In organizing the expedition.
An Enolishman BY the name OF Smith, one Of the
inventors Of the screw.propeller, has recently
adopted al arrangement whereby the instrument
OF propulsion is thoroughly protected: he places
the screw-propeller In tunnel.
An EnRlishman by the name OF Ewbank, IN
eminent hydraulic engineer who passed the latter
portion OF his lie In this Republic demonstrated
tnat the exhaust steam from engine cylinders
could be made tt yield much Of its potential en-.
ergy beneath otaer pistons connected with the
same SHAFT. That's to say, he condensed the ex.
haust steam IN those other cylinders-hs
utilized the atmospheric pressure-and OBJ
tanned twenty-five per cent more power
from q given quantity OF steam than can
now be obtained with he best type Of compound
engine the motor nearest to perfection. HM
engine required more space than the compound,
but less than the old style side lever engine. On
an Arctic exploring expedition each grain Of fuel
becomes more valuable than gold.
