CHAPTER XXVIII

THE CHASE

[Illustration: Damsel-fly]

UNCLE PAUL had said: “Let us get up early in the morning.” No one had to

be called. One sleeps little when one is going to see an epeira hunt.

About seven o’clock, with the sun shining bright, they were at the

border of the stream. The cobweb was finished. Some dewdrops hanging to

the threads shone like pearls. Hence the spider was not yet in the

center of the net; no doubt it was waiting, before descending from its

room, for the sun to dissipate the morning dampness. The party sat down

on the grass for breakfast, at the very foot of the alder-tree to which

were fastened the cables of the net. Blue damsel-flies flew from one

tuft of rushes to another and chased each other playfully. Beware, you

giddy ones, who will not know how to avoid the web by passing over and

under it! Ah! it has happened; so much the worse for the victim. When

one plays foolishly with one’s companions, one must at least look where

one is going. A dragon-fly is caught in the meshes of the web. With one

wing free it struggles to escape. It shakes the web, but the cables hold

in spite of the shaking. Threads in communication with the resting-room

warn the epeira, by their agitation, of the important things taking

place in the net. The spider hastily descends, but it does not get there

in time. With a desperate stroke of its wing the dragon-fly frees itself

and escapes, tearing a large hole in the web.

“Oh! how well it got out!” cried Jules. “A little more and the poor

thing would have been eaten alive. Did you see, Emile, how quickly the

spider ran down from its hiding place when it felt the web move? The

hunt begins badly; the game escapes and the net is torn.”

“Yes, but the spider is going to mend it,” his uncle reassured him.

And, in fact, as soon as it had recovered from its misadventure, the

epeira renewed the broken threads with delicate dexterity. The darning

finished, the damage could hardly be detected. The spider now takes its

place in the center of the network: the right moment for the chase has

come, apparently, and it is advisable for it to pounce upon the game as

quickly as possible, to avoid other misadventures. It spreads its eight

feet in a circle, to receive the slightest movement that may come at any

point of the web, and it waits, completely motionless.

The dragon-flies continue their evolutions. Not one is caught: the

recent alarm has rendered them circumspect; they fly around the web to

pass beyond it. Oh! oh! what is that coming so giddily and striking its

head against the network? It is a little bumble-bee, all velvety and

black, with a red stomach. It is caught. The epeira runs. But the

captive is vigorous and formidable; perhaps it has a sting. The spider

mistrusts it. It draws a thread from its spinneret and passes it quickly

over the bee. A second silk string, a third, a fourth, soon subdue the

captive’s desperate efforts. Here is the bee strangled but still full of

life, and menacing. To seize it in that state would be great imprudence:

the epeira’s life would be at stake. What must be done so as to leave

nothing to fear from this dangerous prey? The spider possesses, folded

under its head, two sharp-pointed fangs, which let flow a little drop of

poison through a hole in their extremities. That is its hunting weapon.

The epeira approaches cautiously, opens its fangs, stings the bee, and

immediately moves aside. In the twinkling of an eye it is all over. The

poison acts instantly: the bee trembles, its legs stiffen, it is dead.

The spider carries it off to its silken chamber to suck it at leisure.

When nothing but the skin is left, the spider will throw the remains of

the bee far from its domicile, so as not to soil its web with a corpse

that might frighten other game.

“It was done so quickly,” complained Jules, “I did not see the spider’s

poisonous fangs. If we were to wait a little longer, another bumble-bee

might perhaps come and then I should see it better.”

“It is not necessary to wait,” replied Uncle Paul. “If we proceed

skilfully we can make the spider recommence its hunting manœuvers. All

of you look attentively.”

Uncle Paul searched among the field flowers for a moment and caught a

large fly; then, holding it by one wing, put it near the web. The

insect, beating about, gets entangled in the threads. The web shakes,

the spider leaves its bee and runs, delighted with the fortunate chance

that brings him prey again so quickly. The same manœuvers begin again.

The fly is first strangled; the epeira opens its pointed fangs, stings

the fly a little, and all is over. The victim trembles, stretches itself

out, and ceases to move.

“Ah! that time I saw it,” said Jules, satisfied at last.

“Claire, did you notice the fineness of the spider’s fangs?” asked

Emile. “I am sure that in your needle-case you haven’t any such

fine-pointed needles.”

“I dare say not. As for me, what surprises me the most is not the

fineness of the spider’s fangs, but the quickness of the victim’s death.

It seems to me that a fly as large as this one ought not to die so

quickly even from the coarser pricks of our needles.”

“Very true,” assented her uncle. “An insect transfixed by a pin still

lives a long time; but if it is only pricked by the fine point of the

spider’s fangs, it dies almost instantly. But then, the spider takes

care to poison its weapon. Its fangs are venomous; they are perforated

by a minute canal through which the spider lets flow at will a scarcely

visible little drop of liquid called venom, which the creature makes as

it makes the silk liquid. The venom is held in reserve in a slender

pocket placed in the interior of the fangs. When the spider pricks its

prey, it makes a little of this liquid pass into the wound, and that

suffices to bring speedy death to the wounded insect. The victim dies,

not from the prick itself, but from the dreadful ravages wrought by the

venom discharged into the wound.”

Here Uncle Paul, in order to give his hearers a better view of the

poisonous fangs, took the epeira with the tips of his fingers. Claire

uttered a cry of fear, but her uncle soon calmed her.

“Don’t be uneasy, my dear child: the poison that kills a fly will have

no effect on Uncle Paul’s hard skin.”

And with the aid of a pin he opened the creature’s fangs to show them in

detail to the children, who were quite reassured.

“You must not be too frightened,” he continued, “at the quick death of

the fly and of the bumble-bee, and so look on spiders as creatures to be

feared by us. The fangs of most of them would have great difficulty in

piercing our skin. Courageous observers have let themselves be bitten by

the various spiders of our country. The sting has never produced any

serious results; nothing more than a redness less painful than that

produced by the sting of a mosquito. At the same time, persons with a

delicate skin ought to beware of the large kinds, were it only to spare

themselves a passing pain. Without any excessive alarm we avoid the

wasp’s sting, which is very painful; let us avoid the spider’s fangs in

the same way without uttering loud cries at the sight of one of these

creatures. We will resume the subject of the venomous insects. But it is

late; let us go.”
