In mountainous countries, such as
Scotland, a fog usually forms at the
top of a hill and works downward.
The cold mountain top, cooling warm
current Of wet air, renders its moisture
Visible, and this cold fog, being of low
er temperature than the air below and
therefore heavier, drops gradually to
the valley. Colorado, however, can
show an exception to this general rule.
There in winter the frost on the low
ground is SO intense that fog often
forms in the valleys and works slowly
up the mountain side. This is known
by the Indian name of ''pogonip.''
Peru has hundreds of square miles
along it's coast of rainless country. In
this tract rain is never known to fall
from one century's end to another. Yet
the region is not entirely barren of veg
citation. Some parts of it, indeed, are
comparatively fertile. This is due to
the traordinary fogs known as "ga-
ruas." They prevail every night from
May to October after a summer that is
sultry and extend up toa level of 1 200
feet above the sea. Above 1000 feet
rain falls. .,,5.. 4- u
The "calina'' of Spain is a fog we
may be grateful that we do not have.
It is a dry, yellow mist which some
times hides the sun for days at time
over vast tracts of country and makes
the sky look as though covered with
leaden gauze. - ,. -
Another peculiar freak of weather
we must be thankful to escape is the
"williwau.'' This form of storm is
confined to that faroff island TERRA del
Fuego. The coast is indented with
deep 6ords crowned with high noun
tains. Down from their gorges drops
the "williwau." A low, hoarse mutter-
ing is heard in the distance. Sudden
~, without the least preliminary puff.
fearful blast of wind drops upon the
sea. The water is not raised into
waves, but driven into fine dust. For
tunately the shock lasts but ten or
twelve seconds, and calm follows at
once, for no vessel could stand such a
wind for even half a minute. During
the coming and going of a "williwau'
the barometer may be watched to drop
tenth Of an inch or more and rise
again at once.
Similar in name if not in nature is
the willy willy with which Kalgoor-
lie gold diggers are acquainted, to their
cost. 'Dust devils" some people call
them. Half dozen may be seen dane
| ing harmlessly along over the desert
when suddenly one will dive into the

Hannah street with dust and sand,

will steal the washing from line or
the roof from shed. In some parts Of

over the roofs of huts to save them

whirlwinds
Most people have heard of the ''fohn"
wind of Switzerland. that warm, dry
| gale which comes over the mountains
and in spring will melt two feet of
snow in a day. Its cause is most Pc
culiar. The "fohn'' comes from the
south. AS it strikes the Alps it is wet,
like most gales which have crossed the
sea. but the south face of the noun
tains receives it's rain, and as it crosses
the SUBMITS it is dry. The moving air
| current is also compressed and there
fore dynamically heated. AS it falls
into the northern valleys in cataract
of air it gains heat at the rate of half
degree for every 100 feet of descent.
It usually blows for two or three days,
causing great suffering by it's dry heat
and oppression. While it lasts the tenn
perature is about thirty degrees above
the average. The chinook" Of Brit
ish Columbia and the western side of
the United States is very similar to the
'fohn." 49,.
England has adopted the American
word 'blizzard" for gale with snow.
But the blizzard, however, must yield
to the ferocious duran" of the central
steppes of Asia and the ''purga' of
northern Siberia. To be caught in gales
such as these means death in a very
few minutes, however warmly clad, for
the very air becomes unbreathable, so
filed is it with spikes of ice drift.
"Khamsin'' is the hot wind from the
desert which blows out Of the Sahara
upon Egypt The word means fifty,
from the idea that it lasts, for fifty
days. The ''khamsin" is terribly hot
and dry and sometimes brings pesti-
lence with it.
Red snow we have all heard Of. It
is caused by microscopic infusorial
growth and only occurs in snow that
has lain unmelted for long time. In
Spitzbergen recently green snow has
been noted tinted by similar organisms.
''Gold dust snow has often been
seen, but only in spring. At one time
it was a mystery how the surface of
i new fallen snow came to be streWn
with shining yellow deposit. Now it
1 is known to be due to the pollen Of
