      The hearing and touch of this spider are very acute. The latter is exercised by the palpi and the tips of the legs, especially the first pair, but no ear has yet been discovered; neither is anything known of the organs of taste and smell, or even whether the insect possesses these senses at all.

      I ought before this to have anticipated and answered a question which nine out of ten, perhaps, of my readers have already asked themselves, "Do not spiders bite? and is not their bite poisonous, nay, at times, deadly even to man?" The answer is, in brief, Yes, spiders do bite, probably all of them, if provoked and so confined that they cannot escape; though only a few tropical species can be said to seek of their own accord an opportunity for attacking man, or any creature larger than the insects that form their natural prey. Even the Nephila plumipes, which, it has been intimated, is "Christian in its disposition, and well-behaved beyond most of its kind," will readily bite, if it is held in the fingers and anything is put to its jaws. But that is nothing. So would you, most gentle reader, if a great giant pinched you between his thumb and finger, and held your hands and feet and head; and if, too, like our spider, you could not see enough to distinguish friends from foes. Spiders, then, will bite. But to the second part of the inquiry our answer must be less positive. They have a very bad name; but much of this is due to their grim and forbidding aspect, and their bloody trade of trapping and eating poor little insects. It is to be remembered that there are very few, if any, medical reports of injuries from the bites of spiders, and that the accounts of such cases occurring in the newspapers consist in great measure of inference, and either make no mention of the offender at all, or merely speak of a little black or gray spider being found in the vicinity. A number of experiments have been made in England to ascertain the effect of the bite of the larger geometrical spiders upon the experimenter himself, upon other spiders, and upon common insects; and the conclusion was, that it produces no greater effect than the prick of a pin, or any other injury of equal extent and severity; while the speedy death of its victim is ascribed to the spider's sucking its juices, rather than to any poison instilled into the wound. But these experiments, though somewhat reassuring, are not conclusive; for they were tried only on one person, and people vary much in their susceptibility to poison of all kinds; moreover, the spiders employed were of the geometrical kinds, which have never been so much feared as the larger field and hunting spiders. Indeed, it may be found that among spiders there is as great a difference in respect to venom as among serpents, and that those which depend upon their jaws for taking and holding their prey, such as the field and hunting spiders, are poisonous, while the web-builders which ensnare their victims are not so. In regard to our spiders, I have caused a large one to bite, so as to draw blood, a kitten three days old, and the kitten has not appeared to suffer in the least on that account.

      They are very quiet insects, and never appear disturbed at what goes on about them; neither do they run away and hide in holes and corners, like our common spiders; but if their webs are injured, or they are startled by a noise, they will shake themselves from side to side in their webs, so as to be wholly invisible. Their natural food is insects of all kinds; but they soon learn to eat soft flesh, such as the liver of chickens, for which, as well as for water, they will sometimes stretch themselves and turn in their webs so as to take it from the point of a pin or camel's-hair pencil. Besides water to drink, they require an atmosphere saturated with moisture, like that of their native island, the relative humidity being about seventy on the Hygrodeik scale. If stroked upon the back, they often raise their bodies as a cat does, and sometimes put back a leg to push away your finger. They may be allowed to run over one's person with perfect safety, but, if suddenly seized, will hold on with tooth as well as nail.

      They are quite economical, and every few days, when the web has become too dry and dusty for use, will gather it up in a mass, which they stuff into their jaws and masticate for hours, swallowing the gum, but throwing out the rest, with the little particles of dust, in the form of a hard black pellet,—an instance rare, if not indeed unique, of an animal eating a substance already excreted from its body.

      Here I must close, though much against my will. It would please me to describe, as it has almost fascinated me to observe, the doings of my spiders, as they grew older and made their webs in the Wardian cases to which they were removed when too many and too large for the jars; how the young are gregarious, and move from place to place in a close column, protected on all sides by skirmishers, which continually report to the main body; how some of these young, whose parents were caught on Long Island, South Carolina, a year ago, and which were hatched from the egg in October last, have grown up during a Northern winter, have themselves become parents and laid eggs; how they periodically cast off their skins, even to that of the eyes, the jaws, and the breathing tubes, and how, from too great impatience, sad accidents sometimes befall them on these occasions; how, also, I have reeled silk from several of these spiders, and made a thread which has been woven in a power-loom as a woof or filling upon a warp of common black silk, so as to make a bit of ribbon two inches wide, thereby proving that it is real silk and can be treated as such.

      Much, too, could be said of the only other attempts to utilize spiders' silk, a knowledge of which would have materially aided me. In France, one hundred and fifty years ago, M. Bon made gloves and stockings of silk got by carding spiders' cocoons, and seventy years later, as I have but recently ascertained, Termeyer, a Spaniard, not only used the cocoons, but also, by an observation similar to my own, was led to reel the silk from the living insect. He, however, had poorer spiders or too little perseverance, or friends and a government influenced by a most short-sighted economy and prudence, else the highly interesting and instructive account of his experiments would have been familiar to some one in this country, and would not have waited these many years to be found by accident last spring in an obscure corner of the Astor Library.

      I will add, finally, that I believe some other geometrical spiders, especially of the genus Nephila, may be found as docile, and as productive of beautiful silk, as the species I have described. At any rate, you cannot find a more interesting inmate of your Wardian case than some large geometrical spider.

      WHAT DID SHE SEE WITH?

      I could not have been more than seven or eight years old, when it happened; but it might have been yesterday. Among all other childish memories, it stands alone. To this very day it brings with it the old, utter sinking of the heart, and the old, dull sense of mystery.

      To read the story, you should have known my mother. To understand it, you should understand her. But that is quite impossible now, for there is a quiet spot over the hill, and past the church, and beside the little brook where the crimsoned mosses grow thick and wet and cool, from which I cannot call her. It is all I have left of her now. But after all, it is not of her that you will chiefly care to hear. The object of my story is simply to acquaint you with a few facts, which, though interwoven with the events of her life, are quite independent of it as objects of interest. It is, I know, only my own heart that makes these pages a memorial,—but, you see, I cannot help it.

      Yet, I confess, no glamour of any earthly love has ever utterly dazzled me,—not even hers. Of imperfections, of mistakes, of СКАЧАТЬ
