I am apprehensive that many of your readers, who feel a lively interest in the welfare of the slaves, are not correctly and fully informed as to their amount of religious instruction. From the speeches of Mr. Thompson and others, they might be led to believe that slaves in our Southern States never read a Bible, hear a gospel sermon, or partake of a gospel ordinance. It is to be hoped, however, that little credit will be given to such misrepresentations, notwithstanding the zeal and industry with which they are disseminated.

What has been done on a single plantation.

I will now inform your readers what has been done, and is now doing, for the moral and religious improvement of the slaves on a single plantation, with which I am well acquainted, and these few facts may serve as a commentary on the unsupported assertions of Mr. Thompson and others. And here I could wish that all who are so ready to denounce every man that is so unfortunate as to be born to a heritage of slaves, could go to that plantation, and see with their own eyes, and hear with their own ears, the things which I despair of adequately describing. Truly, I think they would be more inclined, and better qualified to use those weapons of light and love which have been so ably and justly commended to their hands.

On this plantation there are from 150 to 200 slaves, the finest looking body that I have seen on any estate. Their master and mistress have felt for years how solemn are the responsibilities connected with such a charge; and they have not shrunk from meeting them. The means used for their spiritual good, are abundant. They enjoy the constant preaching of the gospel. A young minister of the Presbyterian church, who has received a regular collegiate and theological education, is laboring among them, and derives his entire support from the master, with the exception of a trifling sum which he receives for preaching one Sabbath in each month for a neighboring church. On the Sabbath, and during the week, you may see them filling the place of worship, from the man of grey hairs to the small child, all neatly and comfortably clothed, listening with respectful, and in many cases, eager attention to the truth as it is in Jesus, delivered in terms adapted to their capacities, and in a manner suited to their peculiar habits, feelings and circumstances; engaging with solemnity and propriety in the solemn exercise of prayer, and mingling their melodious voices in the hymn of praise. Sitting among them are the white members of the family encouraging them by their attendance, manifesting their interest in the exercises, and their anxiety for the eternal well-being of their people. Of the whole number, forty-five or fifty have made a profession of religion, and others are evidently deeply concerned.

Let me now conduct you to a Bible class of ten or twelve adults who can read, met with their Bibles to study and have explained to them the word of God. They give unequivocal demonstrations of much interest in their employment, and of an earnest desire to understand and remember what they read. From hence we will go to another room, where are assembled eighteen to twenty lads, attending upon catechetical instruction, conducted by their young master. Here you will notice many intelligent countenances, and will be struck with the promptitude and correctness of their answers.

But the most interesting spectacle is yet before you. It is to be witnessed in the Infant School Room, nicely fitted up and supplied with the customary cards and other appurtenances. Here every day in the week, you may find twenty-five or thirty children, neatly clad and wearing bright and happy faces. And as you notice their correct deportment, hear their unhesitating replies to the questions proposed, and above all when they unite their sweet voices in their touching songs, if your heart is not affected and your eyes do not fill, you are the hardest-hearted and driest-eyed visitor that has ever been there. But who is their teacher? Their mistress, a lady whose amiable Christian character and most gifted and accomplished mind and manners are surpassed by none. From day to day, month to month, and year to year, she has cheerfully left her splendid halls and circle of friends, to visit her school room, where, standing up before those young immortals, she trains them in the way in which they should go, and leads them to Him who said, "suffer little children to come unto me."

From the Infant School room, we will walk through a beautiful lawn half a mile, to a pleasant grove commanding a view of miles in extent. Here is a brick chapel, rising for the accommodation of this interesting family; sufficiently large to receive two or three hundred hearers. When completed, in beauty and convenience it will be surpassed by few churches in the Southern country.

On the plantation you might also see other things of great interest. Here a negro is the overseer. Marriages are regularly contracted. No negro is sold, except as a punishment for bad behavior, and a dreaded one it is. None is bought, save for the purpose of uniting families. Here you will near no clanking of chains, no cracking of whips; (I have never seen a blow struck on the estate,) and here last, but not least, you will find a flourishing Temperance Society, embracing almost every individual on the premises. And yet the "Christianity of the South is a chain-forging, a whip-plaiting, marriage discouraging, Bible-withholding Christianity!"

I have confined myself to a single plantation. But I might add many most interesting facts in regard to others, and the state of feeling in general, but I forbear.

Yours, &c
