under the influence of high area, with
its center of maximum pressure in Dakota,
Light SHOWS in Colorado and the Lake Region
elsewhere generally fair weather.
Facts to be Remembered-1. If all parts of the
atmosphere had the same temperature and the
same hygrometric state, then all the forces OF
/ gravity and of pressure which act upon any oil
| all parts of it would be everywhere the same
| The entire atmosphere would assume the state
| of static equilibrium and forever remain al
rest.
| 2. Our atmosphere has not everywhere the
same specific gravity and is not homogeneous
On the contrary, it is an exceedingly rare and
elastic body, extending with diminishing
density to an unknown distance into space
| and pressing upon the earth with forct
equivalent to the pressure of homogeneous
atmosphere Ave and one-half miles high.
3. The atmosphere is not at rest, but con
stantly in motion. AS some parts of the eartl
are much warmer than others, and air ex
pands and becomes rare as its temperature in
creascs, its specific gravity is not the same il
all parts of the earth, and therefore the equi
librium is destroyed and system of winds i
produced.
