The problem Of supplying a steam mo
tor fnI street railways. without the objec-
uunable features Of tire and smoke. seems
at length to have been solved. An ingen-
lOus inventor IN New Orleans has cOncelV-
ed the idea ~ storing steam At a higher
temperature and consequent high pressure
ia a cylindrical reservoir, made like an or
binary boiler, and "jacketed" to retard
radiation and loss of heat This reservoir
Is connected With an engine of ordinary
construction, whose motion supplies the
necessary power II has been found BY
experiment that power enough can thus
IL st"rud up 70 carry an ordinary street
car, with fun load, distance Of nine
miles The power being exhausted, the
reservoir is recharged with steam from
stationary boiler. the operation requiring
less than five minutes, and Is ready for
another trip Absolute safety is secured,
~ the pressure is constantly decreasing
from the moment the charging process
ceases and as the only care the engine
needs during its trip is the proper hand
ing If the valve which lets on and shuts
of the steam from the reservoir, no skill
ed engineer is required to drive it. The
locomotive has been practically and thor
oughly tested in New Orleans, on a street
railroad, If which General Beauregard is
president, and has given, thus far, the
most entire satisfaction.
