With difficulty and unheard-of trouble, it succeeded in fixing, at some distance above the net, thirty of the white points, of which I told you before. These served as fixtures for a roof, which was constructed down to the net, rounded, fashioned little by little like a horn, furnished with threads finer, silkier, more closely woven, and more deeply colored, and thus became a nest impenetrable to the eye, and impervious to moisture. Some drops of water poured on this dwelling glided down its walls without penetrating them the least in the world, fell in trembling pearls through the net, and stopped at the bottom of the vase, where they evaporated. The spider had drawn the threads, which an approximative calculation might estimate, without exaggeration, at two thousand feet in length, from six spinners attached to the abdomen, and which secrete a grayish fluid, instantly transformed, by contact with the air, into silky threads, and of astonishing strength, if we consider their tenuity! A single spider's-thread, if not broken by a shock, will sustain a weight of 270 grains! Once his establishment finished, the spider took to passing the days and nights on the threshold of his dwelling, waiting with unexampled patience until chance should bring him some prey. This, however, did not happen; flies were yet scarce, and there was nothing in the vase of a kind to attract them. Two months rolled by, during which the poor animal grew remarkably thin. At last, one day, moved by compassion, the observer threw a fly to the famished creature. The little insect fell on the net, caught its wings in the invisible meshes, which covered the principal tissue, and struggled violently. Immediately the spider ran up, quickly but heavily, seized its prey with its eight feet at once, griped it with its formidable jaws, shaped like a hook, and dragged the body into his nest. An hour after he brought out of his house the remains of the fly, and threw them into the obscurest corner, the one most distant from his web, nor did he leave them without covering them with tissue, so as to hide entirely from sight the aspect of his charnel-house. Thus Brutus cast his mantle over the body of Cæsar. Every day, at the same hour, the observer threw a fly into the vase. It was not long before he perceived that the spider, as soon as the time for its repast arrived, came out of its retreat, advanced over the web, watched for the fall of the fly, and was no more frightened at the movement, which before caused it to fly and return to its dwelling, when the provider's hand brought its dinner.
