Here and there in western Uganda far enough away from the death carrier's haunts to be free from the fly's visits are charnel houses whose dark walls shut off from view the tragic scenes produced by this curse to human beings. They are the detention camps where the "suspects" are herded after being brought in droves, sometimes at the bayonet's point, where they may be obstinate, to be placed where they cannot infect others. Before being placed in these thatched sheds, the surgeon's needle pierces each and fills the test tube with blood on which the lens of the microscope must pass judgment. If even a single parasite is detected the negro is condemned to confinement for life. He can go outside if able, walk or sit as he wishes. But there is a dead line where are posted black men in khaki and puttees, Uganda native guards, drilled to handle the rifle. If one of these prisoners for disease in his frenzy attempts to pass between those living statues he is seized and forced back. If he should get outside, the blacks obey their orders, but this death is a mercy if the victim had the intelligence to know it. Thus the spread of the disease has been checked, at least in Uganda,—though, nevertheless, thousands of lives have been lost,by separating the infected from the healthful. All the blacks have been taken

away from the swamp huts where the winged death might reach them and shelter given them on high and dry ground where the fly is unknown.

The captives in the detention camp, the monkey huts, the rat cages, the dog houses, provide means of studying sleeping sickness by which many of the facts known of its curse to human beings and animals have been revealed. Risking their lives the members of the fly expeditions search swamp and water shore where the rank tropical vegetation shelters their prey. Provided with long handled nets, as a tsetse fly takes wing, the net is dropped over it and given a twist. If wanted dead, it is picked out with the gloved fingers and the head put into a bottle of poison, the fly put into a covered tin box for laboratory work. But the alert negro is quick enough to catch them alive in the bush, sometimes without a net, using one finger and the thumb to grasp the wings. These fly boys are at each detention camp and also wear the khaki and puttees, but go after the winged death carrier with faces and hands bare, laughing and jumping as if having a frolic. They know the habits of the fly as the American boy knows the

In this way collections of biting flies are procured from all parts of Uganda. As each package comes in, it is examined for tsetse flies. If the parcel contains man killers, a red disk is stuck on a large map over the locality from which the flies have been sent. If, on the other hand, no tsetse Aies were found, a blue disc is fixed over the spot. In the same way and at the same time a second map is pre
