The diving-spider spins its cell in the water; it is composed of closely-woven, strong, white silk, and shaped like half a pigeon's egg, looking something like a diving-bell. Occasionally this nest is allowed to remain partly above water; generally, however, it is totally submerged, and is attached by a great number of irregular threads to some near objects. It is entirely closed, except at the bottom, where there is a large opening. This, however, is sometimes shut, and then the spider may be seen staying peaceably at home, with her head downward; and thus they often remain during the three winter months. No insects are more cleanly in their habits than spiders, although the gummy substance of which their webs are composed, and the rough hairy covering of their bodies, with but few exceptions, render this an arduous task. Whenever they happen to break a thread of their web which they are unable to mend, they roll it up in a little ball, and throw it away, and they regularly comb their legs. In concluding this brief account of the spider family, we can assure our readers, that any time they may bestow on the subject will be amply rewarded by the interest and pleasure they will derive. And, lest any should imagine that the hours thus passed are wasted or misspent, we shall close our article by giving a short history of a man whose life was saved by his knowledge of the habits of a spider. Very many years ago, a Frenchman called Quatreman Disjouval sided with the Dutch in a revolt against the French. For this offense he was cast into prison, where he remained for eight long years, without the most remote prospect of being set at liberty. To while away the dreary hours, he made acquaintance with some spiders who shared his solitary cell, and, having nothing to occupy his mind, he passed the greater part of his time in attentively watching their movements. By degrees he discovered that they only spun their large wheel-like webs in fine weather, or when it was about to set in; while in damp weather they generally disappeared altogether. In the month of December, 1794, when the republican troops were in Holland, a sudden and unexpected thaw set in, and so materially disarranged their general's plans, that he actually thought of withdrawing his army altogether, and accepting the money which the Dutch would gladly have given to have got rid of them. Meantime Disjouval, who thought that any masters would be better than his present ones, ardently hoped that the French would be victorious. Shut up as he was, he contrived to hear all about their intended movements, and, knowing that the weather alone prevented it, he watched his old friends the spiders with redoubled interest. To his infinite delight, he found that a frost was just about to set in, and so severe a one, too, that it would enable the rivers and canals to bear the weight of the baggage and artillery. Somehow or other, he succeeded in having
