generally in use on ocean vessels
throughout the world.
AS a result of the voyage Cramp en-
gineers predict a more rapid growth
of motor ship tonnage. 1t is pointed
out that, as a result Of greater econo-
mics, practically all of the motor ships
in various countries, regardless of
age, are in active use, while a large
proportion of the steamships are now
idle.
The Diesel motor still is in process
of development and is in use chiefly on
freight vessels up to II knots speed
and 1900 tons. Experiments on fast

First Large Motor Ship.
The William Penn has the distinc-
ton of being the first large American
motor ship suitable for deep-sea cargo
trade She is operated by the Barber
Steamship lines for the shipping board
and recently returned to New York.
Mr.. Metten describes her voyage as
follows:
1.-THE Penn Is 455 feet over all, with
a draft of % feet loaded, of 1876
tons lightweight carrying capacity.
She is propelled by two Cramp- Bur
meister & Vain type six-cylinder
Diesel engines, having cylinders of
29A inch diameter and 45A Inch
stroke, each engine directly connected
to a propeller through shafting, the
vessel being twin-screw. The engines
are designed to develop together 1850
Indicated horsepower when turning at
lis revolutions per minute. There are,
in addition, three auxiliary Diesel en-
gtnes, each directly connected to 65-k.

"There are several sister bulls, |
equipped with either steam turbines or
reciprocating engines, which have
been laid up for the last year due to |
their inability to run at profit, while |
the motorship William Penn mas been
able to show a fair return to the own
ers and operator during the recent |
slump in shipping.
'aThe William Penn left New York
on September 8, 1921, stopping at
Savannah to complete loading. She
then sailed to the Far East via Pana-
ma canal and Honolulu The first stop
to discharge cargo was at Yokohama.
The vessel then proceeded in success
sion to Kobe, Shanghai, Foochow,
Swallow, Hongkong and Manila At the
latter named place unloading was COM
pleted and loading again commenced
for the return voyage. Stops we're
made at Cuba, Philippine islands,
Surabaya, Singapore, Straits Settle
nents, Suez, Port Said, Marseilles,
London Rotterdam and Liverpool
From the latter place the vessel sailed
