d, especially towards
morning, when the mercury will frequently drop below zero. Owing to
the absence of moisture the cold is not more noticeable here with the
mercury at zero than when 15 deg. or 20 deg. above in damp localities
farther east.

"In summer when the sun shining through the clear, dry atmosphere is
so hot, the evenings and nights are always cool and comfortable; also
in mid-day it is cool and agreeable in the shade. On account of the
absence of moisture in the air we never have any sultry or foggy
days. Through the day the mercury seldom rises higher than 90 deg. in the
shade. But the heat is not oppressive as it is at this temperature in
lower altitudes and damp climates. Such a climate cannot but be
favorable to throat and lung diseases."

On the same subject (climate), the following is by Dr. Solly, and
indeed so are all the following extracts (regarding Colorado Springs
from a medical point of view) from his pen.

"WEATHER.--WINTER.

"People (invalids) sit on porches without extra wraps; so powerful is
the sun's heat in winter that sunshades are grateful, and mid-day
picnics are taken with enjoyment and benefit. It is at this season
that the greatest improvement is noticed in the consumptives. On
turning to the tables at the end of this chapter it will be seen that
though the nights are often intensely cold, the days are seldom so.
However, until we take thermometric observations, both in the sun and
shade, and with continuous self-recording instruments, we cannot show
what is the real temperature of the hours that especially concern the
invalid. To a person unacquainted with physics or practically
unversed in climates, the cold of the winter nights may seem a
disadvantage; why this is but seldom the case is owing chiefly to the
dryness. The proportion of sunshiny days is more remarkable at this
resort throughout the year, and especially during the fall and
winter, than at any other from which reports could be obtained.

"Sleighing is seldom possible, and only for a few hours at a time in
occasional winters.

"Skating, however, is good on most days through the middle of every
winter. The frosts at night make the ice so thick and hard, that the
hours of sunlight are not long enough to melt it to any appreciable
extent, and the dry air absorbs the moisture from the melting ice so
rapidly that a smooth hard surface is usually presented for the
skaters' enjoyment.
