Our expectations were fulfilled. The Stickleback was dressed in his best: his scales would have paled the lustre of silver; his throat was flashing with the brightest vermilion. On the approach of the great black Horse-leech, the spines on his back and sides started up, as though worked by a spring. In the face of this resolute altitude, the bandit turns tail and slips ignominiously down among the water-weeds. The placid mollusc tribe—Planorbes, Limnæi and other Water-snails—were sucking in the air on the surface of the water. The Hydrophilus and her hideous larva, those pirates of the ponds, darted amongst them, wringing a neck or two as they passed. The stupid crowd did not seem even to notice it. But let us leave the plain and its waters and clamber up the bluff to the plateau above us. Up there, Sheep are grazing and Horses being exercised for the approaching races, while all are distributing manna to the enraptured Dung-beetles. Here are the scavengers at work, the Beetles whose proud mission it is to purge the soil of its filth. One would never weary of admiring the variety of tools wherewith they are supplied, whether for shifting, cutting up and shaping the stercoral matter or for excavating deep burrows in which they will seclude themselves with their booty. This equipment resembles a technical museum where every digging-implement is represented. It includes things that seem copied from those appertaining to human industry and others of so original a type that they might well serve us as models for new inventions. The Spanish Copris carries on his forehead a powerful pointed horn, curved backwards, like the long blade of a mattock. In addition to a similar horn, the Lunary Copris has two strong spikes, curved like a ploughshare, springing from the thorax and also, between the two, a jagged protuberance which does duty as a broad rake. Bubas bubalis and B. bison, both exclusively Mediterranean species, have their forehead armed with two stout diverging horns, between which juts a horizontal dagger, supplied by the corselet. Minotaurus typhœus carries on the front of his thorax three ploughshares, which stick straight out, parallel to one another, the side ones longer than the middle one. The Bull Onthophagus has as his tool two long curved pieces that remind us of the horns of a Bull; the Cow Onthophagus, on the other hand, has a two-pronged fork standing erect on his flat head. Even the poorest have, either on their head or on their corselet, hard knobs that make implements which the patient insect can turn to good use, notwithstanding their bluntness. All are supplied with a shovel, that is to say, they have a broad, flat head with a sharp edge; all use a rake, that is to say, they collect materials with their toothed fore-legs.
