It would have puzzled any one to have told what sermon nature preached to that merry party, as they wandered through green fields and quiet lanes, talking upon a hundred different subjects, and making the calm Sabbath morn ring with the strains of their laughter.

"Your idea of creation's voice is better in theory than in practice," George said, when they returned home. "Can any of you tell me what the text was which nature took to preach from, for I have no distinct remembrance of it?"

"The text seemed to me to be this," said Dixon, "that 'to everything there is a season, and a time to every purpose under the heavens—a time to weep and a time to laugh—a time to keep silence and a time to speak;' and the application was, that we had chosen the right time for enjoying much speaking and much laughing."

The afternoon was not spent as George had been accustomed to spend it. Light, frivolous conversation, and still more dangerous debate upon religious subjects, without religious feeling, occupied the time, and George felt glad when the evening came, and they started off together to hear a popular preacher, whose merits they had been discussing during the afternoon.

On their way thither they passed a large building, into which several people were entering, and as the outside of the place was ornamented with handbills, they paused to read them. They ran thus:—

"HALL OF SCIENCE.—A Lecture will be delivered in this Hall on Sunday evening, at half past six, by Professor Martin, on 'The Uses of Reason.' Young men are cordially invited to attend.

"What is truth? Search and see."

"Do you know anything of this Professor Martin?" asked Dixon. "Is he worth hearing?"

"A friend of mine told me he had heard him, a little while ago, and was never better pleased with any lecture," Ashton answered. "Shall we put up here for the evening?"

"Is he a preacher, or a mere lecturer?" asked George. The question attracted the attention of a person entering the Hall; and, turning to George, he answered:—

"Professor Martin is one of those best of all preachers. He can interest without sending you to sleep, and his discourses are full of sound wisdom. He is a lover of truth, and advocates the only way to arrive at it, which is by unfettered thought. In his lectures he puts his theory into practice by freely expressing his unfettered thoughts. I have seats in the front of the lecture-room; if you will favour me by accepting them, they are at your service."
