would automatically assist the top tank, for nominally
they will keep the top tank exactly full, and will then stop of
themselves. The tower, as we have indicated, is not yet completed, and
the pumping engines are consequently doing all the work of the lifts. The
ascent and descent of the cages is effected by the attendant who
accompanies the passengers, by means of a rope arrangement.

Each cage or room is intended ordinarily to take a maximum freight of 100
passengers, calculated at about 15,000 lb. The hydraulic ram weighs about
11,000 lb., the iron frame and cross of the cage about 6,500 lb., and the
cage itself about 13,200 lb., the total being about 30,700 lb. The mass
in motion when a cage is fully loaded is estimated at 63,000 lb. dead
weight. The journey of elevation will ordinarily be made within one
minute, but in the experimental trials which have been made the full
journey has actually been accomplished in 32 seconds. In the Board of
Trade tests under General Hutchinson, weights to the extent of 15,000 lb.
were variously shifted, and in certain cases concentrated in trying
localities, but the cage stood the trials without any appreciable change
of form, and in neither the cage nor the chains were any objectionable
features developed. The three lifts can be worked singly or combined, so
that the accommodation is always ready for from 100 to 300 persons.
Further railway connections between the Mersey Subaqueous Railway and the
surrounding land lines than those which yet exist are in contemplation.

All the booking-halls, waiting-rooms, etc., etc., in connection with the
four stations have been laid with Lowe's patent wood-block flooring. The
blocks are only 1-1/2 inches thick, but, being made of hard wood and
securely fastened to the concrete bed with Lowe's patent preservative
composition, they cannot become loose, and will wear for a long series of
years, until, in fact, the wood is made too thin by incessant traffic.

The engineer, Mr. Fox, and the architect, Mr. Grayson, are much pleased
with the work, especially as it is so noiseless and warm to the feet.
These floors ought to be adopted more frequently by railway companies in
connection with their station buildings, as "dry rot" and "dampness" are
effectually prevented, and a durable and noiseless floor secured.
