Here the spider dwells secure, frequently resting with her legs extended from the entrance of the gallery, ready to spring out upon whatever insect may fall into her sheet net.” The Gossamer Spiders (4ranea obtectriz) have the power of shooting out lines of gossamer, so as to render themselves quite buoyant, and thus they float about, as though they had wings. These abound both in Europe and America.
