of possible sunshine is 6l,s per cent.
In this city We have fewer clear days

Surgeon Vollum of Fort Douglas, as
early as 1884, wrote that the climate of
Utah rs agreeable most of the year
round, excepting for month or two in
the winter The temperature IN win
ter seldom drops TO zero, and only two
observations below that point have
been taken since the post was establish
ed. The spring begins about the middle
OF March, and II Is a splendid season
The atmosphere becomes as clear as a

THE LOCAL SHOWER.
When storm originates In Salt Lake
valley. thore will be first of all a layer
OF warm air lying next TO the earth and
the lake. This air is becoming heated
ana somewhat saturated with moisture.
As q layer, or stratum, II will lie still
until some disturbances wind from
without the sound Of artillery, thunder.
etc.-dlsturbs the equilibrium The
warm air begins to rise, making the air
light over the valley, because of the
inward air movement. which is indi-
Gated by falling barometer. This air

because the air has become heavier by
losing its moisture and by becoming
cooled.
THE LARGER STORMS.
Our larger storms, like all other
storms, says Nh. Hyatt of the weather
bureau. are preceded by falling bar

indicating an air pressure of about l2
pounds. At sea level the barometer Is
normal at 30 inches, indicating an air
pressure of 10 pounds to tho square
