of fagots.  But she did not tell that she had been in the thickest part of the wood and had removed the earth at the base of certain young trees, round which she had then cut off a ring of bark, replacing the earth, moss, and dead leaves just as they were before she touched them.  It was impossible that any one could discover this annular incision, made, not like a cut, but more like the ripping or gnawing of animals or those destructive insects called in different regions borers, or turks, or white worms, which are the first stage of cockchafers.  These destructive pests are fond of the bark of trees; they get between the bark and the sap-wood and eat their way round.  If the tree is large enough for the insect to pass into its second state (of larvae, in which it remains dormant until its second metamorphose) before it has gone round the trunk, the tree lives, because so long as even a small bit of the sap-wood remains covered by the bark, the tree will still grow and recover itself.  To realize to what a degree entomology affects agriculture, horticulture, and all earth products, we must know that naturalists like Latreille, the Comte Dejean, Klugg of Berlin, Gene of Turin, etc., find that the vast majority of all known insects live at the sacrifice of vegetation; that the coleoptera (a catalogue of which has lately been published by Monsieur Dejean) have twenty-seven thousand species, and that, in spite of the most earnest research on the part of entomologists of all countries, there is an enormous number of species of whom they cannot trace the triple transformations which belong to all insects; that there is, in short, not only a special insect to every plant, but that all terrestrial products, however much they may be manipulated by human industry, have their particular parasite.  Thus flax, after covering the human body and hanging the human being, after roaming the world on the back of an army, becomes writing-paper; and those who write or who read are familiar with the habits and morals of an insect called the “paper-louse,” an insect of really marvellous celerity and behavior; it undergoes its mysterious transformations in a ream of white paper which you have carefully put away; you see it gliding and frisking along in its shining robe, that looks like isinglass or mica,—­truly a little fish of another element.

The borer is the despair of the land-owner; he works underground; no Sicilian vespers for him until he becomes a cockchafer!  If the populations only realized with what untold disasters they are threatened in case they let the cockchafers and the caterpillars get the upper hand, they would pay more attention than they do to municipal regulations.
