The eyes, eight in number, are divided into three groups. In the middle of that weird segment which is at once head and thorax, two large and very convex eyes gleam side by side, reminding us of the Lycosa’s[5] superb lenses; they are apparently in both instances for use at close range, because of their great convexity. A ridge of protuberances arranged in a wavy line serves as an eyebrow and gives them a fierce appearance. Their axis, which is almost horizontal, can hardly allow them more than lateral vision.
The same remark applies to two other groups, each composed of three eyes, which are very small and placed much farther forward, nearly on the edge of the sudden truncation that forms an arch above the mouth. On both right and left the three tiny lenses are set in a short straight line, their axis pointing laterally. On the whole, both the small and the large eyes are so arranged that [[13]]it can by no means be easy for the animal to obtain a clear view ahead.
Extremely short-sighted and squinting outrageously, how does the Scorpion manage to steer himself? Like a blind man, he gropes his way: he guides himself with his hands, that is to say, his pincers, which he carries outstretched, with the fingers open, to sound the space before him. Watch two Scorpions wandering in the open air in my rearing-cages. A meeting would be disagreeable, sometimes even dangerous for them. Nevertheless, the one behind always goes ahead as though he did not perceive his neighbour; but, as soon as he touches the other ever so little with his pincers, he at once gives a sudden start, a sign of surprise and uneasiness, followed at once by a retreat and a change of direction. To recognize the irascible one thus overhauled, he had to touch him.
Let us now instal our prisoners. I shall never learn all I want to know by turning over stones and making chance observations on the adjacent hills: I must resort to keeping the animals in captivity, the only manner of inducing them to reveal their domestic [[14]]habits. What rearing-method shall I employ? One in particular appeals to me, one which will leave the creature its full liberty, which will relieve me of the cares of catering and which will enable me to inspect my captives at any hour of the day, from year’s end to year’s end. This seems to me an excellent means, far superior to the others, so much so that I reckon on a magnificent success.
It is a question of establishing within my own grounds, in the open air, a hamlet of Scorpions, by cunning securing for them the same conditions of well-being which they enjoyed at home. In the first days of January, I found my colony right at the end of the harmas,[6] in the quiet corner exposed to the sun and sheltered from the north wind by a thick rosemary-hedge. The ground, a mixture of pebbles and red clayey soil, is unsuitable. Considering the temperament of my charges, great stay-at-homes from what I can see, this is easily remedied. For each of my colonists I dig a hole, of a gallon or [[15]]two in capacity, and fill it with sandy earth similar to that of the original site. I pack this earth lightly, which will give it the consistence needed for digging without land-slips, and in it I contrived a short entrance-passage, the beginning of the excavation which the Scorpion will not fail to make in order to obtain a cell in conformity with his tastes. A wide flat stone covers and overlaps the whole. Opposite the passage of my own making, I scoop out a hollow: this is the entrance-door.
In front of the hollow I place a Scorpion, taken that moment from the paper bag in which he has just been conveyed from the mountain. Seeing a retreat similar to those with which he is familiar, he goes in of his own accord and does not show himself again. In this way I establish the hamlet, consisting of some twenty inhabitants, all adults. The dwellings, placed at a suitable distance from one another, to avoid the quarrels liable to occur among neighbours, are arranged in a row on a stretch of ground cleared with the rake. It will be easy for me to observe events at a glance, even at night, by the light of a lantern. As to food, I need not trouble [[16]]about that. My guests will find their own provisions, for the spot is quite as well-stocked with game as that from which I brought them.
The colonies in the paddock are not enough. Certain observations call for minute attention which is incompatible with the disturbances out of doors. A second menagerie is set up, this time on the large table in my study, a table around which I have already covered and am still covering so many miles in pursuit of stubborn knowledge. Bring up the big earthenware pans, my usual apparatus! Filled with sifted sandy earth, each receives two broad potsherds, which, half buried, form a ceiling and represent the refuge under the stones. The establishment is surrounded by the dome of a wire-gauze cover.
Here I house the Scorpions, two by two and of different sexes, as far as I am able to judge. No outward characteristic that I know of distinguishes the males from the females. I take the big bellied specimens for females and the less obese for males. As age intervenes with its variations of stoutness, mistakes are inevitable, unless I first [[17]]open the subject’s paunch, a procedure which would cut short any attempt at rearing. We will allow ourselves to be guided by size, since we have no other means of judging, and house the Scorpions two by two, one corpulent and brown, the other less obese and of a lighter colour. There are certain to be some actual couples among the number.
Here are a few details for the benefit of whoso may care one day to take up similar studies. An animal-breeder’s trade calls for apprenticeship; the experience of others is not unhelpful, especially when the animals in question are dangerous to deal with. It would never do inadvertently to lay a hand on one of my present prisoners who had escaped from his cage and lay skulking among the utensils littering the table. Serious precautions must be taken by those who propose to spend whole years in the company of such neighbours. They are as follows:
The trellis-work dome is fitted deep into the pan and touches the earthenware bottom. Between the two there is a circular space which I fill with clay soil, packed while wet. So fitted, the wire cover is quite immovable; the apparatus runs no risk of coming to [[18]]pieces and yielding a way of escape. On the other hand, if the Scorpions dig deeply on the edges of the earthy space at their disposal, they come upon either the wire-gauze or the pottery, both of which are insuperable obstacles. So we need have no fear of escape.
