4.—Governor Roberts, General Lewis, and Doctor Day, dined with us in the ward-room. The Governor is certainly no ordinary person. In every situation, as judge, ruler, and private gentleman, he sustains himself creditably, and is always unexceptionable. His deportment is dignified, quiet, and sensible. He has been tried in war as well as in peace, has seen a good share of fighting, and has invariably been cool, brave, and successful. He is a native of Virginia, and came from thence in 1828. The friends of Colonization can hardly adduce a stronger argument in favor of their enterprise, than that it has redeemed such a man as Governor Roberts from servitude, and afforded him the opportunity (which was all he needed) of displaying his high natural gifts, and applying them to the benefit of his race.

To-night we had a Kroo-dance on the forecastle. It was an uncouth and peculiar spectacle, characterized by singing, stamping, and clapping of hands, with a great display of agility. National dances might be taken as no bad standard of the comparative civilisation of different countries. A gracefully quiet dance is the latest flower of high refinement.

5.—Two vessels descried standing in; and bets were five to one that they were the Macedonian and Decatur. It proved otherwise; they were a British gun-brig and French merchant-schooner.

8.—It has been raining for three days, almost incessantly. No Macedonian yet.

10.—Dined on shore. Our captain and five officers, the master and surgeon of an English merchantman, and the captain of the French schooner, were of the party. It was a pleasant dinner. The conversation turned principally upon the trade and customs of the coast. The slave-trade was freely discussed; and the subject had a peculiar interest, under the circumstances, because this identical Frenchman, at table with us, is suspected to have some connection with it. It is merely a surmise. The French captain speaks a little English; but, after dinner, as a matter of courtesy, we all adopted his native language. Our friend Colonel Hicks, as usual, did most of the talking; he is as shrewd, agreeable, and instructive a companion, as may often be met with in any society.

The dinner-conversation, above alluded to, suggests some remarks in reference to the slave-trade. There is great discrepancy in the various estimates as to the number of slaves annually exported from Africa. Some authorities rate it as high as half a million. Captain Bosanquet, R.N., estimates that fifteen thousand are annually sent to the West Indies, and a greater number to Arabia, all of which are from Portuguese settlements. He affirms that the trade has increased very much between the years 1832 and 1839, and particularly in the latter part of that period; an effect naturally consequent upon the great number of captures made by the English cruisers. A trader, for instance, contracting to introduce a given number of slaves into Cuba, must purchase more on the coast to make up for those lost by capture. Captain Brodhead, another British officer, says that the number of slaves carried off is grossly exaggerated, and that the English papers told of thousands being shipped from a port, where he lay at anchor during the period indicated, and for fifty days before and afterwards; in all which time, not a slave vessel came in sight. Doctor Madden states, that, during his residence in Cuba, the number of slaves annually imported was twenty-five thousand. Sir Thomas Fowell Buxton calls it one hundred and fifteen thousand! Her Majesty's Commissioners say that the number is as well known as any other statistical point, and that it does not exceed fifteen thousand. The slave-trade rose to a great height in 1836, owing principally to the high price of colonial produce. I was in Cuba in that year, and witnessed the great activity that prevailed in buying negroes, and forming plantations, especially those of sugar. The prices have since fallen, and the slave-trade decreased, on the plain principle of political economy, that the demand regulates the supply.

