t of snow that falls through the whole
winter is so slight that there are very few days upon which it is
seen at all. The snow when it falls rarely lies more than a day or
two, for the reasons that the dry air produces rapid evaporation and
the dry soil quick absorption, so that it disappears without evidence
of melting, and there is not the danger to the invalid of wet ground
with a bright sun overhead.

SPRING.

"The spring is undoubtedly here, as elsewhere, the least desirable
season of the year, but it compares favourably with other climates,
and there is no period of melting snow or special month to be
shunned, and an invalid can on occasion change with advantage his
location on the elevated ground of Colorado to New Mexico, for a few
weeks, guided by the weather reports.

SUMMER.

"_Temperature by Day._--In the shade the heat is seldom over 82 deg. The
air being dry, the heat is much less felt than a lower temperature in
damper climates. But there being no solar temperature observations,
the fact of the intense heat of the direct rays of the sun is not
apparent.

"_Evaporation._--This heat is, of course, to some delicate invalids,
very trying, but sun-stroke is almost unknown, and if the head is
protected harm is seldom done by exercising even during the hottest
portions of the day.

"_The temperature by night_ is almost invariably cool, as seen by the
temperature tables, and two blankets at least are grateful to sleep
under; while the mornings and evenings being cool, without dew or
dampness, give sufficient daylight hours for exercise for those who
shun the mid-day heat.

"_The rainfall_, which, with the melted snow, averages only fifteen
inches for the year, occurs almost entirely between the middle of
April and the middle of October, and falls chiefly in the three
summer months.

"_Thunderstorms_, or rather showers, occurring in the afternoons and
lasting about twenty minutes or half an hour, when much rain will
fall at that one time, are the usual form in which the bulk of the
precipitation occurs. These storms arise rapidly, are seldom preceded
by the warning sense of discomfort that is usually felt in lower
regions, and disappear as quickly, leaving a sense of refreshment
after the heat, with few and rapidly evaporating signs of moisture
upon the soil.

AUTUMN.

"The autumn is perhaps the most enjoyable season of the year, it is
very dry and warm without heat and with few storms. Altho
