no doubt hat a drome will increase
its speed in the rarer ar high above

win says that it is absurd to judge he
speed OF a flying machine by its per
torrance at a low elevation. He
says that the resistance of the air lie
~creases as the air grows thinner ard
at the same time the power which
moves the machine has tho same force.
He asserts that when the machine
rises to a height OF $1,000 feet Il gets
into air which is only half as dense
as the air at the ground. According
to him, the propeller then meets With
only half the resistance, but it can
go twice as fast, and it therefore has
the same pushing force as at the
ground. At the same time the aero
? drOme itself meets only half the re
l %sistance and therefore it goes twice
! as fast. He describes the speed OF
the drome near the groun1 as Ike

l says all that is necessary for a nigh

( ment, such as we have on our auto
mobiles. You change your gear as
] you rise, just as you do with your
c car when you go up Hill. In this way

Now. if Mr.. Baldwin's calculation.
should prove true in actual flying, tn
