A natural history of the orbweaving spiders of the United States, with special regard to their industry and habits CUbiodiversity1121211-9810 Year: 1889 ( COCOON IIFE AND BABYHOOD. 217 A number of cocoons forwarded to me in the early spring, by Mrs. Eigenmann, from San Diego, California, gave me an opportunity to note the tendency of young Orbwcavcrs in outdoor site. The co- Bscap- coons were fixed upon bushes .within the forks of branches, at mg cm jj when the young were just ready to escape. They evi- dently felt the fresh air of the open, as contrasted witli the boxes in which they had been confined, and at once pushed their way from the flossy interior to the outside of the cocoon. Then one adventurous spirit scrambled to a branch and began to as- cend a stem. Another and another followed, each trailing a dragline along the surface, until at last several threads' were merged into one, which the little creatures laid hold of as suc- ceeding numbers emerged from the cocoon. Thus a long line of them appeared climbing up the thread, which at places swung free from the stem, and at others hugged it closely. (Fig. 250.) They reminded me of a watch of sailors following each other up the shrouds of a ship. Here and tliere, at various points, individ- uals would strike out an independent line of progress, and would be sure to be followed by some of their comrades. One might be seen dangling from a leaf by a slender filament; another with elevated abdomen sending out the first lines of a tentative balloon; a third already embarked on an aeronautic venture, swinging free and swaying in the breeze. (Fig. 250.) Tlie general tendency was to ascend ; scarcely a spider went below the point at which the egg sac was fixed. Here and there little groups would form and hang back downward for a while by a few crossed threads; these again would break up, and at last, well
