What is the method of our spider? Ages before the advent of the human engineer he followed the same tactics which we now see him performing in every meadow, or even at our window-sill, or on the bouquet upon our table, linking flower with flower, window-sill with garden fence, bush with bush, tree with tree, with his glistening suspension-bridge spanning the stream, river, and meadow. This wiry thread that tightens across our face as we ride in our carriage, and leaves its tingling "snap" upon our nose, what is this but the model suspension cable of Arachne strengthened a hundredfold by the spider which has travelled back and forth over its course for hours perhaps, each trip leaving a fresh strand, one extremity being anchored on yonder oak in the meadow and the other on the church steeple? Such a cable twenty feet in length is a common challenge in our walks in the open wood road, even making a perceptible motion among the leaves and bending twigs on either side ere it yields to our advance. And to the walker who cares to investigate, a silken bridge a hundred feet in length is not a very exceptional find. This bridge-building is not confined to any particular month or season, nor to any one species of spider. The autumn will afford us the best opportunity for observation. At that season the spider-egg tufts are turning out their baby spiders by the millions, each a perfect grown spider in miniature, and apparently as skilled at birth in the peculiar arts of its kind as its parents were in their ripe old age. Here is a troop of them upon this drooping branch of wild grape by the river brink. Its leaves are glistening in the loose, rambling tangle which marks their wanderings. They are evidently not satisfied with their present surroundings, and would seem desirous of getting as far as possible from the neighborhood of their cradle and swaddling-clothes. They are the most independent and self-reliant babies on record. They ask advice from no one--indeed their mother died a year ago, perhaps--but each determines to leave his brothers and sisters, to "see the world" for himself, and paddle his own canoe. Fancy a first trial trip on a tight-rope from the torch of the Statue of Liberty to Governor's Island! Yet such is the corresponding feat accomplished by this self-reliant acrobat, which a few days or perhaps hours ago was but an egg!
