results seem to
show he can be, will be a wonderful factor in developing not only mining
properties where a preponderance of water is the trouble, but also
in providing an automatic, and therefore extremely cheap, mode of
water-raising and supply, which in simplicity is thus far unexampled.
Atmospheric pressure alone is relied on. The well-known process of the
syphon is the basis, but with this essential difference, that a
large proportion of the water drawn up to the apex of the syphon is
super-elevated to heights regulated by the fall obtained in the outlet
leg. This elevation can be repeated almost indefinitely by returning the
waste water to the reservoirs.

The Lemichel Syphon is a wonderful, yet most simple application of
natural force. The inlet leg of the syphon is larger in diameter than
the outlet leg, and is provided at the bottom with a valve or "clack."
The outlet leg has a tap at its base. At the apex are two chambers, with
an intermediary valve, regulated by a counterpoise weighted lever. The
first chamber has also a vertical valve and pipe.

When the tap of the outlet leg is turned, the water flows as in an
ordinary syphon, but owing to the rapid automatic opening and shutting
of the valve in the first chamber about 45 per cent of the water is
diverted, and may be raised to a height of many feet above the top of
the syphon.

It need not be impressed on practical men that if this invention will
perform anything like what is claimed for it, its value can hardly be
calculated. After a careful inspection of the appliance in operation, I
believe it will do all that is stated.

Another invention is combined with this which, by a very small
expenditure of fuel, will enable the first point of atmospheric
pressure to be attained. In this way the unwatering of mines may be very
inexpensively effected, or water for irrigation purposes may be raised
from an almost level stream.

The Griffin Mill is a centrifugal motion crusher with one roller only,
which, by an ingenious application of motive force, revolves in an
opposite direction to its initial momentum, and which evolves a force of
6000 lb. against the tire, which is only 30 inches in diameter. For hard
quartz the size should be increased by at least 6 inches. It is claimed
for this mill that it will pulverise to a gauge of 900 holes to the
square inch from 1 1/2 to 2 1/2 tons per hour, or, say roughly, 150 tons
per week.
