Coal Saving

For Collieries.

Our Special Proposition.

We are prepared to make a complete
scientific investigation of the working
of any Colliery boiler-plant and to
design a scheme of reorganisation to
obtain the maximum saving possible,
which in average cases will vary from
20—40 X of the coal bill.

We will then carry out the reorganisa-
tion and supply the machinery, plant,
and appliances that may be required,
together with all brickwork and foun-
dations, and lend the services of one
of our skilled engineers to work the
reorganised plant under our super-
vision until the results are obtained.
We will carry out the whole of this
work entirely at our own expense, and
are willing to be paid only by a pro-
portion of the savings for a fixed
period. At the end of this period the
reorganised plant will become the pro-
perty of the Colliery irrespective of the
savings, and no financial responsibility
whatever will be incurred except by
•ourselves.

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.
