The uses of snow, from
its non-conducting qualities, whether as appreciated by the Esquimaux
as a material for huts, or by the agriculturists of our own climate as
sheltering the seed, are too well known to require any particular
remarks. Strange as it may appear, the proximate cause of the
formation of snow is not yet fully agreed upon by the learned.
The connection between Sound and the atmosphere is an important one.
The air is a conductor of sound, and in some conditions one of the
best. A bell rung in an exhausted receiver gives no sound. In the
Arctic regions ordinary conversations have been distinctly heard for
the distance of a mile and a half.
All that we have thus far said in this article bears directly, in some
form or other, on another of the great features of Meteorology, one of
its great objects, and an unceasing topic,--namely, Climate.
The term Climate, in its general sense, indicates the changes and
condition of the atmosphere, such as we have been considering. It has
something to do with all of them; it is not entirely controlled by
any. Thus, places having the same mean annual temperature often differ
materially in climate.
