But before I left this school, a dark, bronzed, and severe-looking man came in one day, and I was called out of class to work a problem on the blackboard for him. I suppose it was done fairly, for I went back to the class thrilling with the touch of Dr. Livingstone. He had said something to me, and placed his hand on my head. I never knew what he said, but I felt his hand, and my heart and pulses beat the faster. Now, if I had been a good boy, I should have been inspired by that touch, and have decided then and there to become a missionary, but truth compels me to say that I was not a good boy, and did not feel called to the missionary field; but I did feel inspired--I felt certain that I could kill lions. But after all, you see, I am in the direct line of succession. A great missionary’s hand has been laid upon my head, and not ‘all the water in the rough, rude sea can wash away the balm.’ But that was not the reason why I became a missionary; in fact, there was no particular reason why I should, but there was a long chain of circumstances, a series of events looking small enough in themselves at the time, but, seen in the light of experience, to me large and important events. But who shall say what is great or small in our lives’ history? It was a small thing that led me to a night-school, and to teach there for years after a hard, long day’s work, but I did it. Temperance societies, literary societies, mutual improvement societies are small things, but I worked hard for them all; and if I did not do a lot of good to others, I did some good to myself; if I could not teach much, I could learn a lot. It was a small thing that led me to take a men’s Bible class in a purely Welsh-speaking district on Sunday afternoons, but it altered the course of my life, made a missionary of me against my will, and brought me to London to write this book.
