Mr.. Holly has written book in which he sets
forth fully his plan for supplying steam for
heating and doing all the various machine labor
of cities and villages, domestic, mercantile,
manufnct uring, etc. Uc says:
In cities or towns of from g. 900 to S, 900 nhabi
tants, where the main business portion does not
exceed onc-half mile square. one set Of boilers,
leading out in four directions. wifi do ali the work.

surface OF the earth. The iron pipes are first
covered with asbestos, aud then put In wood pipes
air between the asbestos and wood. The
outside pipe keeps all water and moisture from the
steam pipe and prevents condensation The pipes,
both wood and iron, arc put down In lengths OF
two feet, when they terminate in hollow. upright
posts. firmly secured in the earth. The upper part
Of this post is arranged rs to receive the ends of
the stcam-ptpea through atufing- boxes to allow
tue pipes to expand and contract without moving
the post. The posts also arranged 50 as to re-

TIE COMING AGE OF STEAM.
Neu York Erenina Post.
It has been somewhat more than year since
the Etvniug Post first suggested the propricty of
heating towns and cities by steam, the steam to
be furnished to househol lcrs By company,
precisely as gas is already furnished. When we
made this suggestion, and pointed out the de-
STABILITY of its adoption, we had little doubt
that in due time some company would act upon
it, but VIC had little reason to expect that prac-
ttca1 measures would follow Us speedily as they
have done.
Inc company WHICH Is 3D0ut tn undertake the
work Of supplying heat to the houses, churches,
factories, shops, and offices of Lockport, NY, has
adopted precisely the plan which the l5ueniny
Post suggested, aud the men who are engaged il
the enterprise have SO little doubt Of their sue
cess that they will begin By building an adequate
set Of works at considerable cost. There is
really no problem to be solved in the matter, no
experiment to be made. The problems were
long ago wrought ont in the heating Of large
public buildings, inns, and factories by steam,
and the new application of the principle differs
from the old one in ways which fayors its sue
cess One set Of workmeu is required for each
