African children suffer a great deal from ulcers, especially on their legs. These are painful sores that break out on them, and if neglected, as they are, alas! too often, there is grave danger to the limb. Sores on the toes are common. You may see in almost any village, children running about with some of their toes half eaten away. These sores are caused by an insect--the penetrating flea or jigger which bores its way under the skin and seeks in the warm flesh a cosy place to bring forth its young. It generally selects a place under the toe nail as most suitable. When it enters first, the jigger is very small. But in a few days it grows big and may become the size of a small pea. If these pests are not promptly removed, sores break out on the toes and the toes crumble away. Now little children are unable to take them out, and if their mothers neglect to do so, the children lose their toes. I have often seen boys armed with stout thorns picking the jiggers out of one another’s feet. The process I know, from experience, is sometimes painful, for the toe under the nail is very tender, yet the black children seldom wince when the jiggers are being taken out. They are brave little things in the presence of physical pain, but they really do not feel so keenly as you children do. Their feelings are a good deal blunter than yours, and so they do not dread pain as much as you do, for they suffer less. There are some diseases found among African children that are not found among white children. Of these leprosy, the most dreadful, used long ago to afflict white children too. It is the terrible disease from which our tender-hearted Saviour freed some poor sufferers when He was on earth. Alas! one comes across it now and again among the black races of Africa. I remember once meeting a leper. He was a bright lad and was attending a class for Bible instruction. Some of the joints of his fingers were gone at the time I saw him, but he had been a leper for some years then. He told me that his father had been a leper, and that he himself began to suffer from leprosy when he was a boy of some twelve years of age. The beginning was like this. One morning he awoke and felt his hands and arms sore as if they had been burned in spots here and there during the night. So he blamed the other boys who slept in the hut for playing tricks on him with a burning stick. But they all denied it. It was the beginning of the fatal disease.
