justify a hesitation in agreeing to the present motion.

It might be observed also, that, when the importations should stop, that disproportion between the sexes, which was one of the obstacles to population, would gradually diminish; and a natural order of things be established. Through the want of this natural order a thousand grievances were created, which it was impossible to define; and which it was in vain to think that, under such circumstances, we could cure. But the abolition of itself would work this desirable effect. The West Indians would then feel a near and urgent interest to enter into a thousand little details, which it was impossible for him to describe, but which would have the greatest influence on population. A foundation would thus be laid for the general welfare of the islands; a new system would rise up, the reverse of the old; and eventually both their general wealth and happiness would increase.

He had now proved far more than he was bound to do; for, if he could only show that the abolition would not be ruinous, it would be enough. He could give up, therefore, three arguments out of four, through the whole of what he had said, and yet have enough left for his position. As to the Creoles, they would undoubtedly increase. They differed in this entirely from the imported slaves, who were both a burthen and a curse to themselves and others. The measure now proposed would operate like a charm; and, besides stopping all the miseries in Africa and the passage, would produce even more benefit in the West Indies than legal regulations could effect.
