If all goes well. the large balloon
now building in Berlin will carry hNe
aeronauts aloft about the middle OF
JuIv. The enterprise has only one
purpose. That is TO see how long a
balloon NAV be maintained in midair,

is to be twice the size OF that In WHICH

davs. The intention is not TO return To
terra firma until the loss of gas or pal

are large factors in the variation or

have controlling effect upon the
buovancy of a balloon. The journey
must end when eAher gas or sand bal

long maintained that it is perfectly

many days. Int the feat has never yet
