At length the session of 1807 commenced. It was judged advisable by Lord Grenville, that the expected motion on this subject should, contrary to the practice hitherto adopted, be agitated first in the Lords. Accordingly, on the 2nd of January he presented a bill, called an act for the abolition of the Slave Trade; but he then proposed only to print it, and to let it lie on the table, that it might be maturely considered, before it should be discussed.
On the 4th, no less than four counsel were heard against the bill.
On the 5th the debate commenced. But of this I shall give no detailed account; nor, indeed, of any of those which followed it. The truth is, that the subject has been exhausted. They, who spoke in favour of the abolition, said very little that was new concerning it. They, who spoke against it, brought forward, as usual, nothing but negative assertions and fanciful conjectures. To give therefore what was said by both parties at these times, would be but useless repetition[A]. To give, on the other hand, that which was said on one side only would appear partial. Hence I shall offer to the reader little more than a narrative of facts upon these occasions.
[A]: The different debates in both Houses on this occasion would occupy the half of another volume. This is another circumstance, which reconciles me to the omission. But that, which reconciles me the most is, that they will be soon published. In these debates justice has been done to every individual concerned in them.
Lord Grenville opened the debate by a very luminous speech. He was supported by the Duke of Gloucester, the Bishop of Durham (Dr. Barrington), the Earls Moira, Selkirk, and Roslyn, and the Lords Holland, King, and Hood. The opponents of the bill were the Duke of Clarence, the Earls of Westmoreland and St. Vincent, and the Lords Sidmouth, Eldon, and Hawkesbury.
The question being called for at four o'clock in the morning, it appeared that the personal votes and proxies in favour of Lord Grenville's motion amounted to one hundred, and those against it to thirty-six. Thus passed the first bill in England, which decreed, that the African Slave Trade should cease. And here I cannot omit paying to his Highness the Duke of Gloucester the tribute of respect, which is due to him, for having opposed the example of his royal relations on this subject in behalf of an helpless and oppressed people. The sentiments too, which he delivered on this occasion, ought not to be forgotten. "This trade," said he, "is contrary to the principles of the British constitution. It is, besides, a cruel and criminal traffic in the blood of my fellow-creatures. It is a foul stain on the national character. It is an offence to the Almighty. On every ground therefore on which a decision can be made; on the ground of policy, of liberty, of humanity, of justice, but, above all, on the ground of religion, I shall vote for its immediate extinction."
On the 10th of February, the bill was carried to the House of Commons. On the 20th counsel were heard against it; after which, by agreement, the second reading of it took place. On the 23rd the question being put for the commitment of it, Lord Viscount Howick (now Earl Grey) began an eloquent speech. After he had proceeded in it some way, he begged leave to enter his protest against certain principles of relative justice, which had been laid down. "The merchants and planters," said he, "have an undoubted right, in common with other subjects of the realm, to demand justice at our hands. But that, which they denominate justice, does not correspond with the legitimate character of that virtue: for they call upon us to violate the rights of others, and to transgress our own moral duties. That, which they distinguish as justice, involves in itself the greatest injury to others. It is not, in fact, justice, which they demand, but—favour—and favour to themselves at the expense of the most grievous oppression of their fellow-creatures."
He then argued the question on the ground of policy. He showed, by a number of official documents, how little this trade had contributed to the wealth of the nation, being but a fifty-fourth part of its export trade; and he contended that as four-sevenths of it had been cut off by His Majesty's proclamation, and the passing of the foreign slave bill in a former year, no detriment of any consequence would arise from the present measure.
He entered into an account of the loss of seamen, and of the causes of the mortality, in this trade.
He went largely into the subject of negro-population, in the islands from official documents, giving an account of it up to the latest date. He pointed out the former causes of its diminution, and stated how the remedies for these would follow.
