Thomas had joined himself to God's people but a short time, when he determined, by the advice and invitation of his friends, to become a Sabbath-school teacher. His experience and success in this sphere of labor will be best described in his own words: "Soon after my union with the Wesleyans, I became a teacher in the Sunday-school, which, at that time, was not very prosperous. Here, as teacher of one of the junior classes, I strove to do my duty to God and the children placed under my care. A few of our teachers determined to establish a school at I----, a small village about two miles distance from H----, in which the Wesleyans had preaching at a private house, and a class of five members, to whom I willingly gave my assistance. But where should we get a room? was the next question to be solved. After some difficulty on this point, we got the use of an old barn; but which, by the way, had no window in it, and was consequently so dark, that we were obliged to keep the door constantly open, and, it being winter season, we found it very cold. Yet even this was too good to last long, for we were soon told that we could not have the barn any longer, and we were, therefore, obliged to look out for another place. Our next remove was to a different part of the village, to a room over some stables, the floor of which, besides having sundry large holes in it, was so rotten that we were obliged to range the children around by the walls, fearing lest the floor should give way from their weight, if placed in the centre. Even in such a place as this, our school increased from twenty to forty.