The English cruisers are doubtless very active in the pursuit of vessels engaged in this traffic. The approbation of government and the public (to say nothing of £5 head-money for every slave recaptured, and the increased chance of promotion to vacancies caused by death) is a strong inducement to vigilance. But, however benevolent may be the motives that influence the action of Great Britain, in reference to the slave-trade, there is the grossest cruelty and injustice in carrying out her views. Attempts are now being made to transport the rescued slaves in great numbers to the British West India islands, at the expense of government. It is boldly recommended, by men of high standing in England, to carry them all thither at once. The effect of such a measure, gloss it over as you may, would be to increase the black labor of the British islands, by just so much as is deducted from the number of slaves, intended for the Spanish or Brazilian possessions. "The sure cure for the slave-trade" says Mr. Laird, "is in our own hands. It lies in producing cheaper commodities by free labor, in our own colonies." And, to accomplish this desirable end, England will seize upon the liberated Africans and land them in her West India islands, with the alternative of adding their toil to the amount of her colonial labor, or of perishing by starvation. How much better will their condition be, as apprentices in Trinidad or Jamaica, than as slaves in Cuba? Infinitely more wretched! English philanthropy cuts a very suspicious figure, when, not content with neglecting the welfare of those whom she undertakes to protect, she thus attempts to made them subservient to national aggrandizement. The fate of the rescued slaves is scarcely better than that of the crews of the captured slave-vessels. The latter are landed on the nearest point of the African coast, where death by starvation or fever almost certainly awaits them.

I am desirous to put the best construction possible on the conduct as well of nations as of individuals, and never to entertain that cold scepticism which explains away all generosity and philanthropy on motives of selfish policy. But it is difficult to give unlimited faith to the ardent and disinterested desire professed by England, to put a period to the slave-trade. If sincere, why does she not, as she readily might, induce Spain, Portugal, and Brazil, to declare the traffic piratical? And again, why is not her own strength so directed as to give the trade a death-blow at once? There are but two places between Sierra Leone and Accra, a distance of one thousand miles, whence slaves are exported. One is Gallinas; the other New Sesters. The English keep a cruiser off each of these rivers. Slavers run in, take their cargoes of human flesh and blood, and push off. If the cruiser can capture the vessels, the captors receive £5 per head for the slaves on board, and the government has more "emigrants" for its West India possessions. Now, were the cruisers to anchor at the mouths of these two rivers, the slavers would be prevented from putting to sea with their cargoes, and the trade at those places be inevitably stopped. But, in this case, where would be the head-money and the emigrants?

It has been asserted that the colonists of Liberia favor the slave-trade. This is not true. The only places where the traffic is carried on, north of the line, are in the neighborhood of the most powerful English settlements on the whole coast; while even British authority does not pretend that the vicinity of the American colonies is polluted by it. Individuals among the colonists, unprincipled men, may, in a very few instances, from love of gain, have given assistance to slavers, by supplying goods or provisions at high prices. But this must have been done secretly, or the law would have taken hold of them. Slavers, no doubt, have often watered at Monrovia, but never when their character was known. On the other hand, the slave stations at St. Paul's river, at Bassa, and at Junk, have undeniably been broken up by the presence of the colonists. Even if destitute of sympathy for fellow-men of their own race and hue, and regardless of their deep stake in the preservation of their character, the evident fact is, that self-interest would prompt the inhabitants of Liberia to oppose the slave-trade in their vicinity. Wherever the slaver comes, he purchases large quantities of rice at extravagant rates, thus curtailing the supply to the colonist, and enhancing the price. Moreover, the natives, always preferring the excitement of war to the labors of peace, neglect the culture of the earth, and have no camwood nor palm-oil to offer to the honest trader, who consequently finds neither buyers nor sellers among them.

The truth is, the slave-traders can dispense with assistance from the Liberian colonists. They procure goods, and everything necessary to their trade, at Sierra Leone, or from any English or American vessel on the coast. If the merchantmen find a good market for their cargoes, they are satisfied, whatever be the character of their customers. This is well understood and openly avowed here. The English have no right to taunt the Americans, nor to claim higher integrity on their own part. They lend precisely the same indirect aid to the traffic that the Americans do, and furnish everything except vessels, which likewise they would supply, if they could build them. It is the policy of the English ship-masters on the coast to represent the Americans as engaged in the slave-trade; for if, by such accusations, they can induce British or American men-of-war to detain and examine the fair trader, they thus rid themselves of troublesome rivals.
