One of tha beat known la
the bladderwort. a floating
aquatic plant, which, having;
no roots, la usually found la '
quiet pools from which thera
la no danger of Ita being
washed away. Tha trapa are
mall globular atructurea
that capture Inseot larvae or
very minute Insects.
Only ona apeclea of tha
pitcher plant la .found north
of Virginia. This Is tha pur
ple variety, and la located In
awarepe and bogs. The stalk
la short, and the leaves ara
not lifted above the surface,
altheugh at blooming time
the flowers ara elevated a,
" ' foot or mora. " - -
- Further south ' ara found varletiea of tha pitcher '
'. plant holding Its leaves two or three feet high. The eupa
are provided with a kind of lid, or trap dodr, wMofc
. - clones during the heavy, seml-troploal rolni a, wise pro-
. vision of nature to provide against tha weight of water ,
breaking down the atalk.
StlU another protective arrangement marks th4 Calk
. fomla pitcher, tha ton of which ia covered with a hood
; that, bending over, shelters tha Interior. On tha aide of
' , the hood opposite the mouth of the trap ara a number of
- . apots. which some botanlsta regard ae fale wisdom.
' - The voraclowmeaa of the pitcher planta found Is
the tropical forests of the East Indian Islands exceeda
. that of their American relatrves. Their pendant cups
are provided with llils or covers, which hot only close
.; over the struggling v let I ma caught within, but keep out
'. i avery drop of rainwater. i - ,
v. t These eupa, too, are-partly -filled -with water, but -water
which they supply themselves.. - A curious thing
about tha fluid Is that ft contains a digestive element
- resembling the pancreatic Juice of the human stomach.
More effective In aiding capture la thla fluid than th
ordinary rainwater found in moat varletiea of the pitcher '

.A suoetance known aa aaerln Is found in the eupa
! of theae Kast Indian insect traps. Its peculiarity la that ''
' , It causea every pert of a hairy surface to become wet
- : almost ae soon as tha fly falls Into the tank, which moan
"", quick and certain death to the Insect.
. "' Turning from a atudy of planta that trap and devour
- Insects for a living, one finds the opposite of nature '
, -.. eccentricities In animal life that blossoms as a flower.
A curious manifestation of this freak la found In tha
ea anemone, a little creature which bear a kind of fam
ily relationship to the coral polyp.
When closed the anemone somewhat rembles a di
minutive doughnut, considerably smaller at the top than '
. at the hottnm. At times this top opens, and tho little -'
creature puts out a number of long pretty pink or yel
low fingers, ilka tha white petals of a daisy an animal .
in bloom. ...,.
These fingers are the tongues' of tha anemone, with
which It gathers Its food. If you plsce a- bit of meat,.
. - fish or some other palatable food on one side of the
- tongues, it will close about the morsel and convey It
Inward to the mouth. , .
A bl wsomlng creature which hue added to the wealth '
- and beauty of the world la the coral polyp. 'The coral
' young remain clinging to the parent body In turn, pro
dure young of their own, which remain; and so the pro-
cese continues. Bach exudes the homy secretion, or lima
C articles, that make the mineral known as coral; piling r -tyer
