I have very much pleasure in bearing testimony to Mr. Mackay's efficiency as a public teacher of youth. His manner in communicating instruction is particularly calculated to facilitate the development of the youthful mind. His discipline is both firm and mild. Suffice it to say that he taught successively for thirteen years two of the most numerously attended schools in this county, and that during that time he maintained the highest character as a faithful, conscientious, and efficient teacher. In every department of school exercise he appears to be at home, and the progress made by his pupils in the knowledge of English, page 7 writing, arithmetic, mathematics, Latin, and Greek, indicates that he knows how to teach.
