IN reply to many requests from those ministers who in their student days listened to my lectures, I submit a selection to the press. This, however, I cannot do without an apology, for these addresses were not originally prepared for the public eye, and are scarcely presentable for criticism. My College lectures are colloquial, familiar, full of anecdote, and often humorous: they are purposely made so, to suit the occasion. At the end of the week I meet the students, and find them weary with sterner studies, and I judge it best to be as lively and interesting in my prelections as I well can be. They have had their fill of classics, mathematics, and divinity, and are only in a condition to receive something which will attract and secure their attention, and fire their hearts. Our reverend tutor, Mr. Rogers, compares my Friday work to the sharpening of the pin: the fashioning of the head, the straightening, the laying on of the metal and the polishing have been done during the week, and then the process concludes with an efiort to give point and sharpness. To succeed in this the lecturer must not be dull himself, nor demand any great effort from his audience. I am as much at home with my young brethren as in the bosom of my family, and therefore speak without restraint. Generous minds will take this into account in reading these lectures, and I shall hope that all who favour me with their criticisms will be of that noble order.
