Coal Saving

For Collieries.

The National Interest.

It is of vital importance that coal
should be saved, because of shortage
of labour, difficulties of transport, the
needs of industry, and the necessity of
maintaining the export to our allies.

The best field for coal economy to-day,
especially in collieries, is the boiler-
house where in average cases 25-40 X
of the coal used can be saved. The
reason is that the business of scientific
methods of steam generation is that of
a Specialist.

We have been engaged solely and
continuously in this business for 10
years, and we are not amateurs who
have taken it up in the last few months.
Also we are not interested in the sale
of any plant, machinery, or appliances,
or in any other firm.

We are so sure of effecting a saving, as
a result of our unique experience, that
we are willing to carry out the work
on the principle of payment by results.

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.
