Notwithstanding the earnestness of these entreaties, I felt compelled to retire from this work. No one could appreciate its importance more highly than, from my personal knowledge of its needs, I did. But for more than ten years since my graduation from the theological seminary, I had been constantly "on the wing." As stated in my opening chapter, I had spent five years as an invalid wanderer. I had roamed over the Southern States nearly a year, had made two visits to the Island of Hayti, and spent a second winter in the South. I had then entered upon these itinerant labors, in which I had spent nearly five years more. I was not weary of the work, but I wanted change; I sighed for rest and an opportunity to study--to commune again with my beloved books that had remained unopened during all these years. In addition to these personal desires, my labors had revealed the imperative demand for the liberal education of as many as possible of the young men in the wide region I had so thoroughly explored; and a large number of my "many friends" had signified to me their strong desire to place their sons in the college should I accept the appointment. I therefore wrote my resignation, as follows: Louisville, Kentucky, _July 12, 1858_. Rev. James H. McNeill, _Secretary of the American Bible Society, New York_. My dear Brother: I have already informed you that I had been elected President and Professor of Mental and Moral Philosophy in Cumberland College, Princeton, Kentucky. After mature and prayerful consideration of the whole subject, I have decided to accept the appointment; and I therefore resign my commission as Agent of the American Bible Society for Western Kentucky. It is not without deep emotion that I thus sunder my official connection with this noble institution. For nearly five years I have labored to promote its interests, and during this entire period all my correspondence and intercourse with its different officers has been of the most pleasant character. I can not recall a single word or act that has marred the harmony of our relations. The field assigned me is very large--with meager facilities for traveling--and on this account my duties have been very laborious. I have again and again _ridden on horseback_ over all the counties southward from this city to the Tennessee line, and westward to the Mississippi River. I have preached repeatedly in all of them, solicited donations, secured colporteurs, ordered Bibles for them, and made full arrangements to have all the families visited, and every destitute household supplied with the inestimable Word by sale or gift. I have thus ridden thousands of miles over the roughest roads, exposed to every variety of weather.
