217 Robert E. Kuntz Camel Drivers, Preparing to Leave Ta'izz, Feed Their Grumpy Beasts by Hand Yemen depends upon the camel to carry many of its burdens. Before a caravan sets out on a long journey, drivers stuff bundles of fodder into the mouths of reluctant beasts. They say that camels do not eat enough to endure a prolonged journey unless they are hand-fed (page 220). to work for the United States Army and Navy during and following the war, and he understood both the Yemenis and what we needed to know. All comers were given a complete medical examination and medicine when necessary. To our amazement, even a few women were bold enough to venture upstairs for treatment. Snails Hunted as Disease Carriers In our third-floor laboratory we investi gated the biological background of human diseases in Yemen (page 234). Dr. Robert E. Kuntz searched for internal parasites of dozens of animals in the Ta'izz area and specialized in a study of the fresh water snails which might be host to the dread fluke disease, bilharziasis, or schisto somiasis. This debilitating and often fatal disease, a scourge chiefly in the Tropics, is common in the middle altitudes of Yemen. With his considerable background in the study of bilharziasis, Dr. Kuntz easily found likely-looking snails in the public baths, quickly determined that they were actually infected, and set off to study the incidence of the disease in the city. To eliminate new cases, he simply suggested more frequent changing of the water in public baths to flush away the snails. In another corner of the room the mos quito expert, Dr. Kenneth L. Knight, raised local mosquitoes from wriggling larvae--col lected in wells, public baths, ditches, and streams-to mature, winged adults, then stuck each one on a pin for later identification. In the middle of the room I set up my old portable field laboratory and examined local rodents and small game for fleas, lice, ticks, and parasitic flies; took blood samples, and entered my observations in the log. At my side, a Yemeni boy stuffed rodents.
