But, as soon as victuals are plentiful, there comes from every side a rush of consumers only too eager to reduce the headlong production. The Field-mouse, a native, hoards acorns in a stone-heap, near her hay mattress. A stranger, the Jay, arrives from a distance, in flocks, apprised I know not how. For some weeks he flies feasting from oak to oak, giving vent to his joys and his emotions by screeching like a strangled Cat; then, having fulfilled his mission, he goes back to the north whence he came.
The Weevil has been beforehand with them all. She confided her eggs to the acorns while these were still green. They are now lying on the ground, brown before their time and pierced with a round hole through which the larva has escaped after consuming the contents. It would be easy under a single oak to fill a basket with these empty ruins. The Weevil has done more than the Jay and more than the Field-mouse to get rid of the superfluity.
Soon man arrives, thinking of his pigs. In my village it is a great event when the public crier announces the opening day for gathering acorns in the common woods. The more zealous inspect [[88]]the ground on the eve, in order to select a good place. Next morning, at peep of day, the whole family is there. The father beats the higher branches with a pole; the mother, wearing a large canvas apron which allows her to force her way through the thickets, gathers from the tree all that her hand can reach; the children pick up what lies on the ground. And the baskets are filled, followed by the hampers and the sacks.
After the glee of the Field-mouse, the Jay, the Weevil and so many others, here comes that of man, calculating how much bacon his harvest will bring him. One regret mingles with the rejoicings, that is to see so many acorns scattered on the ground, pierced, spoilt, good for nothing. Man inveighs against the author of the damage. To listen to him, you would think that the forest were his alone and that the oaks bore fruit only for his Pig.
‘My friend,’ I would say to him, ‘the forest-ranger can’t summon the delinquent and this is just as well, for our self-seeking, which is inclined to look upon the acorn-crop only in the light of a string of sausages, would lead to tiresome results. The oak invites the whole world to enjoy its fruits. We take the biggest share, because we are the strongest. That is only our right.… But what ranks ever so much higher is a fair division among the various consumers, great and small, all of whom play their part in this world. If it is well [[89]]that the Blackbird should whistle and gladden the burgeoning of the spring, then let us not take it ill that the acorns are rotten. For here the Blackbird’s dessert is prepared, the Weevil, a dainty mouthful that lends fat to his rump and music to his throat.’
Let us leave the Blackbird to sing and hark back to the Weevil’s egg. We know where it is: at the base of the acorn, in the tenderest and juiciest part of the fruit. How did it get there, so far from the entrance, which is situated above the edge of the cup. A very small question, it is true, even puerile, if you will. Let us not despise it: science is built up of puerilities.
The first man to rub a piece of amber on his sleeve and thereupon to discover that the piece aforesaid attracted bits of straw certainly did not suspect the electric wonders of our day. He was amusing himself in his artless fashion. When repeated and tested in every conceivable manner, this child’s plaything became one of the forces of the world.
The observer must neglect nothing: he never knows what the humblest fact may bring forth. I therefore repeat the question: by what means was the Weevil’s egg placed so far from the entrance?
To any one who was not yet aware of the position of the egg, but who knew that the grub attacks the base of the acorn first, the reply would appear to [[90]]be as follows: the egg is laid at the entrance of the tunnel, on the surface; and the grub, crawling along the gallery dug by the mother, of its own accord reaches the point where its infant’s-food exists.
At first, before I possessed adequate particulars, this explanation was also my own; but the mistake was soon dispelled. I pluck the acorn when the mother withdraws after for an instant applying the tip of her abdomen to the orifice of the tunnel which her rostrum has just bored. The egg, so it seems, must be there, at the entrance, close to the surface.… But not at all: it is not there; it is at the other end of the passage! If I dared to take the liberty, I should say that it has gone down it as a stone falls to the bottom of a well.
