In this exalted position she sits for sometime laying her plans with due regard to the locality; she consults the weather, ascertains if the night will be fine. Then, suddenly, with her eight legs widespread, she lets herself drop straight down, hanging to the line that issues from her spinnerets.
The Spider's front tarsi are the motor; the revolving spool is the captured insect; the steel eyelet is the aperture of the spinnerets. To bind the subject with precision and dispatch nothing could be better than this inexpensive and highly effective method. Less frequently, a second process is employed.
The chawing-up of that wasp was a sight to behold. I have no great sympathy with wasps they have done me so many bad turns in my time that I don't pretend to regard them as deserving of exceptional pity but I must say Eliza's way of going at them was unduly barbaric. She treated them for all the world as if they were entirely devoid of a nervous system. I wouldn't treat a Saturday Reviewer myself as that spider treated the wasps when once she was sure of them. She went at them with a sort of angry, half-contemptuous dash, kept cautiously out of the way of the protruded sting, began in most business-like fashion at the head, and rolling the wasp round and round with her legs and feelers, swathed him rapidly and effectually, with incredible speed, in a dense network of web poured forth from her spinnerets. In less than half a minute the astonished wasp, accustomed rather to act on the offensive than the defensive, found himself helplessly enclosed in a perfect coil of tangled silk, which confined him from head to sting without the possibility of movement in any direction. The whole time this had been going on the victim, struggling and writhing, had been pushing out its sting and doing the very best it knew to deal the wily Eliza a poisoned death-blow. But Eliza, taught by ancestral experience, kept carefully out of the way; and the wasp felt itself finally twirled round and round in those powerful hands, and tied about as to its wings by a thousand-fold cable. Sometimes, after the wasp was secured, Eliza even took the trouble to saw off the wings so as to prevent further struggling and consequent damage to the precious web; but more often she merely proceeded to eat it alive without further formality, still avoiding its sting as long as the creature had a kick left in it, but otherwise entirely ignoring its character as a sentient being in the most inhuman fashion. And all the time, till the last drop of his blood was sucked out, the wasp would continue viciously to stick out his deadly sting, which the spider would still avoid with hereditary cunning. It was a horrid sight a duel
Let us first suppose the usual case, that of an average head of game, a Moth or Fly of some sort. Facing her prisoner, the Spider contracts her abdomen slightly and touches the insect for a moment with the end of her spinnerets; then, with her front tarsi, she sets her victim spinning. The Squirrel, in the moving cylinder of his cage, does not display a more graceful or nimbler dexterity.
The silk disk, a sort of hardy concave paten, now no longer receives anything from the spinnerets in its centre; the marginal belt alone increases in thickness. The piece thus becomes a bowl-shaped porringer, surrounded by a wide, flat edge. The time for the laying has come.
The spinnerets distribute the material with a wide longitudinal swing, from pole to pole; and the hind-legs apply it in capricious ribbons. When this is done, the work is finished. The Spider moves away with slow strides, without giving a glance at the bag. The rest does not interest her: time and the sun will see to it. She felt her hour at hand and came down from her web.
One would have thought that she would recognize her mistake with those eight eyes of hers, which gleam like precious stones. The silly creature pays no attention. Lovingly she embraces the cork ball, fondles it with her palpi, fastens it to her spinnerets and thenceforth drags it after her as though she were dragging her own bag. Let us give another the choice between the imitation and the real.
We would venture to regard the ovipositor of insects as probably representing three pairs of abdominal legs, comparable with those of the Myriopods, and even, as we have suggested in another place, the three pairs of jointed spinnerets of spiders.
To evolve the silk glands would have required, as for most other organs, a long period of incipiency, during which they would have been useless. We can not assume that a substance so exceptional in its character as the web of the spider could have been suddenly produced by evolution. But the glands would be useless without spinnerets.
Her neighbour, a little later, does better than this: while the huntress is prowling about in the neighbourhood of the funnel, she suddenly leaps out of the tube, with the lifeline which will save her from falling, should she miss her footing, attached to her spinnerets; she rushes forward and hurls herself in front of the Pompilus, at a distance of some eight inches from her burrow.
