Of special interest is the large mosaic showing the SanJoaquin Companys Kerckhoff dam and the power houseabove, one of the first hydroelectric undertakings to bemapped in this way. The picture is published in con-nection with the article by R. C. Starr, constructionengineer for the company, which appears on page 357of this issue. Mr. Starr gives complete data on themethods employed in making aerial surveys of hydro-electric projects and the successful results achieved. The characteristics of a drainage area vary very widelywith its elevation, exposure, timber and so forth. Allthese factors must be accurately determined before thecapacity and details of the project can be decided data can be col
