Who is there that does not admire, for more reasons than one, the labor of the spiders, which seems as pattern for the threads that women spin and the nets that are used in hunting? For the extraordinary fineness of the spinning, and the evenness of the thread, not discontinued or snapped off like the yarn upon a quill, but having the smooth and subtle texture of a thin membrane, and knit and spun together with a certain clammy moisture imperceptibly mixed; besides the tincture of it, causing a kind of airy and misty color, the better to deceive; but above all, the conduct and governing of this little engine, in which when any thing happens to be entangled, you see how presently, like an expert huntsman, the subtle artist contracts her net and binds her prey within it;—all this being every day obvious to our sight and contemplation gives credit to my discourse, which otherwise might be accounted no less fabulous than what is reported of certain Libyan crows, that, when they are a-thirsty, throw stones into the water, by that means to raise it to such a height that they may be able to reach it with their bills. Then again, when I saw a ship dog, in the absence of the seamen, putting in stones in a half-empty jar of oil, it was to me a wonder how that dog should understand that the pressure of the heavier weight would make the lighter rise. And the same artifices are reported of Cretan bees and Cilician geese. For the first of these, being to take their flight about some windy promontory, ballast themselves with little stones, to prevent their being carried away by the stronger blasts. And as for the geese, they being afraid of the eagles, every time they cross the mountain Taurus, carry great stones in their mouths, to the end that by that means (as it were) bridling their gaggling tongues, they may cross the mountain in silence, without alarming their enemies. Extraordinary also is the caution which the cranes observe in their flight. For they fly, when the wind is very high and the air very tempestuous, not as in fair weather, all afront or in manner of the half-moon; but forming a triangular body, with the sharp angle of that figure they penetrate the wind that ruffles round about them, and by that means preserve their order unbroken. On the other side, when they fall upon the ground, those that are upon the night-watch stand with the whole weight of their bodies upon one leg, holding a stone in the claw of the other foot. For the holding of the stone keeps them awake for a long time together, and wakes them again with the noise of the fall if they happen to drop asleep. So that it was no wonder that Hercules laid his quiver under his arm-pit, and with his strenuous arm embracing his bow, Slept all the night, where’er he laid his load, With his right-handed weight upon the wood.
