At fairly frequent intervals, the tip of the abdomen is lifted to the mouth of the balloon; and then the spinnerets really touch the fringed edge.  The length of contact is even considerable.  We find, therefore, that the thread is stuck in this star-shaped fringe, the foundation of the building and the crux of the whole, while every elsewhere it is simply laid on, in a manner determined by the movements of the hind-legs.  If we wished to unwind the work, the thread would break at the margin; at any other point, it would unroll.

The Epeira ends her web with a dead-white, angular flourish; she ends her nest with brown mouldings, which run down, irregularly, from the marginal junction to the bulging middle.  For this purpose, she makes use, for the third time, of a different silk; she now produces silk of a dark hue, varying from russet to black.  The spinnerets distribute the material with a wide longitudinal swing, from pole to pole; and the hind-legs apply it in capricious ribbons.  When this is done, the work is finished.  The Spider moves away with slow strides, without giving a glance at the bag.  The rest does not interest her:  time and the sun will see to it.

She felt her hour at hand and came down from her web.  Near by, in the rank grass, she wove the tabernacle of her offspring and, in so doing, drained her resources.  To resume her hunting-post, to return to her web would be useless to her:  she has not the wherewithal to bind the prey.  Besides, the fine appetite of former days has gone.  Withered and languid, she drags out her existence for a few days and, at last, dies.  This is how things happen in my cages; this is how they must happen in the brushwood.

The Silky Epeira (Epeira sericea, OLIV.) excels the Banded Epeira in the manufacture of big hunting-nets, but she is less gifted in the art of nest-building.  She gives her nest the inelegant form of an obtuse cone.  The opening of this pocket is very wide and is scalloped into lobes by which the edifice is slung.  It is closed with a large lid, half satin, half swan’s-down.  The rest is a stout white fabric, frequently covered with irregular brown streaks.

The difference between the work of the two Epeirae does not extend beyond the wrapper, which is an obtuse cone in the one case and a balloon in the other.  The same internal arrangements prevail behind this frontage:  first, a flossy quilt; next, a little keg in which the eggs are packed.  Though the two Spiders build the outer wall according to special architectural rules, they both employ the same means as a protection against the cold.

As we see, the egg-bag of the Epeirae, particularly that of the Banded Epeira, is an important and complex work.  Various materials enter into its composition:  white silk, red silk, brown silk; moreover, these materials are worked into dissimilar products:  stout cloth, soft eiderdown, dainty satinette, porous felt.  And all of this comes from the same workshop that weaves the hunting-net, warps the zigzag ribbon-band and casts an entangling shroud over the prey.
