Entered as second-class matter September 5, 1919, at the
postoffice at Pullman, Wash., under Act of Aug. 24, 1912
The ENGINEERING EXPERIMENT STATION of the State College of Washington
was established on the authority of the act passed by the first
Legislature of the State of Washington, March 28th, 1890, which
established a “State Agricultural College and School of Science”,
and instructed its commission “=to further the application of the
principles of physical science to industrial pursuits=.” The spirit
of this act has been followed out for many years by the Engineering
Staff, which has carried on experimental investigations and published
the results in the form of bulletins. The first adoption of a definite
program in Engineering research, with an appropriation for its
maintenance, was made by the Board of Regents, June 21st, 1911. This
was followed by later appropriations. In April, 1919, this department
was officially designated, Engineering Experiment Station.
The scope of the Engineering Experiment Station covers research in
engineering problems of general interest to the citizens of the State
of Washington. The work of the station is made available to the public
through technical reports, popular bulletins, and public service. The
last named includes tests and analyses of coal, tests and analyses of
road materials, testing of commercial steam pipe coverings, calibration
of electrical instruments, testing of strength of materials, efficiency
studies in power plants, testing of hydraulic machinery, testing of
small engines and motors, consultation with regard to theory and design
of experimental apparatus, preliminary advice to inventors, etc.
Requests for copies of the engineering bulletins and inquiries for
information on engineering and industrial problems should be addressed
to Director, The Engineering Experiment Station, State College of
Washington, Pullman, Washington.
The Control of the Engineering Experiment Station is vested in the
Board of Regents of the State College of Washington.
