The smaller balloon will be 40 feet in

pounds of 40 thread cotton cord and E
pounds of Italian hemp. 1t will be at
tached to the concentrating rings of the
large balloon, and will be used as may be
required to test the upper currents or as
sist in feeding the large balloon.
The balloons will be coated with var
nish made of boiled linseed oil, beeswax
and benzine, and Of these ingredients 1000
gallons will be used.
The capacity Of the great balloon will
be 800, 900 cubic feet of gas, but it will be
inflated with but 100000 cubic feet,
which, at the height of one mile and three
quarters, will expand sufficient to fill the
balloon. The lifting power of illuminat-
ing gas is about 80 lbs. to the 1000 feet, so
that the balloon will have lifting capacity
of II, 600 lbs. The pressure will be q lbs.
to the square inch.
TIE weight may be summed up as fol
lows.
