Wisdom
By H. G. Horton
and Frank Rigney
The cumulus is the typical summer
sky cloud form. Great masses of
beautifully shaded vapor pile up in
this sky, and its various shapes are
truly wonderful. But when the sun
has drawn up so much vapor that
these clouds can contain no more, the
cumulus becomes dark on its under
side, and precipitates rain or snow. It
is then known as a cumulo-nimbus,
some of the cumulus shape remaining
above while the nimbus form is seen
below. When fragments of cumulus
clouds are torn off by high winds,
these fragments are known as fracto-
cumulus.
Then we find the nimbus, or storm
cloud. A shapeless, dark cloud form
from which rain or snow is contin-
ually falling, it may be formed from
a cumulo-nimbus, or come up the sky
as a straight nimbus. At any rate
one has to carry an umbrella when
this cloud appears.
In the early morning of a fine fall
day we often see the stratus lifting up
from the valleys. Higher and higher
it goes, obeying the power of its mas-
ter, the sun. As it twists and rolls
upward, revealing the landscape be-
low we cannot help but think of
"When the mists have rolled in
splendor
From the beauty of the hills."
There is a possibility of the Boy
Scout writing something more than
" Rainy" in his diary—for most
storms have the story of their mak-
ing recorded to the weather-wise
cloud observer. How often we hear
old sailors start a yarn " On the 28th
of September 1899 the sky was clear
and the barometer—" And then
after five days of weather report
have their ships steaming full speed
into a hurricane to keep from drag-
ing anchor in some Harbor, Havana,
perhaps.
The rapidly increasing airplane and
dirigible routes planned call for a
much closer study of the atmosphere
than has been made hitherto. Sea-
scouts learn the air pressure by the
barometer, the humidity of the air by
the psychrometer (wet and dry bulb
thermometers') and note the cloud
forms and wind velocity also. From
these data one can get a fairly good
weather forecast. It might be a good
thing to have your troop subscribe to
the daily U. S. Weather Bulletin,
which is a very valuable chart of
weather conditions.
