regard it as other than incidental. 
One might indulge the conjecture that this accidental feature of a 
snare of Epeira offers a clue to the reason for the permanent features of 
a like character upon the webs of Argiope, Acrosoma, and Uloborus. The 
difference or differences which haye caused the characteristics to become 
fixed in the last named genera are at present unknown. I venture only 
to suggest that my observation shows that these genera quite habitually 
remain upon their orbs

On one occasion while driving 
along a New Jersey road, I observed an orbweb spun upon the tall grass 
beneath a young tree. The foundation lines and supports reached upwards 
to the lowest branch, about twelve feet above the surface. Having climbed 
out upon the branch I observed a spider nested within a curled leaf and
