Twenty-first Biennial Reiport 43 habits as natural and permanent collections of surface water are more often selected for breeding ^reas. The larvae of anopheles will thrive best in natural collections of water, such as, slowly running streams, edges of shallow ponds, barrow pits, and seepage areas. Permanent water collections of this nature are common to rural and not to urban districts. The density of anopheles may be said to be in direct proportion to the opportunities offered for propagation. That malaria is essentially a rural disease is demonstrated by its disappearance from areas where the land has been drained and brought under cultivation. Since the reduction in the density of malarial mosquitoes is in direct ratio to the reduction in collections of surface water in which the mosquitoes may breed, the control of the disease through the application of anti-mosquito measures in the aquatic stage is biological in scope. Method Used in Determining Prevalence and Geographic Distribution On completion of the organization of the departments, the health officers seek to outline or determine the areas of concentration of the disease in their respective counties, and, in view of the fact that malaria is essentially a rural disease, control measures are confined principally to the rural section and small villages of the county. The first step of the departments has been to gather data as to the apparent prevalence of the disease in the county by the examination of school children between the ages of 2 and 12 for enlarged spleens, the taking of history indices as to positive or negative malaria, the establishing of blood indices and the securing of mortality statistics from the State Board of Health, From the data elicited during this preliminary survey, the health officer obtains a fairly accurate idea as to the prevalence and distribution of the disease in his respective county. From such records it is naturally shown that certain foci of infection exist in the county and ai'e the only areas requiring immediate control measures. Having established the area or areas where the disease is most prevalent, the department prepares a survey, or spot map, showing each home thereon in relation to permanent collections of water, with special reference to those streams breeding malaria mosquitoes. In areas where anti-mosquito measures are considered feasible, all the collections of water are indicated on the survey map and character indicated as to whether permanent or temporary. The density of mosquitoes in relation to occupied houses is a feature, also of the department. From the data elicited during this survey the health officer is in a position to determine the most feasible and economical measures of control which in the tidewater section consists of a combination of all measures at our command. Examination of Children for Splenomylogy In order to elicit the smaller degree of enlargement and the better to determine the exact degree of enlargement in children, it is necessary to place the child in a recumbent position with the thighs and legs flexed. The examiner sits at the right side of the child with the head of the latter on the examiner's left. The child's clothing or belt is loosened so that the hand of the examiner can be freely placed upon the bare skin, below and above the costal margin on the left side of the abdomen. First the region between the costal margin and the umbilicus and between the umbilicus and pelvis is palpated for the detection of spleenic
