A natural history of the orbweaving spiders of the United States, with special regard to their industry and habits CUbiodiversity1121211-9742 Year: 1889 ( Fig. 308.

The completed tube, with a small cross tube woven at the base. ground. This forms a frame of straight lines, which is the foundation of the tube. (Fig. 308.) The spider now passes within this structure, and, clinging to the threads with her feet, moves her abdomen simultaneously backward and forward and up and down, meanwhile issuing from the spinnerets thickened lines, which adhere to the framework. In other words, the framework constitutes the warp, and the lines issued there- after the woof of her texture. (Fig. 309.) As the threads are drawn out from the spinnerets they are beaten down upon the frame lines by the ' Proceedings Academy Natural Sciences, Philadelphia, 1888, pages 203-18. ' The Nest- ing Habits of the American Purseweb Spider.'
