Members of the American Association of Petroleum Geologists are engaged in serving the petroleum industry; fundamentally, however, they are geologists with a broader vision than the mere economic aspect of their work. They should lend both interest and active support to geologic work that seems to fall in the realm of pure science. Matters of purely academic interest to-day may be of utmost economic importance to-morrow. Geologists of the Association have exceptional opportunities to serve the science which brings them their livelihood,--opportunities of observation in remote fields and investigation of unsolved problems. More specifically, as petroleum geologists, they must be interested in the realm of engineering, recognizing the importance of physics, chemistry, and m thematics. There are three organizations through which they can work to advance organized studies of the geologic and engineering problems of the petroleum industry, namely, the American Association of Petroleum Geologists, the National Research Council, and the American Petroleum Institute.
