These results show an
working efficiency of
industries, and in the case of collieries
502. We are able to reorganise a
boiler-plant to run on 70—752
efficiency under average condi-
tions, representing a saving on
colliery boiler-plants of — say 302.

We shill be glad to explain our
proposition personally or by letter,
and we are prepared to visit your
Colliery free of charge and give you
our opinion of the working of your
boiler-plant.

To SAFETY FIRSTERS.

A. MERRY - XMAS to the 2,000 Milling Finns who have allowed me
the privilege of devising and supplying things to help them in their task of
getting Profit with FULLEST Safety at their shaft pits.

Also to the thousands of shaftmen who use the Hanley Safety Rigs.
Mind, I recognise that using a Rig is sometimes awkward, and never pleasant
except at the danger moment. Still, a Hanley Rig is the only proper
form of real sympathy I could give my own shaftmen, and its usage at risky
jobs is a proof that you Value your Life and your duty to the firm.
Tolerate its use—it’s your life that is at stake.

To those who have not adopted HANLEY’S SAFETY RIGS I would
say, DO SO NOW, as, in my little time to spare, I want to persuade firms
out of the habit of using that most Dangerous, Life- and Profit-wasting tool
the fatal Unguarded Cage and to use Exactly Safe Cages, fitted with
HANLEY’S CAGE ARRESTERS.
