"We have not time to-day," said Mr. Wilton, "to fix on the particular line of study which we shall follow. Of course we cannot examine all the works of Nature, and study every science, and trace the footprints of the Creator in every place where he has walked; we must fix on some small part of the works of God, and direct our attention closely to that. We shall find this course more profitable than roaming carelessly over a much larger space. Our next lesson will have to be a general one--a kind of preface to what shall come after. In the mean while, you can be collecting your thoughts upon the subject, and calling to mind anything that you have read bearing upon the handiwork of God manifest in Nature." The school closed, and as the scholars pass out let me introduce to you the members of the pastor's class. This class was small for several reasons. The church to which Mr. Wilton preached was not the popular church. The fashionable people and all who loved popularity and drifted with the tide went to another church. Careless, thoughtless young people naturally went with the crowd, and of those who attended his church some did not care to join his class. He was too much in earnest to please them. He made religion a reality, and his instruction compelled them to think, and of course those who did not like to think were not well pleased with him. But there were a few of the young men who were greatly interested in his instructions. They were earnest readers of instructive books; they liked conversation which called out thought; they were most of all pleased with questions and themes which gave them new ideas. Indeed, in the community, there were two classes of persons who held Mr. Wilton in the highest esteem and regard: one of these was composed of men and women of earnest, intelligent piety, experienced Christians; the other, of those who were not Christians, but who respected sincerity and disinterested godliness, and liked sermons filled with meat and marrow.
