I hereby certify that the bearer, Mr. Wm. B. Mackay, has taught the Congregational School of the Free Church here for nearly two years, with diligence, efficiency, and acceptance; that he has during that time maintained an unexceptionable and consistent moral and religious character; and that I regret exceedingly that owing to delicate health he is under the necessity of resigning his charge and proceeding to a warmer climate. I have much pleasure in recommending him as one capable of being a useful, intelligent, and agreeable member of society wherever his lot may be cast.
