Twenty-first Biennial Reiport 53 not included in this calculation. When one takes into account the present condition of screens, and 1923 incidence of malaria, it is seen that these with poor screens had a greater incidence of malaria, 64% as compared to 47%, This is a significant difference, but is not as large as one would expect. From the available data, it is impossible to evaluate the role of screening in the reduction of malaria. One feels that the screens have been an important factor, but their value is not shown in these tables. Summary of Factors in Malaria Reduction It is probable that all the above factors have had a part in the evident reduction of malaria since 1922. Deficient rainfall has been of great importance in 1925 and 1926; the very general use of screens, and a change to a finer mesh, has undoubtedly saved many people from being bitten by mosquitoes; while the intensive quinine treatments of 1923 and succeeding years were undoubtedly greatest benefit. It seems justifiable to assume that wholesale use of quinine reduced the parasitic rate so low that the other protective factors, screens, deficient precipitation, etc., which has been partially uneffective before on account of universal prevalence, were able to make their influence felt in a lesser malaria incidence. Summary A short survey of a small area in Beaufort County showed a 11% spleen, and 1.5% blood rate, where malaria had been very prevalent only a few years before. Of the conditions apparently responsible for this decline in malaria incidence, it seemed probable that an intensive treatment campaign in 1923, with follow-up campaign in succeeding years, had reduced the parasite rate to so low a level that the other factors, screens, deficient rainfall, etc., were able to exert their influence and keep the rate low.
