Excerpt from Ground Waters and Irrigation Enterprises in the Foothill Belt, Southern California Obviously a resource which has become so important to the con tinned welfare of so rich a district is worthy of careful study. Such a study is now under way, and its results are being made known through a number of water-supply papers that are being issued by the United States Geological Survey. The earliest of these to be prepared for distribution were a series of three (nos 137, 138, and 139) relating to the coastal plain which lies between the Coast Range and the Pacific Ocean. These papers did not embody close geologic determinations, but were rather records of the developments of underground waters which had taken place at the time of their issue, with some discussion of the effects of those developments in the region treated in them.
