Coal Saving

For Collieries.

MAGGIE BROS. LTD.,

Shortage of Steam.

Many Collieries to-day are seriously
handicapped by shortage of steam, and
unable to obtain additional boilers.

Most Colliery boiler-plants are working
much below their proper evaporative
capacity because of lack of up-to-date
methods of steam generation.

We can in average cases increase the
evaporation at least 50 % per boiler.

We are prepared to undertake the
work entirely at our own expense, and
are willing to be paid only by a pro-
portion of the saving for a fixed period.
We may say that we are only in a
position to make this offer because of
many years experience.
