The work is arduous, very arduous, for the nut is selected when nearly ripe, to provide the grub with more savoury and more abundant food; it is thick and tough, much more so than the rind of an acorn. If the Acorn-weevil takes half a day to bore her passage, how long must the Nut-weevil’s task be, how patient her persistence! Perhaps her rod is specially hardened. We can temper our drills till they wear away granite; no doubt the Weevil, in the same way, provides her boring-tool with a bit of triple hardness.
Quickly or slowly, the auger sinks into the base of the nut, where the tissues are softer and milkier; it enters obliquely, making a fairly long journey, to prepare for the grub a column of semolina suited to its first needs. Whether boring into nuts or into acorns, the Balanini make the same delicate preparations for the benefit of their offspring.
At length there comes the placing of the egg, right at the bottom of the shaft. Here the strange method which we already know is repeated. With a hinder rostrum, equal in length to the front one and kept hidden away in the abdomen until the moment comes for using it, the mother inserts her egg at the base of the kernel.
I see these nursery precautions only in my [[99]]mind’s eye, but I see them very clearly, enlightened as I am by my examination of the nut converted into a cradle and above all by the method of the Acorn-weevil. Still, I might aim at something better than this; I should like to witness the operation: rather a hopeless ambition, I fear.
In my neighbourhood, indeed, the hazel is scarce and its regular exploiter is almost unknown. Nevertheless, let us make the experiment with the six hazel-trees which I planted in the paddock long ago. First of all we must stock them accordingly.
A valley of the Gard, less parched than the Sérignan hills, provides me with a few couples of the insect. They reach me by post at the end of April, when the nut, still quite light in colour, soft and flattish, is beginning to emerge from the cup in which it is sheathed. The kernel is far from formed; there is just a beginning, a promise of a kernel.
In the morning, in glorious weather, I put the strangers on the leaves of my hazels. The journey has not tried them unduly. They look splendid in their modest drab costume. The moment they are free, they half-open their wing-cases, spread their wings, fold them again and once again unfurl them, without taking flight. These are mere muscular exercises, serving to revive their strength after a long imprisonment. I regard these sports in the sunlight as a good omen: my colonists will not run away. [[100]]
Meantime the nuts are filling out daily and beginning to tempt and entice the children. They are within reach of the smallest, who love to stuff their pockets with them and to crunch them, cracking them between two stones. They receive express injunctions to keep their hands off them. This year, for the sake of the Weevils whose history I wish to learn, the joys of gathering nuts in May will be forbidden.
What sort of ideas can such a prohibition produce in these ingenuous minds? If they were of an age to understand me, I would say:
‘My dears, beware of the great enchantress, Science. If ever one of you—which Heaven forbid—should allow himself to be beguiled by her, let him remember my warning: in exchange for the little secrets which she reveals to us, she demands much graver sacrifices than a handful of nuts.’
