, p. 135.—The aeronautic or ballooning habit of spiders is the basis of these engineering feats of the Pixies Lycosa and Gossamer. A pleasant October day is the best on which to observe it; but young spiders may be seen in aeronautic flight during all warm months. An elevated spot is usually sought from which to make the ascent. Ground spiders, as Lycosids, ascend in the manner shown Fig. 57; Orbweavers drift off as at Fig. 59. This interesting habit is described more at length in my "Tenants of an Old Farm."
