OPENING OF THE NEW WORKSHOP OF THE STEVENS INSTITUTE OF TECHNOLOGY.
In our SUPPLEMENT No. 283 we gave reports of some of the addresses of
the distinguished speakers, and we now present the remarks of Prof.
Raymond and Horatio Allen, Esq.:
SPEECH OF PROF. R. W. RAYMOND.
A few years ago, at one of the meetings of our Society of Civil
Engineers we spent a day or so in discussing the proper mode of
educating young men so as to fit them for that profession. It is a
question that is reopened for us as soon as we arrive at the age when
we begin to consider what career to lay out for our sons.
