YEARS of STUDY
and EXPERIENCE
HAVE BROUGHT
MY SYSTEM OF
CEMENTATION
TO PERFECTION.

TO COLLIERY PROPRIETORS.

Shafts sunk, tunnels driven, and
other mining constructions carried
out in difficult and very wet ground
by the best method. Success guar-
anteed.

19 shafts in Great Britain sunk with
cementation.

Ferro-Concrete Lining a speciality.

Feeders of water in shafts or levels
effectually treated.

-------------------O--------

Because they—

Are totally enclosed and perfectly
dustproof ;

Need very little attention ;

Are of the simplest possible design,
having no superfluous parts to
increase risk of breakdown ; and
Have extremely high efficiency,
which is maintained for very
long periods under the most
unfavourable conditions.

Sizes : 5 to 1000 cu. ft. per minute.
