May we make a suggestion ?

labour, &c., should write to us with particulars of their
boiler plant. We will tell you exactly by how much you
can increase your steam output and reduce your operating costs.

veyors, will pay for themselves in a few months of service, and
your steam troubles will be permanently ended. Cheap steam
with unsaleable fuels immediately secured by “ Bennis ” Stokers.
We have designed a special type of hand-fired furnace for use in
Collieries. Write and ask us to tell you about it. If you don’t
find the slight trouble involved well worth the taking, your
experience will be unique.

Just 70,000 times has this lamp proved
that it gives a better light than an
electric lamp. Of course, it is the

HAILWOOD



TUBE OIL LAMP.

And it has attained this success because it has
shown these advantages.

A greater alLround candle power than an electric
lamp.

A clearer, whiter light, and one not easily extin=
guished.

A greater candle power and a greater element of
safety than any other flame safety lamp.

Greater gas=detecting properties, and it is 50 °/o
cheaper than an electric lamp.

You will be interested in the numerous compli=
ments miners have paid the Hailwood—you will
be interested in knowing the economies it can
effect in your mine.
