For the rest, Nature is so far from sharing our prejudices, dislikes, and childish apprehensions, that she seems specially to care for and protect the gnawing species which injuriously interfere with the economy of our small farms and plantations, but which, on the other hand, lend valuable assistance in maintaining the balance of species and keeping down the vegetable accumulation of certain climates. She preserves with watchful anxiety the caterpillars which we destroy. In the case of the oak-grub, she is mindful to glaze over or varnish its eggs, so that, concealed under the withered leaf, and beaten by winds and rains, they may safely brave the winter. The crawling worms make their appearance clothed in and defended by a thick furry garb, which deceives their enemies, until, transformed into moths, they fly to and fro in happy freedom under cover of the night.
For some she invents still greater precautions. Essential agents, undoubtedly, in the transformation of life, they possess, beyond all others, the guarantees of existence which secure them, infallibly, an immortality of race.
The grubs, for instance, alternately viviparous and oviparous, spring into full life in the summer, that they may the more quickly set to work, but are produced in autumn in the shape of an egg, that they may the better endure the cold of winter. Finally, their generous mother reserves for this beloved species an unheard-of gift,—that a moment of love shall give them the fecundity of forty generations!
Creatures so highly privileged have evidently some task to execute, some great and important mission which renders them indispensable, and makes them an essential part of the harmony of the world. Suns are necessary, but so also are gnats. Grand is the order of the Milky Way, and no less so that of the bee-hive. Who knows but that the life of the stars may be of minor importance? I see that some of them vanish, and God dispenses with them. But no genus of the Insect World ever fails to answer to the summons. If a single species of ants should disappear, their loss would be serious, and cause a dangerous gap in the universal economy.
