ase absent, in the other obscured, a
comparative state of lethargy or repose is prevalent, and the natural
functions of vitality are but feeble in their action, if not in some
cases, absolutely in a quiescent state; with such a state of things
existing, it is barely rational to apply stimulants, and to induce
unnatural excitement. The application of exciting and stimulating agents
at such periods, may be compared in its effects to the excitement of a
frightful dream acting on the human frame; the vital functions--not the
vitality itself--cease during sleep, and both the animal and the vegetable
should be at rest; excitement acts on both by deranging the system, at
least for a time, and since a succession of these derangements are known
to produce injurious results, we may be certain, that each seperate
instance must have an evil tendency.

In applying this practically, to the case before us, it may be
recommended, that the temperature in which Cucumbers are grown during
winter, should not fall much below 60 deg. Fahrenheit, at night; and in
the day time it should not rise above 70 deg. in dull weather, by the aid
of heat artificially applied; in clear weather, by the influence of that
glorious source of light and heat, the sun, it may be safely allowed to
rise to 80 deg., or a little higher, before air is admitted. A somewhat
higher range may be permitted, as the days lengthen, and the influence of
the sun becomes more powerful; thus at night, it should not rise over 65
deg., by day 75 deg. to 80 deg., and by sun heat to 90 deg. Thus it will
be seen, that I have recommended the regulation of the temperature of the
internal atmosphere, by that which is external; and it is my firm
conviction that inattention to this simple rule, is the source of much of
the failure, which is experienced by some of those who attempt the growth
of plants, at any other than that, which may be regarded as their natural
season of growth. It appears to me, most unreasonable, to aim at attaining
any particular point of the thermometer, merely because any particular
season of the year may be present, or any particular stage of growth
attained. Even if in the sunny climes, from whence the Cucumber has been
transmitted to us, there exists such an equality of temperature and
atmospheric serenity, as some cultivators attempt in the growth of these
plants; it surely cannot be consistent in us to equalize and elevate the
temperature of our artificial at
