the early inhabitants of northern
Europe used bone implements instead
of stone as their contemporaries die
in southern Europe.

The new 200-ineh telescope lens will
be in operation some time during the
next year. 1t will be located If
southern California on one of the
high mountain peaks. It will give the
astronomers an opportunity to further
the research in astronomy. Such a
telescope will magnify $4,000 dia-
meters.

Under the Biological Department at
Washington, D. c. 10000 leg bands
have been placed on migratory birds
in order to study the habits of these
birds. Over 5000 bands have been
reported recovered by hunters and
trappers. 1t was found that ducks
+, banded in the western portion of the
United States are recovered in the
western portion, just as birds banded
in the East are recovered in the east
ern areas of the continent. Very few
bands show intermingling of eastern
and western ducks.
Llamas differ from camels in being
smaller and having no humps. The
llama had its development in South
America while the camel developed
IN South Africa. The ancestors to
these two animals had their origin in
North America. One migrated to
South America via the Panama reg
ion while the camel migrated over
the land bridge of prehistoric times
to Europe and Asia. Glacial and eli
matte conditions drove these animals
from their northern ranges to the
south.

Psychologists, the scientists who
study prehistoric life by the fossil re-
mains found in the rocks, have col
lected 20 varieties of the early horse.
The specimens show all stages of
evolutionary development from the
small Eohippus, an animal ~ inches
high with four and five toes to the
present day horse with its one toe.
The early horse was capable of
adapting itself to various conditions.
1t could live in the mountains, on the
range or in the swamps. It had a
large brain cavity compared with
other prehistoric animals.

OF Invertebrates, Fish, Amphibians,
reptiles, Mammals and the Age Of
Man.

The layers of the crust of the earth
were first named by biologists ac-
cording to the geographical location
OF the discovery. Another division
Of classification is based upon the
life that existed during the period in
which the layer was formed. 1t was
apparent, by the fossil discoveries
that definite sequence existed. The
earliest or oldest layers contained the
single celled organisms and the later
layers or strata contained the more
complicated organisms.
Each step in the development cor
responding to definite geologic
period of the earth. Biology tells us
that the first cell life started in the
waters of the earth. First was pro-
duced the primitive or simple forms.
as unicellular and inverte- !
brates. Some Of these still exist to-
day. The jelly-fishes, star-fish, sea-
urchins, oysters, snails, squids, lob
sters and crabs.
Then followed the Vertebrates,
these that had a backbone or verte-
brae. The fish was the first, then
followed the Amphibian. Those that
ilved IN water or on land like our
present day frog and salamander.
After these we had the Reptiles,
waking, swimming and flying varie-
tles. The walking or land reptiles at
tanned length of 10 to 800 feet while
the swimming reptiles grew to a
length of from so to 70 feet. The
flying variety ranged from the size
