Coal Saving

For Collieries.

Scientific Service.

We offer you scientific service for coal
saving in your boiler-house, and are
able to save 20—40 % of the coal bill of
average Colliery Steam Boiler Plants.

We have been engaged continuously
in this business for 10 years, we
have our own staff of Chemists and
Engineers, and we carry out ourselves
all the work necessary in connection
with the reorganisation of existing
boiler plants.

We are prepared to undertake this
work for you for (1) a fixed fee, (2) a
percentage of the profits for twelve
months only, (3) a percentage of the
profits to be agreed upon on the
understanding that we provide all
the Capital for the reorganisation, you
undertaking no financial responsibility
whatever.

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.
