Time passes, and the rainy season comes. Perhaps the huts become damp and even mouldy in places, and gradually, as the ants continue their ravages, the walls crack and other difficulties arise. He is forced to be continually on his guard to protect himself. Mosquitoes enter, and he is incapacitated for work, by fever and other sickness. His health becomes undermined and his appetite gives way. The coarse food of the natives, if he has been using it, becomes distasteful and hurtful. Perhaps, if there is no way out of the difficulty, his life pays the penalty and his work on earth for God and the natives is stopped. This is no fancy picture. It has been repeated over and over again in this great "White Man's Graveyard." Suppose, however, that by taking plenty of quinine and having considerable vitality to start with, he survives and continues successfully to combat disease; he soon finds that he must build a separate hut in which to meet the natives, or his house will be overrun with vermin and he cannot live in it. His hut, too, soon becomes a hiding place for snakes, rats, and lizards. He may pick up a piece of furniture and find a cobra lying beneath it, or go into the little kitchen and find a deadly puff adder beneath the cooking kettle. Even if he has in building kept as near to the natives as possible, they are in no haste to get rid of their filth and improve their manner of living. They have not yet seen the advantages of exerting themselves to that extent, unless they are members of the mission family and compelled to wash. Even then they may have conscientious scruples in reference to the matter, as one of our best boys at Matopo did. He was frequently remonstrated with for not keeping his clothing clean. He said that clean clothing made him feel proud. Again, the missionary soon sees that his hut is going to pieces, and he must go over the laborious task every two or three years of building another, and at the same time constantly fight the ants, so that his life is one of long struggle with disease, pests, and building. When and how is he to give the Gospel? He concludes that he must make brick, build a house, and put on an iron roof, that it may be better protected from the mosquitoes and furnish good rain water. He makes a tank, so that he may have good drinking water instead of the muddy, disease-laden stuff which comes from the river. It will make more work for a time, but when completed he sees some result of his labor.
