. American spiders and their spinning work. A natural history of the orbweaving spiders of the United States, with special regard to their industry and habits. Spiders. runs along the dragline to fig. us. section of loumiation um- spiilur. Natural orb of the Orchard which she hangs underneath the hub, to the remotest part of her foundation lines, with which the drag- line is generally comiected. She remains stationary, at her point of refuge, or hides beneath a leaf, or sometimes drops to the earth. I have never seen the snare of Hortorum in a vertical position, and have rarely noticed it inclined in any degree from the horizontal; but have record of one web that inclined about forty-five degrees. In this orb the foundation lines were attached to the leaves of a plant eighteen inches high, upon which the snare was hung. From these, retitolarian lines were carried downward to an adjoining tree, making a rude appearance of an inverted pyramid. This apron was not carried up close to the orb, but separated from it about the distance of five or six inches. This is the ordi- nary position of the ajiron, and in this respect is quite analogous to the corresponding situation of orb and labyrinth in the snare of Epeira labyrinthea. Indeed, it nniy be said as a general fact that. Fii;. 144.
