The Many Uses to which Its Singular

Spiders form good subjects for rainy
day study, and two hours spent in
neglected garnet watching these clever
little beings will often arouse such in
terest that we shall be glad to devote
many days Of sunshine to observing
those species which hunt ana build and
live In the open fields. There is no in

legs, and as spider has eight he 10

of butterflies, beetles and wasps and
finds himself in a strange assemblage.
Even to his nearest relatives he bears
little resemblance, for when we real
ize that scorpions and horseshoe crabs
must call him cousin we perceive that
his is indeed an aberrant bough on the
tree Of creation. N
Nature has provided spiders with an
organ filled always with liquid. which
on being exposed to the air hardens
and can be drawn out into the slender
threads which we know as cobweb

"A list Of all the uses Of cobwebs

the most familiar is the snare set for

spiral which is SO elastic, so ethereal,
and yet strong enough to entangle a
good sized insect How knowing seems

he spins strong cable from the center
Of the web to the entrance of his
watcntower. Then, when trembling
Of his aerial spans warns him OF a cap
ture, how eagerly he seizes his master
cable and jerks away on it, thus vibrat-
ing the whole structure and making
more certain the confusion Of his vic
tim.
Those spiders which leap upon their
prey instead Of setting snares for it
lave still use for their threads of
life, throwing out cable as they leap
to break their fall If they miss their
foothold. What strange use Of the
cobweb Is that Of the little flying spi-;
ders! Up they run to the top Of q

out several threads, which lengthen

them, and away goes the wingless aero

A most fascinating tale would unfold
could we discover all the uses of cob,

through with it. Certain it is that our

webs to fasten together the plant down
and lichens which compose her dainty
nest. s

bubble Of air, upon which he draws
