48 North Carolina Board of Health first year's work showed a sparsity not reconcilable with malaria conditions. However, the second year's work brought out evidence of a density compatible with conditions. Culex mosquitoes were present in varying quantities according to fluctuation of favorable breeding locations. Since this variety is a contaminated water breeder, its prevalence is effected to a great extent locally by man-created conditions. The significant thing about this situation is its contradiction of the generally prevalent opinion regarding the presence of mosquitoes, especially the malaria carriers, in mountainous sections. Norwood Project The Norwood project of the Carolina Power and Light Company is located on the Yadkin river and extends from the dam adjacent to the town of Norwood upstream to the Uharie river, a distance of approximately twenty miles comprising a lake of 5,294 acres. It is one of the major developments of the State. Mosquito surveys were made on this project through one season with a showing of what may be termed a normal mosquito production according to expectation. This may seem to be a somewhat indefinite disclosure, however, in the absence of any standard of measurement or comparison this with the further qualification that may be gotten from survey records is the only depictatory means of setting forth the condition. Both Culex and Anopheline mosquitoes were prevalent about the territory, the latter in all three species—Quadrimaculatus, Crucians, and Punctipennis. Anopheles Crucians were present only in limited quantities. Anopheles Punctipennis was the prevailing type which is characteristic of positively deliiv-itous country with active streams. There was, however, sufficient departure from this condition to produce in appreciable quantities Anopheles Quadrimaculatus, the malaria carrier of primary sanitary importance. This was sufficiently pronounced to spread malaria in one section to epidemical proportions. A significance of the presence of this type of mosquito is that it demonstrates their ever-readiness to utilize the smallest turn of favorability and what may be expected of them if undeterred when thousands of acres of favorable breeding water is left at their disposal. Resurveys While intensive studies on impounded waters were discontinued after the basins of the lakes were flooded, attention to them was not discontinued. Follow-up surveys were made at intervals in order to check up on developments and to discover any undesirable trend that it might be headed off early. This is especially valuable in the interests of health and also to the promoting interests. It is very difficult to estimate what turn of affair may develop in a new pond before it has bedded down and reached stable conditions. Here these resurveys are especially valuable in serving the purpose of health work. These surveys vary from those of the studies in that they are a specific application to a given condition such as sampling or trouble spotting. Surveys of Towns Surveys of towns may follow various courses according to their demands in clearing up mosquitoes and mosquito borne diseases. They often may go 'on for years tolerating a mosquito condition until attention is focused
