If these opinions of well-prepared persons, dispersed through the slave States, and entrusted with the public advocacy of their interests, do not betoken that slavery is tottering to its fall, there are no such things as signs of the times.

The prohibition of books containing anything against slavery, has proceeded to a great length. Last year, Mrs. Barbauld's works were sent back into the north by the southern booksellers, because the "Evenings at Home" contain a "Dialogue between Master and Slave." Miss Sedgwick's last novel, "The Linwoods," was treated in the same way, on account of a single sentence about slavery. The "Tales of the Woods and Fields," and other English books, have shared the same fate. I had a letter from a Southern lady, containing some regrets upon the necessity of such an exclusion of literature, but urging that it was a matter of principle to guard from attacks "an institution ordained by the favour of God for the happiness of man:" and assuring me that the literary resources of South Carolina were rapidly improving.—So they had need; for almost all the books already in existence will have to be prohibited, if nothing condemnatory of slavery is to be circulated. This attempt to nullify literature was followed up by a threat to refuse permission to the mails to pass through South Carolina: an arrangement which would afflict its inhabitants more than it could injure any one else.

The object of all this is to keep the children in the dark about how the institution is regarded abroad. This was evident to me at every step: and I received an express caution not to communicate my disapprobation of slavery to the children of one family, who could not, their parents declare, even feel the force of my objections. One of them was "employed, the whole afternoon, in dressing out little Nancy for an evening party; and she sees the slaves much freer than herself." Of course, the blindness of this policy will be its speedy destruction. It is found that the effect of public opinion on the subject upon young men who visit the northern States, is tremendous, when they become aware of it: as every student in the colleges of the north can bear witness. I know of one, an heir of slaves, who declared, on reading Dr. Channing's "Slavery," that if it could be proved that negroes are more than a link between man and brute, the rest follows of course, and he must liberate all his. Happily, he is in the way of evidence that negroes are actually and altogether human.

The students of Lane Seminary, near Cincinnati, of which Dr. Beecher is the president, became interested in the subject, three or four years ago, and formed themselves into an Abolition Society, debating the question, and taking in newspapers. This was prohibited by the tutors, but persevered in by the young men, who conceived that this was a matter with which the professors had no right to meddle. Banishment was decreed; and all submitted to expulsion but fourteen. Of course, each of the dispersed young men became the nucleus of an Abolition Society, and gained influence by persecution. It was necessary for them to provide means to finish their education. One of them, Amos Dresser, itinerated, (as is usual in the sparsely-peopled west,) travelling in a gig, and selling Scott's Bible, to raise money for his educational purposes. He reached Nashville, in Tennessee; and there fell under suspicion of abolition treason; his baggage being searched, and a whole abolition newspaper, and a part of another being found among the packing-stuff of his stock of bibles. There was also an unsubstantiated rumour of his having been seen conversing with slaves. He was brought to trial by the Committee of Vigilance; seven elders of the presbyterian church at Nashville being among his judges. After much debate as to whether he should be hanged, or flogged with more or fewer lashes, he was condemned to receive twenty lashes, with a cow-hide, in the market-place of Nashville. He was immediately conducted there, made to kneel down on the flint pavement, and punished according to his sentence; the mayor of Nashville presiding, and the public executioner being the agent. He was warned to leave the city within twenty-four hours: but was told, by some charitable person who had the bravery to take him in, wash his stripes, and furnish him with a disguise, that it would not be safe to remain so long. He stole away immediately, in his dreadful condition, on foot; and when his story was authenticated, had heard nothing of his horse, gig, and bibles, which he values at three hundred dollars. Let no one, on this, tremble for republican freedom. Outrages upon it, like the above, are but extremely transient signs of the times. They no more betoken the permanent condition of the republic, than the shivering of one hour of ague exhibits the usual state of the human body.

The other young men found educational and other assistance immediately; and a set of noble institutions has grown out of their persecution. There were professors ready to help them; and a gentleman gave them a farm in Ohio, on which to begin a manual labour college, called the Oberlin Institute. It is on a most liberal plan young women who wish to become qualified for "Christian teaching" being admitted; and there being no prejudice of colour. They have a sprinkling both of Indians and of negroes. They do all the farm and house work, and as much study besides as is good for them. Some of the young women are already fair Hebrew and Greek scholars. In a little while, the estate was so crowded, and the new applications were so overpowering, that they were glad to accept the gift of another farm. When I left the country, within three years from their commencement, they had either four or five flourishing institutions in Ohio and Michigan, while the Lane Seminary drags on feebly with its array of tutors, and dearth of pupils. A fact so full of vitality as this will overbear a hundred less cheering signs of the times. A very safe repose may be found in the will of the majority, wherever it acts amidst light and freedom.

