51 North Carolina Board of Health to the Southern Power Company which will market it for industrial or general use locally or broadspread as the demand may arise. The project is located on a twenty-three mile section of the Yadkin river, occupying an area from the dam and powerhouse site at High Rock Mountain eighteen miles east of Salisbury; along the territory of the common border of Davidson and Rowan counties, upstream, northwest, touching Davie county on two sides by branching into the South Yadkin river for eight miles. Figures given for the lake and dam are as follows: dam, 59 feet high, 1,200 feet long; lake 19,000 acres or 20.7 square miles in area, 300-mile shore line, to back water 23 miles. The mosquito surveys on this project were carried on through two seasons—1926 and 1927. The history and blood work was terminated in the first year. Work of this type on a large project is volumnous and in many respects subject to the difficulties that go with the organizing of temporary forces of limited personnel for such work. Due cognizance is taken of this and results evaluated accordingly. Malaria in the High Rock Territory History and blood indices disclose that for the period embraced by the 1926 survey in the High Rock territory, malaria as compared to districts in which the disease becomes a major problem, was not a feature of public health importance. The infections as shown by histories was 1.789f, by blood smears, 3.50%. It is well, however, for those interested in malaria and malaria control to remember that the problem is a constantly shifting and fluctuating one and that it is practically impossible to secure a picture of the disease at rest, nor is it expected that the parasitic or history indices will remain the same for long periods of time. Sectional differences, in view of the disease and toleration for it, will have influence. Also, the experience gained in one community may be entirely contradicted by that from another of similar type. Mosquitoes in the High Rock Territory The outcome of the mosquito survey in the High Rock territory amply meets any normal expectation that may have been held for it. Both Culex and Anopheles existed in proportion as they were aff'orded sanctuary and favorable conditions. Culex were generally prevalent in limited quantities throughout the territory, with exaggeration in sections when afforded fitting encouragement such as conditions of water contamination by rubbish, waste, or sewage. This was given expression in the increase in prevalence during dry seasons. Punctipennis existed in by far the greatest quantities, which marks the section as majorly Punctipennis grounds. This measures up to original appearances, that at large the section topographically was fitted best to the production of this type of mosquito. Quadrimaculatus existed in limited quantities and were fairly well distributed under general conditions throughout the territory. They appear prominently where efforts were confined to territory of the type most suited to them. This again supports original indications, that while the territory was by nature majorly of Punctipennis producing proclivities, it also would be subject to local Quadrimaculatus production.
