Whether or not the missionaries have had training in such work in civilized countries, the exigencies of their surroundings, far from doctors and medical help, necessitate their devoting time and study to the cases continually brought before them. Many of them become quite proficient in treating diseases; and perhaps some, in time, become by practice more skilled in treating diseases of tropical climates than some physicians of temperate zones would be, who were unused to tropical diseases, even though they might display their sheep-skin to show a theoretical knowledge of the science. The safest and best course, however, would be to acquire some of the theoretical knowledge before coming to Africa, and then be ready for the practice. It is needless to state that the missionary's practice among the natives is not a lucrative one. Medicines are very expensive, and a physician must have a diploma from an English medical college before he may charge for his professional services in an English colony. Even then his heathen patients are not prepared to pay much should he feel to charge--which he generally does not. The missionary's labor is one of love, and he rejoices that he has the privilege, in a small degree, of being a follower of the Great Physician. Aid for the body of the natives is one of the best ways of reaching their hearts and souls. [Illustration: Ruth Taylor.] During the two weeks' vacation in July some of us concluded to spend the time in evangelistic work among the villages. We knew the change to outdoor life also would be beneficial to ourselves. There was one village, Kabwe, composed chiefly of Baila people, where an interest was being manifested, and several there had been attending school. This was distant about fourteen miles by wagon road, and we decided to go there, David and his wife and the dear little baby, who had come to bless their home, accompanying. Word was sent ahead that the people should erect a temporary straw hut for them, while I occupied the tent wagon. When we reached the place we found everything prepared and in readiness for us, and the people also. We received a royal welcome from all and were soon comfortably situated. There were fifty huts in this village, and every evening after the people had finished their day's work and had eaten their suppers, about fifty or sixty of them would come to us, sit around our bright log fire, and listen most attentively, while the Word was being expounded, and then quietly kneel in prayer, and mingle their voices with ours in song. In the morning again, before they went to their gardens to dig, they would assemble for services. On Sunday we gathered on the side of an ant hill, in the shade of some trees, and here a much larger number came for services. Generally during the day David would go to the surrounding villages and proclaim Christ.
