the new phenomena resulting from
a study of the geography of the air,
stimulated by aerial travel, according
to a bulletin of the National Geo

'Whiie the chemistry and physics
of the atmosphere are understood. the
geography of the air is still practical

in communication to the society.
Great Rivers of Air.

may not see them, there are mighty

There are vast calm areas and stag

faT-stretching heights, which, too. must
be explored, not by plane and dirigibie,
but by the sounding balloon of the
aerOgrapher.
"One might say offhand that there
could be no geography of the air; for
there are no continents, oceans or
visible geographical features in this
inverted bowl which we will call the
Sky. Do we not look clean through
the atmosphere up into the heavens
and, except for passing clouds, do we
not know that there is nothing to be
seen? rE

atmosphere. But the density decreases
with elevation and when the aviator
reaches an elevation of 10000 meters
he is in Q medium which is only about
one-third as dense as at the ground.
There are no clouds above this level.
"The greatest discovery yet made
in exploring the air is that the at

up to 10000 meters, in which there
is a steady fall of temperature with
elevation. This is called the tropo-
sphere. Above this there is no fall
and up to 10000 meters a slight rise.
The upper layer is known as the
StratOsphere.

to going 400 miles in three days, or
twice the distance from Labrador to
Ireland. The highest speed of the wind

about fifteen minutes the rate was
