Are giving solid satisfaction in COLLIERIES,
MINES, QUARRIES, &c., all over the World.

New Boiler=Plants.

The average nett working effi-
ciency of new Colliery boiler-plants
erected to-day is only about 60.].
The new boiler-plants designed on
scientific lines will give 75—802
efficiency, corresponding to an
annual saving of—-say 202, which
goes on for the whole life of the
plant (say 20 years).

We offer you our services as
Specialists in this business with
ten years continuous experience,
including every description of
boiler-plant in almost every
industry.

We are prepared to design for you
a plant on the most up-to-date lines
and supply all drawings, specifica-
tions, and builders’ quantities. Also
advise on the fuel to be used and
the treatment of the boiler-feed
water, and carry out all the chemical
analysis necessary. Further, we
will send you down one of our
trained engineers to instruct your
boiler-house staff in running the new
plant until the maximum efficiency
is obtained.

We shall be glad to explain our
proposition personally or by letter, and
are prepared to visit the proposed
site of any new plant free of charge.
