Coal Saving

For Collieries.

Payment by Results.

As a result of 10 years experience
as specialists in Economical Steam
Generation, we are able to save
20—40 Z of the Coal Bill of average
Colliery Steam Boiler Plants.

Further, we are prepared to take in
hand the reorganisation of your Boiler
Plant and supply all Machinery and
appliances that may be required,
together with brickwork and founda-
tions entirely at our own expense.
and we are willing to be paid by a
proportion of the savings for a fixed
period to be agreed upon.

We may say that we are only in a
-position to make this offer because
of our accumulated experience of
hundreds of Boiler • Plants.

We shall be glad to explain our
proposition personally or by letter,
-and are prepared to visit your
Colliery free of charge and give
you our opinion of the working
of your boiler-plant.
