THE FOREST AND THE HARVEST
The scene at Conches had, apparently, a good effect on the peasantry;
on the other hand, the count's faithful keepers were more than ever watchful that only dead wood should be gathered in the forest of Les Aigues.But for the last twenty years the woods had been so thoroughly cleared out that very little else than live wood was now there; and this the peasantry set about killing, in preparation for winter, by a simple process, the results of which could only be discovered in the course of time.Tonsard's mother went daily into the forest; the keepers saw her enter; knew where she would come out; watched for her and made her open her bundle, where, to be sure, were only fallen branches, dried chips, and broken and withered twigs.The old woman would whine and complain at the distance she had to go at her age to gather such a miserable bunch 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.
Holland came near perishing; its dikes were undermined by the teredo, and science is unable to discover the insect from which that mollusk derives, just as science still remains ignorant of the metamorphoses of the cochineal.The ergot, or spur, of rye is apparently a population of insects where the genius of science has been able, so far, to discover only one slight movement.Thus, while awaiting the harvest and gleaning, fifty old women imitated the borer at the feet of five or six hundred trees which were fated to become skeletons and to put forth no more leaves in the spring.They were carefully chosen in the least accessible places, so that the surrounding branches concealed them.
Who conveyed the secret information by which this was done? No one.
Courtecuisse happened to complain in Tonsard's tavern of having found a tree wilting in his garden; it seemed he said, to have a disease, and he suspected a borer; for he, Courtecuisse, knew what borers were, and if they once circled a tree just below the ground, the tree died.
Thereupon he explained the process.The old women at once set to work at the same destruction, with the mystery and cleverness of gnomes;
and their efforts were doubled by the rules now enforced by the mayor of Blangy and necessarily followed by the mayors of the adjoining districts.
The great land-owners of the department applauded General de Montcornet's course; and the prefect in his private drawing-room declared that if, instead of living in Paris, other land-owners would come and live on their estates and follow such a course together, a solution of the difficulty could be obtained; for certain measures, added the prefect, ought to be taken, and taken in concert, modified by benefactions and by an enlightened philanthropy, such as every one could see actuated in General Montcornet.