Just before I reached Mobile, two men were burned alive there, in a slow fire, in the open air, in the presence of the gentlemen of the city generally. No word was breathed of the transaction in the newspapers: and this is the special reason why I cite it as a sign of the times; of the suppression of fact and repression of opinion which, from the impossibility of their being long maintained, are found immediately to precede the changes they are meant to obviate. Some months afterwards, an obscure intimation of something of the kind having happened appeared in a northern newspaper; but a dead silence was at the time preserved upon what was, in fact, the deed of a multitude. The way that I came to know it was this. A lady of Mobile was opening her noble and true heart to me on the horrors and vices of the system under which she and her family were suffering in mind, body, and estate. In speaking of her duties as head of a family, she had occasion to mention the trouble caused by the licentiousness of the whites, among the negro women. It was dreadful to hear the facts which had occurred in her own household; and the bare imagination of what is inflicted on the negro husbands and fathers was almost too much to be borne. I asked the question, "Does it never enter the heads of negro husbands and fathers to retaliate?" "Yes, it does." "What follows?" "They are murdered,—burned alive." And then followed the story of what had lately happened. A little girl, and her still younger brother, one day failed to return from school, and never were seen again. It was not till after all search had been relinquished, that the severed head of the little girl was found in a brook, on the borders of a plantation. Circumstances were discovered that left no doubt that the murders were committed to conceal violence which had been offered to the girl. Soon after, two young ladies of the city rode in that direction, and got off their horses to amuse themselves. They were seized upon by two slaves of the neighbouring plantation; but effected their escape in safety, though with great difficulty. Their agitation prevented their concealing the fact; and the conclusion was immediately drawn that these men were the murderers of the children. The gentlemen of Mobile turned out; seized the men; heaped up faggots on the margin of the brook, and slowly burned them to death. No prudish excuses for the suppression of this story will serve any purpose with those who have been on the spot, any more than the outcry about "amalgamation," raised against the abolitionists by those who live in the deepest sinks of a licentiousness of which the foes of slavery do not dream. No deprecatory plea regarding propriety or decency will pass for anything but hypocrisy with those who know what the laws against the press are in the south-west, and what are the morals of slavery in its palmy state. I charge the silence of Mobile about this murder on its fears; as confidently as I charge the brutality of the victims upon its crimes.

Notwithstanding the many symptoms of an unmanly and anti-republican fear which met my observation in these regions, it was long before I could comprehend the extent of it; especially as I heard daily that the true enthusiastic love of freedom could exist in a republic, only in the presence of a servile class. I am persuaded that the southerners verily believe this; that they actually imagine their northern brethren living in an exceedingly humdrum way, for fear of losing their equality. It is true that there is far too much subservience to opinion in the northern States: particularly in New England. There is there a self-imposed bondage which must be outgrown. But this is no more like the fear which prevails in the south than the apprehensiveness of a court-physician is like the terrors of Tiberius Cæsar.

I was at the French theatre at New Orleans. The party with whom I went determined to stay for the after-piece. The first scene of the after-piece was dumb-show; so much noise was made by one single whistle in the pit. The curtain was dropped, and the piece re-commenced. The whistling continued; and, at one movement, the whole audience rose and went home. I was certain that there was something more in this than was apparent to the observation of a stranger. I resolved to find it out, and succeeded. The band was wanted from the orchestra, to serenade a United States senator who was then in the city; and one or two young men were resolved to break up our amusement for the purpose of releasing the band. But why were they allowed to do this? Why was the whole audience to submit to the pleasure of one whistler? Why, in New Orleans it is thought best to run no risk of any disturbance. People there always hie home directly when things do not go off quite quietly.

It is the same, wherever the blacks outnumber the whites, or their bondage is particularly severe. At Charleston, when a fire breaks out, the gentlemen all go home on the ringing of the alarm-bell; the ladies rise and dress themselves and their children. It may be the signal of insurrection: and the fire burns on, for any help the citizens give, till a battalion of soldiers marches down to put it out.
