While invocation has produced mrny
substances which in part replace wood
and other organic materials. the fact,
remains that man is today almost us
dependent for his comfort and very
life on the vegetable world as were his
ancestors in more primitive times. The
anatOmists have had long disputes as
to mans place in the scale Of food con-
sumption, whether he is properly om-
Mivorous or not. Whether carnivorous
or vegetarian. his food derives its ulti-
mate origin in the wonderful chemical
decomposition and synthesis effected
by the vegetable Kingdom. The highest
triumphs of synthetic chemistry lave
not yet succeeded in producing his food
from the chemical elements. The pro-
duction of self-supporting aquaria, con-
sisting Of tanks OF water In which
plant life and fish life are so exactly
balanced that there is Il miniature self
supporting world within tile four glass

amusement with many. On our globe
we see a singular thing in the relations
of the animal and vegetable kingdoms.
Unfortunately, q is not content with
DISCRIMINATING wild animals; he is not
satisfied with utilizing for himself all
vegetable nature; but he exterminates
most recklessly the forests whose
leaves are taking care of his own vitiat-
ed respiratory products.
The earth contains plant and animal
life. each One taking care of the pro-
ducts Of the life of the other kind. The
animals expires carbon dioxide gas
the product of the combination of oxy-
gen of the air with the carbon of. the
body. In a painless globe this gas
would constantly increase in the at
mosphere. to the eventual deterioration
of the air; but the plant life disposes
of this product; separates the carbon
from the oxygen. and still more o
derful. effects one of the most difficult
| of syntheses, and unites the carbon
with hydrogen. producing vegetable
substance Of different kinds. The puri-
ficatiOn of the air by plants. owing to
the enormous volume of the atmOs-
phere and its relatively slow contain
nation. Is of secondary Importance to
the production of plant substance. On
the products of vegetation man de-
ponds for nearly everything, for food,
raiment and heat. Not content with
reckless dcforestation. he draws upon
the accumulated stores of the preced-
ing geological eras, and In burning coal,

ages.
Plants by their vital power effect
two specially difficult chemical actions
the decomposition of carbon lioXide
gas. and then combine the separated
carbon with hydrogen. Absolutely no
practical way of doing these things
has been as vet found. by man. 1t is
only by a laboratory experiment that
either of these two reactions is carried
out. 1t may be said that every steam
engine depends for Its fuel on decOm.

In the matter Of food man is still more
dependent on the vegetable world.
Very few artifically produced food
products. have ever been made, and
these few may have their origin traced
to some vegetable product. The glu-
cose factories use n product of vegeta-
!! ton as the base of their operations.

continue to depend upon the soil for
his very life. He may selfishly feel
