N. Spiass. a French inventor, Is now
building a rigid airship which although
Of a type similar to the Zeppelin differs
from It In many important points. The
Spiess ship will be built of very light and
tough wood which has been specially
treated. From tests already made tie
inventor expects to get greater stren3sn
and reduced weight by this means OF
construction as compared with the alu-
minum vessel. Six gas containers will
be fitted within this body instead OF the
seventeen used with the Zeppelin.
At the French aeronautic works OF NJ.
GODDARD q new dirigible balloon is being
built capable Of carrying a crew Of three
and one passenger. OF attaining a speed
Of forty kilometers an hour, OF remaining
in the air for a period Of ten hours and OF
