Coal Saving

For Collieries.

The Boiler House.

In the average Colliery 7 % of the
coal raised is used in the boiler
house and is not available for
sale.

We are able to save 20—40%
of this large amount of coal
because the average colliery
boiler plant is out-of-date and
only running on an efficiency
of 50%.

proposition personally or by letter,
and are prepared to visit • your
