Transcriber’s Notes:
The cover image was created by the transcriber, and is in the public domain.
The illustrations have been moved so that they do not break up paragraphs and so that they are next to the text they illustrate.
Typographical errors have been silently corrected but other variations in spelling and punctuation remain unaltered.
Fractions have been changed from “d/d” format to single character fractions, e.g. 1/2 --> ½. However, unusual fractions cannot be converted and are left unchanged. If the unusual fraction occurs inside a table, then all fractions in that table retain the original format, for consistent appearance.

[2]The ENGINEERING EXPERIMENT STATION of the State College of Washingtonwas established on the authority of the act passed by the firstLegislature of the State of Washington, March 28th, 1890, whichestablished a “State Agricultural College and School of Science”,and instructed its commission “to further the application of theprinciples of physical science to industrial pursuits.” The spiritof this act has been followed out for many years by the EngineeringStaff, which has carried on experimental investigations and publishedthe results in the form of bulletins. The first adoption of a definiteprogram in Engineering research, with an appropriation for itsmaintenance, was made by the Board of Regents, June 21st, 1911. Thiswas followed by later appropriations. In April, 1919, this departmentwas officially designated, Engineering Experiment Station.
The scope of the Engineering Experiment Station covers research inengineering problems of general interest to the citizens of the Stateof Washington. The work of the station is made available to the publicthrough technical reports, popular bulletins, and public service. Thelast named includes tests and analyses of coal, tests and analyses ofroad materials, testing of commercial steam pipe coverings, calibrationof electrical instruments, testing of strength of materials, efficiencystudies in power plants, testing of hydraulic machinery, testing ofsmall engines and motors, consultation with regard to theory and designof experimental apparatus, preliminary advice to inventors, etc.
Requests for copies of the engineering bulletins and inquiries forinformation on engineering and industrial problems should be addressedto Director, The Engineering Experiment Station, State College ofWash
