There is another species of a
large-sized spider who spins a web of about two and a half feet
in diameter. This is composed of a strong, yellow, silky fibre,
and so powerful is the texture that a moderate-sized walking-cane
thrown into the web will be retained by it. This spider is about
two inches long, the color black, with a large yellow spot upon
the back, and the body nearly free from hair.
Some years ago an experiment was made in France of substituting
the thread of the spider for the silk of the silkworm: several
pairs of stockings and various articles were manufactured with
tolerable success in this new material, but the fibre was
generally considered as too fragile.
A sample of such thread as is spun by the spider described could
not have failed to produce the desired result, as its strength is
so great that it can be wound upon a card without the slightest
care required in the operation. The texture is far more silky
than the fibre commonly produced by spiders, which has more
generally the character of cotton than of silk.
Should this ever be experimented on, a question might arise of
much interest to entomologists, whether a difference in the food
of the spider would affect the quality of the thread, as is well
known to be the case with the common silkworm.
