When water freezes solid in verycold weather the particles of air whichare normally held in solution by thewater, are forced out, and the mass ofice contains practically nothing butpure water in the solid state. A veryinteresting experiment was years agomade by Michael Faraday in order todemonstrate the peculiar effects whichcould be produced when such waterwas boiled. Under the conditions hesecured in the laboratory, steam was. VALVE GEAR CROSSHEAD. X. Y. C. 154 RAILWAY AND LOCOMOTIVE ENGINEERING. April, 1911. Technical Education of Railway Mr. Ogden sent us the articlewhich here follows on the technical edu-cation of railway mechanical foremen, herequested Dr. Sinclair for an expressionof opinion on the subject. At the end ofthe article we print Dr. Sinclairs letterand would invite as many of our friendswho desire to add something to the dis-cussion of this important matter, to writeto Railway and Locomotive Engineer-ing and give their views. Technical Education of Railway Me-chanical t. h. question that is vital in the operationof the locomotive department of todayand the future is, How can the foremanpromote greater shop efficiency? Inconnection with this progress and devel-opment, because of its radical characterand great extent, the development of menhas been allowed to t
