(From New York Herald.)
Arriving here Saturday after lead
ing a scientific expedition for three
years in Mongolia, Roy Chapman
Andrews said yesterday that over
whelming proof had been found thai
reptiles and mammals originated
there and migrated in later ages tC
Europe and America and other parts
of the world.
To obtain this proof was the goa
of the expedition which was or
ganized to test the theory advanced
twenty-three years ago by Prof
Henry Fairfield Osborn, president OF
the American Museum of Natural
History, that the real home of the
great families of land creatures was
north central Asia. He made this
prediction because the dinosaur and
mammal fossils of America and Eu-
rope could not be traced on those
continents back to very early forms.
This meant that they were immi-
grants from Asia and Europe. Prof
Osborn and his associates collected
evidence which convinced them that
the native home of these immigrants
was the Cobb desert and probably
parts of Chinese Tibet and Chinese
Turkestan.
] This brilliant theory has been
| solidly established as a fact said
Mr. Andrews, for we have obtained
| fossils of the ancestors of every form
of dinosaur and mammal life with
the exception of the horse and the
man.
The prediction of Dr. Osborn is
that the sO-called missing link, or the
ancestor of man, and the ancestors
| of the horse will be found in this
same region.
Next season the expedition will
set out to find evidences of the miss
ing link and of the earliest type of
the horse. | am convinced beyond
any shadow of doubt that these re-
mains will eventually be found in
this region. | believe they will be
found during the next five years,
which we hope to devote to this
search, but whether in the near
future or not. they will at some time
be found there All other parts Of
the prediction have been verified, and
so will this part.

borated brilliant deductions by
American scientists, as against diff

Europe. The party found, he said,
the richest fossil field in the world,
where, according to warnings from
all sides, no fossils would ever be
found. The expedition was financed
by New York men and women and
carried out by the American Museum
of Natural History in cooperation
with the Asia Magazine, by whose
permission Mr. Andrews was able to
tell the story to tie general public
Remains of man and of the horse
might have been found during the
present year, but the expedition hap
pened to strike such rich fossil de-
pOsits OF an earlier age that they
concentrated on these, leaving the
search for the missing link and the
early five toed specimen of the horse
to subsequent seasons.
''The reason animal and rept6fe life
developed and spread from Asia to
the rest of the world is now thor
oughly established geologicalIy said
Mr.. Andrews.
Ten million years or more Tgo at
the beginning of the reptile age,
Mongolia and probably Chinese
Turkestau and Chinese Tibet was a
fine upland with open savannah
country, probably more or less for
ested, with an invigoraCing climate.
Europe and America then were
practically at the Level of the sea,
almost like two RATS tied to a wharf.
This magnificent development of life
was able to take place here I'm Asia
and it spread out to Europe and
America as those continents emerged
from the sea-
From 100000 years ago to
5 1000, 900 years ago, according to the
scientists of the expedition, Asia was
hermit continent populated with
land reptiles, or the, plae0ntologicaA
Garden of Eden Europe ana
America rose at about this time and
formed land connection with Asla,
and at aboue this period or a little
later warm blood developed and
mammals began to appear.
THE date of the beginning of the
great reptile period is about t0,
! 600, 900 years ago." said Mr. An
drews. "The beginning of the, age
OF mammals is about 100000 FEARS
ago. Prof. Osborn believes that the
early ancestors of man began to
emerge about 2,000,0 900 years ago.
eve have only worked, so Tar, in
the early part of the age of mann
mails. We have, however, exposed
great miocene and pilocene forma-
tions which were deposited within
the time in which the early ancestors
of man are believed to have emerged.
I'VE will attack these formations
next season with entire confidence
