MODERN STEAMER.

bay and back from New York last
week. The new steamer is the prop
erty of the Pacific Mail Steamship
Company. The City Of Picking is in
tended to run from San Francisco 70
Yokohama, carrying principally
freight and steerage passengers. Hence
provision is made for but a limited
number of firSt-clasS passengers, in
comparison with the great size of the
vessel; but the accommodations for
storage passengers are probably supe-
rior to those of any ship that floats.
The whole lower deck can be devoted
TO this purpose, being entirely clear:
and the arrangements for Lighting and
ventila,ing this deck seem to be very
efficient. The main deck is equally
clear, and will afford a delightful
promenade 10 a full complement of
The City of Picking is i20
fee; long, has a beam of AZ. feet, a
depth hold OF SIS feet. and can carry a
cargo weighing nearly 5000 tons. The
engines have four cylinders, working
on the compound system: that is TO
say. the steam from the boilers passes
into two high-pressure cylinders. each
81 inches i'll diameter. and after NOV
ing the pis.ons in these cylinders is ex-
hausted mo u reservoir, from which it
passes into thetwo low-preSsure cylin-
ders. each IS inches in diameter, and
moves their pistons. The length Of
stroke of all the cylinders is "a inches.
There are ten bci!ers furnishing steam
to the engines. each boiler being 10.
feet in diameter and Ii feet long. The
propeller, which is male in accordance
with Hirsch's patent, is Is feet in di-
ameter. and has a mean pitch
of so feet. In other words. if
this propeller We're moving III an
unyielding medium, it would advance
80 feet in the direction oflhe axis of the
ship at each revolution Of the engines.
As, however, the water i'll which the
propeller works. does not enable the
full efficiency to be realized. a deiuc-
ton must be made on this count

the helm, were carried on by the mus
cular exertions of the crew. All this
is changed in modern steam vessels,
and the arrangements OF the City oil
Picking in this respect are very COM
plete. Four pair of engines fitted
with hosting gear, on the main deck,
are used for moving the cargo, and by
carrying the halyards and braces
around the drum of a windlass, the
sails can be raised or lowered
and the yards trimmed by
steam. An auxiliary boiler OF
the berth deck furnishes steam tc
these engines, whose services are mos
required when the fires are haulcG
from the main boilers. \ pair of en-
Gines on the berth deck gives motor

of navigation and discipline, into til,
hands of the engineer.

implies that the evidence before the
