The goods are duly approved and paid for on the spot, as agreed. To close the transaction in a fitting manner, I take the victuallers to the cages and show them the Beetle rolling his pill. They gaze in wonder at the funny creature that looks as if it were playing with its ball; they laugh at its tumbles and scream with delight at its clumsy struggles when it comes to grief and lies on its back kicking. A charming sight, especially when the lollipops bulging in the youngsters’ cheeks are just beginning to melt deliciously. Thus the zeal of my little collaborators is kept alive. There is no fear of my boarders starving: their larder will be lavishly supplied. Who are these boarders? Well, first and foremost the Sacred Beetle, the chief subject of my present investigations. Sérignan’s long screen of hills might well mark his extreme northern boundary. Here ends the Mediterranean flora, whose last ligneous representatives are the arboraceous heather and the arbutus-tree; and here, in all probability, the mighty pill-maker, a passionate lover of the sun, terminates his arctic explorations. He abounds on the hot slopes facing the south and in the narrow belt of plain sheltered by that powerful reflector. According to all appearances, the elegant Gallic Bolboceras and the stalwart Spanish Copris likewise stop at this line; for both are as sensitive to cold as he. To these curious Dung-beetles, whose private habits are so little known, let us add the Gymnopleuri, the Minotaur, the Geotrupes, the Onthophagi. They are all welcomed in my cages, for all, I am convinced beforehand, have surprises in store for us in the details of their underground business. My cages have a capacity of about a cubic yard. Except for the front, which is of wire gauze, the whole is made of wood. This keeps out any excessive rain, the effect of which would be to turn the layer of earth in my open-air appliances into mud. Over-great moisture would be fatal to the prisoners, who cannot, in their straitened artificial demesne, act as they do when at liberty and prolong their digging indefinitely until they come upon a medium suitable to their operations. They want soil which is porous and not too dry, though in no danger of ever becoming muddy. The earth in the cages therefore is of a sandy character and, after being sifted, is slightly moistened and flattened down just enough to prevent any landslips in the future galleries. Its depth is barely ten or eleven inches, which is insufficient in certain cases; but those of the inmates who have a fancy for deep galleries, like the Geotrupes for instance, are well able to make up horizontally for what is denied them perpendicularly.
