locomotives after .1900, he iaciades && interesting chapter on the
early dsvelopjaeni of the stea© locomotive. Fortunately, in this
he features the Semiaolo. Because of his own eminence as a
locomotive railroad engineer * Mr. Bruce V cosaneats about the
Seminal® specifications, and how much is left to the craftsmen
and not detailed in specifications, are worth not^ta® as this
practice undoubtedly was ef general applicatiooi in the period and
relate to $119 and the Jupiter. On t&is point he says:

folloa^d for the coastruction of the boiler or Sefe the
uadiiBing of the detail parts and their asseE&ly, all of
which are apparently p
left to the attdgment and facilities
of the locoiaotiv* lwdlder. With but few exceptions, no

and cast and wrought iron were then conaaerci&Ily available,
this is not surprising* for eariy ia the industry definite
