a writer has recently distinguished
animals as those which derive their
food from the soil and those which
live on other animals. The fact is, how
ever, that all animal life is supported
directly or indirectly from the soil. The
food OF all animals is vegetation or 9TH
er animals which live on vegetation.
Thus all animal life rests on a vegeta-
bic basis.
Many persons have the idea that the
food of nearly all tile fishes is animal
life found in the sea. This is probably
true of many varieties. but not a few
fishes are vegetarians and there are
many fishes that vary their meat diet
with more or less vegetable food. a
little while ago an English naturalist
who was dissecting Dream found in
its stomach i'll addition to a crab a con-
siderable quantity of two kinds OF sea-
weed though the Dream is reputed TO
live on animal life. Some of the text
books say that the gray mullet, popu-
lar fish in British waters, feeds only on
the animal matter it obtains by strain
ing sand or mud in its mouth. This is
not scientific conclusion. No biologist
Of European university could convince
practical Cornwall fisherman that the
gray mullet does not eat seaweed. He
knows that this is so for he often finds
the ish's stomach full OF seaweed.
There is great deal of vegetable
matter floating around in the sea. Ev-
erybody knows Of the eddy in the At
lantic ocean where the currents whrl
the hundreds Of miles around a great
center, the Sargasso Sea, in which sea-
weeds drift and remain in the quiet
waters within the swirl until they be-
come waterlogged and sink of their en-
ira weight. 1t has been found that the
enormous quantities Of seaweeds. alge
and other vegetation that cover the sur
face Of the Sargasso Sea with vivid
green are mostly torn by the waves
from the shores of Yucatan and other
Gulf OF Mexico coasts and drift for
many hundreds Of miles before they find
lodgment in the Sargasso. Vast guam
titles Of vegetation also drift out to sea
that never reach the currents whirling
around this grass-eovered part Of the
ocean. Thus vegetation from the land
has wide distribution over the sea and
il has been proved that it is relished
by many varieties of fish.
The scientific work of DR.. Nansen in
Arctic waters proves that large popu-
lation OF fish is introduced into the cold
seas from the west, and that the food
supplies to support this vast marine
population come mainly from the east

nourishment to the pelagc animals oil

fnent consists OF microscopic algae, some
of the smallest specimens Of vegetable
life. They are chiefly diatoms which
are found to abound in the superficial
polar water of the Siberian Sea, though
gradually diminishing in quantity west

largely fed upon by various plagic ami
mails. Indeed, without such a constan
conveyance Of nourishing matter Their,
could be no such rich fish and othel

BY the ice in northern waters. They ar,

plants on which the northern fish fee,

OF course, the sea is full OF grea
variety OF food. Fish not only prey upo

other forms OF vegetation, but they ar
also able to vary their diet with worm,
