"MY DEAR SIR,--I send you a scroll sketch of instructions, or hints rather, for your guidance in your important mission, _but your own judgment_ and good sense will be the best guides. You are called at an early period of life to a most important duty, and on the manner in which you shall discharge it will depend, under God, the position which we as a Church may be called upon to occupy in regard to the progress of Christ's kingdom in these western regions. You will find in Bishop Anderson a pious and liberal Episcopalian and a Bishop--yea, _The Bishop_! You know what I mean. Already you know something of Popery and its steps, open or close. The Sabbath observance subject I commend to your serious notice. The company like hunting on the Lord's day! The range is wide and long; but if you can get from the United States boundary to York Fort, it will be desirable. Your object being exploratory keep note of all. Preach and exhort and expound, and conduct devotional exercises wherever you have an opportunity--Sabbath days especially. * * * * "Our prayers will accompany you, and our most fervent desires that your way may be prospered before you, and that you may be hailed by the settlers as a messenger of good tidings and a pioneer of salvation. "Come up as soon as you can. "Yours, etc., "ROBT. BURNS." The young missionary engrossed in his French Canadian work received this communication. He was at the same time earnestly sought for by the congregation of North Georgetown in Lower Canada. After due consideration, he refused Dr. Burns' offer to go to Red River. He did this not because he was lacking in the true spirit of the missionary, but because he felt anxious about his old father and mother still alive in New York State. They were now left without any of their children beside them, and John Black, as their eldest son, felt it to be his duty to be within reach of them. He therefore felt justified in declining the earnest call to visit the Northwest. It is stated that on his refusal application was made to one who has since become known as one of the staunchest theologians and best preachers of the Church, the Rev. Professor MacLaren, D.D., of Knox College, Toronto. He, however, was not able to accept. Very strong pressure was again brought to bear upon John Black, and as the season was advancing his answer had to be given without delay. The following letter written to his brother explains his action in the matter: ON TO RED RIVER. Toronto, July 31st, 1851.
