Its purpose is to aid in the industrial development of the state and nation by scientific research and by furnishing information for the solution of engineering problems. The scope of the work is twofold:-- (a) To investigate and to publish information concerning engineering problems of a more or less general nature that would be helpful in municipal, rural and industrial affairs. (b) To undertake extended research and to publish reports on engineering and scientific problems. The control of the Station is vested in a Station Staff consisting of the President of the University, the Dean of the College of Engineering as ex-officio Director, and seven members of the Faculty. The Staff determines the character of the investigations to be undertaken and supervises the work. For administrative purposes the work of the Station is organized into seven divisions-- 1. Forest Products 2. Mining and Metallurgy 3. Chemical Engineering and Industrial Chemistry 4. Civil Engineering 5. Electrical Engineering 6. Mechanical Engineering 7. Physics Standards and Tests The results of the investigations are published in the form of bulletins. Requests for copies of the bulletins and inquiries for information on engineering and industrial problems should be addressed to the Director, Engineering Experiment Station, University of Washington, Seattle.
