Moreover, the chief work of my life has been the part I have been permitted, by the good Lord, to have in giving the entire Bible to the Sioux Nation. This book is only "the band of the sheaf." If, by weaving the principal facts of our Missionary work, its trials and joys, its discouragements and grand successes, into this personal narrative of "MARY AND I," a better judgment of Indian capabilities is secured, and a more earnest and intelligent determination to work for their Christianization and final Citizenship, I shall be quite satisfied. Since the historical close of "Forty years with the Sioux," some important events have transpired, in connection with our missionary work, which are grouped together in an Appendix, in the form of Monographs. S. R. R. BELOIT, Wis., January, 1880. NOTE:--This book, first published by the author, though with the imprint of W. G. Holmes, Chicago, has met with such favor as to indicate that it should be brought out under auspices that would give it to a larger circle of those interested in Indian missions. And to carry on the life of its author to its close, and give a more complete view of the progress of the work, another chapter has been added, making the "Forty Years" Fifty Years with the Sioux. A. L. R. INTRODUCTION. The churches owe a great debt of gratitude to their missionaries, first, for the noble work they do, and, second, for the inspiring narratives they write. There is no class of writings more quickening to piety at home than the sober narratives of these labors abroad. The faith and zeal, the wisdom and patience, the enterprise and courage, the self-sacrifice and Christian peace which they record, as well as the wonderful triumphs of grace and the simplicity of native piety which they make known, bring us nearer, perhaps, to the spirit and the scenes of Apostolic times than any other class of literature. How the churches could, or can ever, dispense with the reactionary influence from the Foreign Mission field, it is difficult to understand. Doubtless, however, when the harvest is all gathered, the Lord of the Harvest will, in his wisdom, know how to supply the lack. Some narratives are valuable chiefly for their interest of style and manner, while the facts themselves are of minor account. Other narratives secure attention by the weight of their facts alone. The author of "Mary and I; Forty Years with the Sioux" has our thanks for giving us a story attractive alike from the present significance of its theme and from the frank and fresh simplicity of its method.
