Result of Moisture.

such as the evaporation of persplration,
When the relative humidity Is high. and
the temperature is also high, the indlca-
tions are that tho air is holding about
rs much heat in the form of vapor as II

Upon some days when the thermometer
scars upward people seem not to notice
the heat. 1t is because OF low humidity.
The air is free of moisture 10 the extent
that its currents pick up heat and trans

rapid. Humidity is always higher or
denser near the ground and ncar water
1t Is often the case that people who suf-

onto the housetop. The fact that high

"Tabbing' Humidity.
The local weather office obtains the
relative humidity in an interesting man
ner. which is also demonstratlve of the
foregoing. Two thermometers are SINH
building. one having thin muslin COW
ering on the bulb. which is kept wet,
the other being free and dry. Both are
whirled around at the same velocity on
so as TO be famed as by the ordinary
wind or air currents. Both will show
different readings. the wet bulb being
lower and the amount Of humidity being
shown by the difference in the records OF
the bulbs, The amount OF this differ
ence varies directly with the amount OF
moisture in the air, or which is the
same thing, with the rate of evaporation
from the wet bulb. So that when the
humidity Is high. the air can hold little
OF no more vapor and evaporation is
slow or nil.
The more moisture there is in the
atmosphere, the less rapid will be the
taking up Of more moisture by evapora-
tion. and the face of the workingman

satisfying. The specific heat OF a moist

dry air A hot-water bottle furnishes
heat longer than a bottle of hot air. II
the evaporation from ones body Is rapid,
the real air temperature will be felt less.
The moister the air. the less will be the
possible evaporation and the less the
cooling by the evaporation of perspira-
ton. The high relative humidity is the
prime factor in the death dealing hot
waves OF the east. which are climatic
abnormalities wholly unknown TO Utah.
