pioneer spade work of the missionaries, digging through the barricades of language that separate the minds of men! When, then, the missionaries had books to give the people, the people had to learn to read. So the missionaries became educators, and wherever you find the church you find the school. But what is the use of educating people who do not understand how to be sanitary, who live in filth and disease and die needlessly, and how can you take away old superstitions and not put new science in their places, or deprive the people of witch doctors without offering them substitutes? So the missionaries became physicians, and one of the most beneficent enterprises that history records is medical missions. What is the use, however, of helping people to get well when their economic condition is such, their standards of life so low, that they continue to fall sick again in spite of you? So the missionaries are becoming industrial reformers, agriculturalists, chemists, physicists, engineers, rebuilding wherever they can the economic life and comfort of their people. The missionary cause itself has been compelled, whether it would or not, to grow socially-minded. As Dan Crawford says about the work in Africa: "Here, then, is Africa's challenge to its Missionaries. Will they allow a whole continent to live like beasts in such hovels, millions of negroes cribbed, cabined, and confined in dens of disease? No doubt it is our diurnal duty to preach that the soul of all improvement is the improvement of the soul. But God's equilateral triangle of body, soul, and spirit must never be ignored. Is not the body wholly _ensouled_, and is not the soul wholly _embodied_? . . . In other words, in Africa the only true fulfilling of your heavenly calling is the doing of earthly things in a heavenly manner." [2]
