the real nature of American slavery. The commercial newspapers, published by slaveholders, in slaveholding states, will give you a far more graphic idea of what slavery actually is, than you have from Uncle Tom's Cabin; for there the most horrible features are softened. This writer says, 'And now a word on American representatives abroad. I have already made my complaint of the troubles brought on Americans here by that "incendiary" book of Mrs. Stowe's, especially of the difficulty we have in making the French understand our institutions. But there was one partially satisfactory way of answering their questions, by saying that Uncle Tom's Cabin was a romance. And this would have served the purpose pretty well, and spared our blushes for the model republic, if the slaveholders themselves would only withhold their testimony to the truth of what we were willing to let pass as fiction. But they are worse than Mrs. Stowe herself, and their writings are getting to be quoted here quite extensively. The Moniteur of to-day, and another widely-circulated journal that lies on my table, both contain extracts from those extremely incendiary periodicals, The National Intelligencer, of February 11, and The N.O. Picayune, of February 17. The first gives an auctioneer's advertisement of the sale of "a negro boy of eighteen years, a negro girl aged sixteen, three horses, saddles, bridles, wheelbarrows," &c. Then follows an account of the sale, which reads very much like the description, in the dramatic feuilletons here, of a famous scene in the Case de l'Oncle Tom, as played at the Ambigu Comique. The second extract is the advertisement of "our esteemed fellow-citizen, Mr. M.C.G.," who presents his "respects to the inhabitants of O. and the neighbouring parishes," and "informs them that he keeps a fine pack of dogs trained to catch negroes," &c. It is painful to think that there are men in our country who will write, and that there are others found to publish, such tales as these about our peculiar institution. I put it to Mr. G., if he thinks it is patriotic. As a "fellow-citizen," and in his private relations, G. may be an estimable man, for aught I know, a Christian and a scholar, and an ornament to the social circles of O. and the neighboring parishes. But as an author, G. becomes public property, and a fair theme for criticism; and in that capacity, I say G. is publishing the shame of his country. I call him G., without the prefatory Mister, not from any personal disrespect, much as I am grieved at his course as a writer, but because he is now breveted for immortality, and goes down to posterity, like other immortals, without titular prefix.' [Cheers.] Now, here is where you get the true features of slavery. What is the reason that the churches, as a general thing, are silent—that some of them are apologists, and that some, in the extreme Southern States, actually defend slavery, and say it is a good institution, and sanctioned by Scripture? It is simply this—the overwhelming power of the slave system; and whence comes that overwhelming power? It comes from its great influence in the commercial world. [Hear!] Until the time that cotton became so extensively an article of export, there was not a word said in defence of slavery, as far as I know, in the United States. In 1818, the Presbyterian General Assembly passed resolutions unanimously on the subject of slavery, to which this resolution is mildness itself; and not a man could be found to say one word against it. But cotton became a most valuable article of export. In one form and another, it became intimately associated with the commercial affairs of the whole country. The northern manufacturers were intimately connected with this cotton trade, and more than two thirds raised in the United States has been sold in Great Britain; and it is this cotton trade that supports the whole system. That you may rely upon. The sugar and rice, so far as the United States are concerned, are but small interests. The system is supported by this cotton trade, and within two days I have seen an article written with vigor in the Charleston Mercury, a southern paper of great influence, saying, that the slaveholders are becoming isolated, by the force of public opinion, from the rest of the world. They are beginning to be regarded as inhuman tyrants, and the slaves the victims of their cruelty; but, says the writer, just so long as you take our cotton, we shall have our slaves. Now, you are as really involved in this matter as we are—[Hear, hear!]—and if you have no other right to speak on the subject, you have a right to speak from being yourselves very active participators in the wrong. You have a great deal of feeling on the subject, honorable and generous feeling, I know—an earnest, philanthropic, Christian feeling; but if you have nothing to do, that feeling will all evaporate, and leave an apathy behind. Now, here is something to be done. It may be a small beginning, but, as you go forward, Providence will develop other plans, and the more you do, the further you will see. I am happy to know that a beginning has been made. There are indications that a way has been so opened in providence that this exigency can be met. Within the last few years, the Chinese have begun to emigrate to the western parts of the United States. They will maintain themselves on small wages; and wherever they come into actual competition with slave labor, it cannot compete with them. Very many of the slaveholders have spoken of this as a very remarkable indication. If slavery had been confined to the original slave states, as it was intended, slavery could not have lived. It was the intention that it should never go beyond those boundaries. Had this been the case, it would increase the number of slaves so much that they would have been valueless as articles of property. I must say this for America, that the slaves increase in the slave states faster than the white people; and it shows that their physical condition is better than was that of the slaves at the West Indies, or in Cuba, where the number actually diminished. We must have more slave territories to make our slaves valuable, and there was the origin of that iniquitous Mexican war, whereby was added the vast territory of Texas; and then it was the intention to make California a slave state; but, I am happy to say, it has been received into the Union as a free state, and God grant it may continue so. [Hear, hear!] What has been the effect of this expansion of slave territory? It has doubled the value of slaves. Since I can remember, a strong slave man would sell for about four hundred or six hundred dollars—that is, about one hundred pounds; but now, during the present season, I have known instances in which a slave man has been sold for two hundred and thirty pounds. There are more slaves raised in Virginia and Maryland than they can use in those states in labor, and, therefore, they sell them at one hundred, two hundred, or three hundred pounds, as the case may be, for cash. All that Mrs. Tyler intimates in that letter about slavery in America, and the impression it is calculated and intended to convey, that they treat their slaves so well, and do not separate their families, and so forth, is all mere humbug. [Laughter and cheers.] It is well known that Virginia has more profit from selling negroes than from any other source. The great sources of profit are tobacco and negroes, and they derive more from the sale of negroes than tobacco. You see the temptation this gives to avarice. Suppose there is a man with no property, except fifteen or twenty negro men, whom he can sell, each one for two hundred pounds, cash; and he has as many negro women, whom he can sell for one hundred and fifty pounds, cash, and the children for one hundred pounds each: here is a temptation to avarice; and it is calculated to silence the voice of conscience; and it is the expansion of the slave territory, and the immense mercantile value of the cotton, that has brought so powerful an influence to bear on the United States in favor of slavery. [Hear, hear.] Now, as to free labor coming into competition with slave labor: You will see, that when the price of slaves is so enormous, it requires an immense outlay to stock a plantation. A good plantation would take two hundred, or three hundred hands. Now, say for every hand employed on this plantation, the man must pay on an average two hundred pounds, which is not exorbitant at the present time. If he has to pay at this rate, what an immense outlay of capital to begin with, and how great the interest on that sum continually accumulating! And then there is the constant exposure to loss. These plantation negroes are very careless of life, and often cholera gets among them, and sweeps off twenty-five or thirty in a few days; and then there is the underground railroad, and, with all the precautions that can be taken, it continues to work. And now you see what an immense risk, and exposure to loss, and a vast outlay of capital, there is in connection with this system. But, if a man takes a cotton farm, and can employ Chinese laborers, he can get them for one or two shillings a day, and they will do the work as well, if not better than negroes, and there is no outlay or risk. [Hear, hear!]. If good cotton fields can be obtained, as they may in time, here is an opening which will tend to weaken the slave system. If Christians will investigate this subject, and if philanthropists generally will pursue these inquiries in an honest spirit, it is not long before we shall see a movement throughout the civilized world, and the upholders of slavery will feel, where they feel most acutely—in their pockets. Until something of this kind is done, I despair of accomplishing any great amount of good by simple appeals to the conscience and right principle. There
