N. B.--That Mrs. Child, when she became an Abolitionist, did not become a woman “of one idea” is evinced, not only by her two volumes of enchanting “Letters from New York,” “Memoirs of Madame de Staël” and “Madame Roland,” “Biographies of Good Wives,” and several exquisite books for children, but still more by her three octavo volumes, entitled “Progress of Religious Ideas,” which must have been the result of a vast amount of reading and profound thought on all the subjects of theology and religion. Her later work, “Looking towards Sunset,” is full of beautiful ideas about that future life, for which her untiring devotion to all the humanities in this life must have so fully prepared her. ERUPTION OF LANE SEMINARY. Lane Seminary was an institution established by our orthodox fellow-Christians, mainly for the preparation of young men for the ministry. It attained so much importance in the estimation of its patrons, that, in 1832, they claimed for it the services and the reputation of Rev. Dr. Beecher, who left Boston at that time and became its president. There he found, or was soon after joined by, Prof. Calvin E. Stowe, another distinguished teacher of Calvinistic theology. This school of the prophets was placed on Walnut Hill, in the vicinity of Cincinnati, that it might be near to the Southwestern States, and was separated from Kentucky only by the river Ohio. It had attracted, by the reputation of its Faculty, from all parts of the country, quite a number of remarkably able, earnest, conscientious, and, as they proved to be, eloquent young men. At the time when the signal event occurred of which I am now to give some account, there were in the literary and theological departments of Lane Seminary more than a hundred students. Eleven of these were from different slave States; seven of them sons of slaveholders, one himself a slaveholder when he entered the institution, and one of the number--James Bradley--had emancipated himself from the cruel bondage by the payment of a large sum, that he had earned by extra labor. Besides these, there were ten of the students who had resided more or less in the slave States, and were well acquainted with the condition of the people, and the influence of their “peculiar institution” of domestic servitude. Moreover, that you may appreciate fully the importance of the event I am going to narrate to you, and know that it was not (as some at the time represented it to be) a boyish prank, or mere college rebellion,--“a tempest in a teapot,”--let me tell you that the youngest student in the seminary was nineteen years of age, most of the students were more than twenty-six years old, and several of them were over thirty. They were sober, Christian men, who were preparing themselves, in good earnest, to preach the Gospel; and they believed that one of its proclamations was “liberty to the captives, let the oppressed go free, break every yoke.”
