American spiders and their spinningworkA natural history of the orbweaving spiders of the United States, with special regard to their industry and habits . tlie silk, and the bunchof loops is shown against the cocoon. COMPAKATIVE COCOONING INDUSTRIES. 101 During this and the earlier part of her weaving it seemed to me thattlie silk escaped from the posterior pair of spinnerets alone. It came out as white silk with a little yellowish cast in it, bearing a pretty?R^^fTr gloss. The spinnerets were widely flared, and the silk issued in several filaments. The hind leg was thrown upward as thespider moved and seized these filaments with the foot, apparently usingall the spines from the claws upward to the tarsal joint, and even part ofthe metatarsus. The thread was carried away from the abdomen ratherslowly toward the cocoon. (Figs. 194 and 195. i) At the same moment,also, the abdomen approached the cocoon without touching it. Betweenthe spinnerets and the spiders foot the silken filaments were stretchedtaut (Fig. 196), and after the first gentle motion of approximating thecocoon the abdomen was swung in the opposite direction; that is, away.
