I am aware that the secretary and the agents of the tract societies make very encouraging reports of the results of their operations. I am always interested in these details, and do not discredit at all the statements which they make. Nay, I am convinced that in certain departments of their effort they are successful in doing much good. I believe that their noble army of colporteurs, going from lonely neighborhood to neighborhood, and carrying with them an unselfish, devoted life, and the living voice of prayer, exhortation, and counsel, win many souls to Christian virtue. I am willing to acknowledge, further, that here and there a tract, chance-sown, may fall into ground ready to receive it; but I have a right to question whether the same outlay of effort and money, applied directly in other fields, would not bring very much larger returns. My point is that in all efforts to do good, in this way, appropriateness of time and place is always to be consulted. I once took my seat in a dentist's chair to have an operation performed upon my teeth. If I remember correctly, an ugly fang was to be removed,--at any rate, pain was involved in the matter; but no sooner was the dentist's arm around my head, and his instrument in my mouth, than the well-meaning and zealous operator began to question me upon the subject of personal religion. Now it seemed quite as bad to undertake to propagate Christianity at the point of a surgical instrument, as it would be to win proselytes by the sword; and the utter incongruity of the two operations disgusted me. At any rate, _I changed my dentist_. I felt like the man who found upon his landlady's table an article of butter that was inconveniently encumbered with hair, and who informed her that he had no objection to hair, but would prefer to have it served upon a separate dish.
