e when the crops are growing; and, by the
middle of September, as a rule, the quantity has fallen off to a very
low mean, accompanied by that elastic, invigorating atmosphere for which
the State is so justly famed. This season of charming weather continues,
with little interruption, only accompanied by a gradual diminishing
scale of thermometric registration, up to the advent of winter, and even
then the moisture falling in snow is less than is generally supposed or
believed.

Since these matters are of vital character in determining the salubrity
of the climate of this State, we append the following table, both for
the purpose of comparison with other places and definiteness concerning
this.

This table gives a sweep of country from ocean to ocean, and exhibits
the rain-fall of the three climatic divisions very faithfully. The great
quantity precipitated at Astoria, in Oregon, is observed, where the
OCEANIC climate prevails, with the mountain barriers limiting its extent
inland; while, at Port Laramie, in Wyoming Territory, is an average
representation of the whole interior district possessing the dry and
elastic CONTINENTAL climate, in which lies the State of Minnesota. The
other portions of the table give a more extended view of the VARIABLE
climate, covering the eastern area as previously defined.

_Average Annual Fall of Water (rain and snow, given in inches) for a
Series of Years, as ascertained from Official Sources_.
