under the level OF other clouds, and barring
heaven like silken banner with their snowy
stripes and ribbons OF silver.
Other clouds, being less prominently de-
fined, receive their names in proportion as
they are subdivisions Of the leading clouds
For instance, there IS an intermediary cloud
called cumulo-cirTo-stratus "Oh, my"

led Latin, something like the following viii
fash through the mind "Cumulo-a heap;
cirroa curl, stratus-a coverlet; a curly, COW
erlet heap. 1t is called that because it COM
bines the peculiari.ies of all three OF the lead
ing clouds. Those who have no affection for
long Latin names can call 10 the nimbus cloud,
which is shorter or black rain cloud. which is
English. 1t Is dense, continuous, horizontal
black stratum, with fringed edges, a cap of
cirrus and cumulus below, and Is almost inva-
riably accompanied by thunder.
Tie vane cloud is long, thin horizontal
cloud, with bent or undulated edges, and is
called cirro-stratus Il often resembles shoals
Of fish, or has barred appearance, at which
time the sky is said to be mackerel-backed.
II is that fimy veil through which the sun
and moon shine family. The twain cloud is
called the cumulo-stratus, because it takes the
peculiarities Of both. 1t resembles thick
stemmed fungus, with fat anvil-shaped top.

The clouds Of Magellan are the large, lumi'

They resemble rags torn from the milky way
and consist, as Herschel says, Of swarms OF
stars In the same regions there are irregu
lar patches Of black clouds called coal sacks
due to the fact that the sky is to great ex

Clouds moderate the suns rays during the
day and the heat Of the earth during the
night. They are the sources of the moisture
which the earth requires, and their lowel
