No matter: the first three experiments, made when alarms, time after time repeated, had not yet tangled the delicate connecting thread, seem to point to a certain constancy in the Minotaurus household. He and she know each other, find each other in the tumult of events which my mischievous doings force upon them; they show each other a mutual fidelity, a very unusual quality in the insect class, which is but too prone to forget its matrimonial obligations. We recognize one another by our speech, by the sound, the inflection of our voices. They, on the other hand, are dumb, deprived of all means of vocal appeal. There remains the sense of smell. Minotaurus finding his mate makes me think of my friend Tom, the house-dog, who, at his moony periods, lifts his nose in the air, sniffs the breeze and jumps over the garden-walls, eager to obey the distant and magical convocation; he puts me in mind of the Great Peacock Moth, who swiftly covers several miles to pay his homage to the new-hatched maid. The comparison, however, is far from perfect. The dog and the big Moth get wind of the wedding before they know the bride. Minotaurus, on the other hand, has no experience of long pilgrimages, yet makes his way, in a brief circuit, to her whom he has already visited; he knows her, he distinguishes her from the others by certain emanations, certain individual scents inappreciable to any save the enamoured swain. Of what do these effluvia consist? The insect did not tell me; and that is a pity, for it would have taught us things worth knowing about its feats of smell. Now how is the work divided in this household? To discover this is not one of those easy undertakings for which the point of a knife suffices. He who proposes to visit the burrowing insect at home must have recourse to arduous sapping. We have here to do not with the apartment of the Sacred Beetle, the Copris or the others, which is soon laid bare with a mere pocket-trowel: we have to do with a pit the bottom of which can be reached only with a stout spade, sturdily wielded for hours at a stretch. And, if the sun be at all hot, one returns from the drudgery utterly exhausted. Oh, my poor joints, grown rusty with age! To suspect the existence of a fine problem underground and not to be able to dig! The zeal survives, as ardent as in the days when I used to pull down the spongy slopes beloved by the Anthophora; the love of research has not abated, but the strength is lacking. Luckily, I have an assistant, in the shape of my son Paul, who lends me the vigour of his wrists and the suppleness of his loins. I am the head, he is the arm.
