FROM 5 EXPEDITIONS
~ Assoclated Pressl

CHICAGO, Aug. Reports Of IN
teresting scientific discoveries are be-
ginning 10 come in from five expedi.
tions which have been sent out this
year by the Field Museum of Natural
History, to ferret out secrets OF the
worlds past that are buried in rocks,
or hidden away in spots that are al
most inaccessible. A sixth expedition
will soon start Most of this work is
to be done in portions of South Amer
lea where there has been but little
scientific exploration
A geological expedition under the
direction of DR.. Oliver c. Harrington
is now proceeding into the interior of
Brazil toward the upper reaches OF
the Amazon TO obtain a series of min
erals relating to the diamond in an
endeavor to trace, if possible. the pri-
mary rocks which are the source of
the diamonds The diamonds of Bra
I'll differ in their occurrence FROM
those in other parts of the world in
being found in highly quartzose or
granite rocks.
Primary Source
In all other important diamond bear
| ing rock localities the primary source
of the diamond is rock composed mag
nesian silicates and containing no free
| quartz 1t is also hoped to procure
| full series of the rare Brazilian dia-
mond accompanying materials which
/ are not found elsewhere.
| Two botanical expeditions and one
geological expedition have been in
the field for number of months. One
of the botanical expeditions left the
United States early in March. under
! the guidance OF DR.. D. z. Dahlgren, fo-,
British Guiana to collect specimens
| for plant reproduction and economic
| botany.
A botanical and geological expedi-
J ton landed at Callac, Peru, the latter
/ part of April and after a short stay
in the coastal regions crossed the
Andes to work on the eastern slopes
until early fall, when they will starr
down the tributaries of the Amazon
and thence down the Amazon to the
Atlantic.
Places To Be Seen
This combined expedition VIII en-
i counter many varied geographic and
climatic conditions. At times they
will be in lands where both plant and
animal life is exceedingly sparse and
: at other times they will be in the
| dense jungles of the upper Amazon.
Again they will work in regions near
: the tops of the mountains where eli
matte conditions will be those of the
: extreme southern end of the continent
and later they will encounter the tor
rid climate of the equatorial regions
Il when they reach the jungles. Some
: of the country they will explore con
5 tains what are virtually land islands
for they are completely surrounded
. by high mountains, and contain ami
nal and plant life little known tc
the outer world
u Many rare and interesting speci
! mems are being gathered by these ex
Il petitions, which are under the leader
ship of Edmund Heller, noted Soutf
!. American and African explorer who
:. was with Theodore Roosevelt on hi
! expedition into Africa. Accompany
! ing Mr.. Heller are John T. thinner
