And yet it is not certain that this period of immense gifts of money is really a period of increased liberality in the church from the time, thirty or forty years before, when a millionaire was a rarity to be pointed out on the streets, and the possession of a hundred thousand dollars gave one a place among "The Rich Men of New York." In 1850 the total wealth of the United States was reported in the census as seven billions of dollars. In 1870, after twenty years, it had more than fourfolded, rising to thirty billions. Ten years later, according to the census, it had sixfolded, rising to forty-three billions.[361:1] From the point of view of One "sitting over against the treasury" it is not likely that any subsequent period has equaled in its gifts that early day when in New England the people "were wont to build a fine church as soon as they had houses for themselves,"[361:2] and when the messengers went from cabin to cabin to gather the gifts of "the college corn." * * * * * The greatest addition to the forces of the church in the period since the war has come from deploying into the field hitherto unused resources of personal service. The methods under which the personal activity of private Christians has formerly been organized for service have increased and multiplied, and old agencies have taken on new forms. The earliest and to this day the most extensive of the organizations for utilizing the non-professional ministry in systematic religious labors is the Sunday-school. The considerable development of this instrumentality begins to be recognized after the Second Awakening in the early years of the present century. The prevailing characteristic of the American Sunday-school as distinguished from its British congener is that it is commonly a part of the equipment of the local church for the instruction of its own children, and incidentally one of the most important resources for its attractive work toward those that are without. But it is also recognized as one of the most flexible and adaptable "arms of the service" for aggressive work, whether in great cities or on the frontier. It was about the year 1825 that this work began to be organized on a national scale. But it is since the war that it has sprung into vastly greater efficiency. The agreement upon uniform courses of biblical study, to be followed simultaneously by many millions of pupils over the entire continent, has given a unity and coherence before unknown to the Sunday-school system; and it has resulted in extraordinary enterprise and activity on the part of competent editors and publishers to provide apparatus for the thorough study of the text, which bids fair in time to take away the reproach of the term "Sunday-schoolish" as applied to superficial, ignorant, or merely sentimental expositions of the Scriptures. The work of the "Sunday-school Times," in bringing within the reach of teachers all over
