I end by possessing some hundreds of sheets representing the mushrooms of the neighborhood in their natural size and colors. My collection has a certain value. If it lacks artistic finish, at least it boasts the merit of accuracy. It brings me visitors on Sundays, country people, who stare at it in all simplicity, astounded that such fine pictures should be done by hand, without a copy and without compasses. They at once recognize the mushroom represented; they tell me its popular name, thus proving the fidelity of my brush. Well, what will become of this great pile of drawings, the object of so much work? No doubt, my family will keep the relic for a time; but, sooner or later, taking up too much space, shifted from cupboard to cupboard, from attic to attic, gnawed by the rats, foxed, dirtied and stained, it will fall into the hands of some little grandnephews who will cut it into squares to make paper caps. It is the universal rule. What our illusions have most fondly cherished comes to a pitiful end under the claws of ruthless reality. CHAPTER XVIII. INSECTS AND MUSHROOMS It were out of place to recall my long relations with the bolete and the agaric if the insect did not here enter into a question of grave interest. Several mushrooms are edible, some even enjoy a great reputation; others are formidable poisons. Short of botanical studies that are not within everybody's reach, how are we to distinguish the harmless from the venomous? There is a widespread belief which says that any mushroom which insects, or, more frequently, their larvae, their grubs, accept can be accepted without fear; any mushroom which they refuse must be refused. What is wholesome food for them cannot fail to be the same for us; what is poisonous to them is bound to be equally baneful to ourselves. This is how people argue, with apparent logic, but without reflecting upon the very different capabilities of stomachs in the matter of diet. After all, may there not be some justification for the belief? That is what I purpose examining. The insect, especially in the larval stage, is the principal devourer of the mushroom. We must distinguish between two groups of consumers. The first really eat, that is to say, they break their food into little bits, chew it and reduce it to a mouthful which is swallowed just as it is; the second drink, after first turning their food into a broth, like the bluebottles. The first are the less numerous. Confining myself to the results of my observations in the neighborhood, I count, all told, in the group of chewers, four beetles and a moth caterpillar. To these may be added the mollusk, as represented by a slug, or, more specifically, an arion, of medium size, brown and adorned with a red edge to his mantle. A modest corporation, when all is said, but active and enterprising, especially the moth.
