FIRELESS ENGINES.

Erookiyn's Prospects for Rapid Ira nsiL
The problem Tor rapid transit seems to be in the
process OF solution among our neighbors In Brook
lyn, ana, although the method OF arriving at this
desirable result which has ob aimed most favor IN
the eyes of at least one OF the principal ralrold
magnates OF our sister city mas not be the best,
1t is still worthy OF notice During the last lew
weeks experiments have been made in the neigh.
borhood Of East New yorh and on the track OF the
Atlantic Avenue Railroad Company, for the pur-
pose of testing The availability OF the invention OF
DR.. Emile Lamm, OF New Orleans and their results
have been reported as satisfactory. DR.. Lamnl's
invention consists of nrc'css steam engine,
w,ch Is intended to take the place OF the ordinary
dummy, and to do ITS work without giving any
ground for the objections usually brought against
the latter, such frightening horses or teams on
the road, and thereby causing numerous acci-
dents.
The fireiess engine is supplied with steam from
stationary boiler, and in the manner by which this
steam is supplied and preserved consists the prin-
cipal merits OF the invention. The boiler OF the
locomotive is constructed OF sheet steel, three.
eghtbs OF an ncn thick, with an air space immed-
atey supervening about one inch in depth, formed
py means OF small rings OF the best non conducting
wood attainable, over which is wrapped a hair.
cloth felting, two inches thick. Above the feltlng
there Is another air space, similar to the above,
and over all covering OF Russia iron. The pur.
pose of this covering Is to retain the heat IN the
boiler OF the locomotive, which is supplied from
the stationary boiler. The capacity OF tic boiler
Is 325 gallons, and 1t is always kept,
wien In use. about three quarters full.
Under the boiler Uf the locomotive there are usu.

pounds per square incn, ana 10 IL calculated that,
with TINS amount OF pressure to start with, the en-.

grade. OF course steep grades WIN require .
greater expenditure ol steam, and provision
Tor supplying the necessary amount Will
be necessary. The Atlantic Avenue Railroad
Company propose to nave one stationary
boiler at the corner OF Atlantic and Fatbnsh ave.
nues and another at East New YORK. so that the
dis ance between the two will lie only ABOUT four
or five miles, tnus aiording an ample margin for
extra waste OF steam, 1t Is SAID tnal the engine
