15. In the year 1857, towards the close of the summer, I left my home in Nebraska for a time, and went eastward on a lecturing tour. My first appointment was at East Liverpool, in Ohio. There I met with my good, old friend John Donaldson, of Byker, near Newcastle-on-Tyne, England. He spoke of days long past, when we worked together in the cause of Christ. He was kind, as he had always been; but it troubled him to find me so changed--so far estranged from the views of former times. Though glad to see my friend, the memories which his presence revived, of the days when I was a happy and a useful minister of Christ, and the partial re-awakening of old religious thoughts and feelings which it occasioned, made me feel, for a moment, an indescribable sensation, as of one who had got an unlooked-for glimpse of some fearful loss he had sustained, or of some tremendous mistake he had committed. My infidel logic, however, hastened to my aid, and assured me I was right; but the deep and deathless instincts of my soul were not entirely at rest. I reached Philadelphia at length. There I was engaged by Dr. W. Wright for eight months. I lectured every Sunday, sometimes on theological, sometimes on moral, and sometimes on scientific and general subjects. I always urged on my hearers a virtuous life, and did what I could to escape the society of persons of immoral habits. And I thought, for a time, I had succeeded. But I was grievously mistaken. One of the acting men in my congregation was a Plymouth man. He, as I afterwards found, had deserted his wife and family, and was living with another woman. Another, a more important member of my congregation, whom I supposed to be an example of propriety, turned out to be an advocate of unlimited license. And another, a man of great wealth, who had often invited me to his house, and shown me kindness in other ways, I found, after his death, had never been married to the person with whom he had lived as his wife. I also found that he had another family in another part of the city. I mention these unpleasant matters to show, that facts were not wanting to shake my faith in the moral influence of infidel principles. The gentleman by whom I was employed, treated me with great respect and kindness, and some of my congregation did what they could to make me comfortable; but the longer I remained in my position, the less encouragement I saw to expect infidelity or skepticism to produce a virtuous and honorable life. The gentleman by whom I was employed had thought of expending some fifty thousand dollars in building a hall, and endowing a lecture, &c., for the propagation of infidel principles; but the conduct of the skeptics that gathered round him, soon cured him of his anti-christian zeal.
