"The STINGY farmer--an epithet justly and feelingly bestowed by Virgil.
Avaricious, blind, indeed, who proscribes the birds--those destroyers of
insects, those defenders of his harvests. Not a grain for the creature
which, during the rains of winter, hunts the future insect, finds out
the nests of the larvae, examines, turns over every leaf, and destroys,
every day, thousands of incipient caterpillars. But sacks of corn for
the mature insect, whole fields for the grasshoppers, which the bird
would have made war upon. With eyes fixed upon his furrow, upon the
present moment only, without seeing and without foreseeing, blind to the
great harmony which is never broken with impunity, he has everywhere
demanded or approved laws for the extermination of that necessary ally
of his toil--the insectivorous bird. And the insect has well avenged the
bird. It has become necessary to revoke in haste the proscription. In
the Isle of Bourbon, for instance, a price was set on the head of the
martin; it disappeared, and the grasshopper took possession of the
island, devouring, withering, scorching with a biting drought all that
they did not consume. In North America it has been the same with the
starling, the protector of Indian corn. [Footnote: I hope Michelet has
good authority for this statement, but I am unable to confirm it.] Even
the sparrow, which really does attack grain, but which protects it still
more, the pilferer, the outlaw, loaded with abuse and smitten with
curses--it has been found in Hungary that they were likely to perish
without him, that he alone could sustain the mighty war against the
beetles and the thousand winged enemies that swarm in the lowlands; they
have revoked the decree of banishment, recalled in haste this valiant
militia, which, though deficient in discipline, is nevertheless the
salvation of the country. [Footnote: Apropos of the sparrow--a single
pair of which, according to Michelet, p. 315, carries to the nest four
thousand and three hundred caterpillar or coleoptera in a week--I find
in an English newspaper a report of a meeting of a "Sparrow Club,"
stating that the member who took the first prize had destroyed 1,467 of
these birds within the year, and that the prowess of the other members
had brought the total number up to 11,944 birds, besides 2,553 eggs.
Every one of the fourteen thousand hatched and unhatched birds, thus
sacrificed to puerile vanity and ignorant prejudice, would have saved
his bushel of wheat by preying upon insects that destroy the grain.]
