steel. But in rails, in tires, in bridge rods and in boiler phlte wc ar(~, so fitr as our knowledge now goes, inelined toward soft steel. :And all the information which we lmve thus thr been al)le to accumulate in regard to these kinds of" serviee confirms our position and juslilies our eonclusi(m. And now, how can tile best results be obtained in trying to decide upon the quality of material best fitted fi)r any kind of service ? I do not see that tile steehnakers can study this question al,me, il)r after the steel leaves their hands they know very little of" its behavior. I~ doe, not come under their person:d ol)servati(m and study. lt seems to me, therefore, that tile question can only be studied by both the consumer and the producer working together. I ('annot but. regard that the interests of the consumer and the produeer in this matter are one, that neither can solve the question alone, an(1 so I ask you to work with, rather than oppose me, to utilize the information lhat is gained, so fitr as it is gained, and to constantlyhold in mind the necessary dependence of both pro(hwer and ('onsumer upon each other.

Velocity of

Light and Electricity. The probal)le identity of wave velocity ill light and electricity has been established in wmous ways. Weber and Kohlrauseh measured tile quantity: Sir William Thompson and J. Clerk Maxwell experimented upon tile electromotive tbrce; Ayrton and Perry operated upon the electrostatic e:,llacity. The extreme range of velocity in the various results was about
