$ 100,000,000 in excess of its present value. The fairy tales of west-
ern farming, and adventures in western cities, with paper corner
lots, together with inducements held out to invest money in western
railroad bonds at the inflated usurious rates of ten per cent, for
money thus invested, when the road could not pay more than run-
ning expenses, have been the greatest injuries as to the prosperity of
New-Hampshire. There is no doubt but the lessons so dearly
bought by many persons in this State, will be of lasting benefit to
the generation to come, both to their happiness and wealth.

CLIMATE OF NEW-HAMPSHIRE.    *

Like all other New-England States, the climate of New-Hamp-
shire is exceedingly various as to heat and cold, and attended with •
sudden changes.    i

The extreme varation of temperature is from twenty to thirty de-    ’    i

grees below zero, to ninety-eight or one hundred above, but these
extremes do not often occur. The extensive ice-bergs in the north-    j

ern sea, fogether with the various currents of air cause cool breezes    ¹

to pass over the hills and through the valleys, and in the summer the
hot rays of the sun, on these cool currents of air, and upon the heavy    |

forests create a moisture which produces frequent showers. Thun-    ¹

der showers are frequent through the hottest portion of the season,
but never as violent as in the Western or Southern States, and
seldom attended with high winds. Whirlwinds and tornadoes are
very rare, yet not unknown. A whirlwind that passed over Suna-    *

pee, New London and Warner, Sept. 9, 1821, was the most severe
ever known in this section of the country. The lofty elevations in    I

various sections of the State break the clouds so that it is nearly    ‘

impossible for long sweeps of wind, as on the prairies in the West.

Summer showers are also broken by the high hills and mountains,
and move through the valleys between the mountains. Very often
