/ 
Dr. Charles S. Schuchert, emeritus 
professor of paleontology at Yale 
university, noted geologist and strat- 
igrspher and foremost authority on 
the paleogeography of North ^Amer- 
ica, addressed a large gathering of 
geoligists and men interested in the 
oil industry here Monday night at a 
meeting of the Shreveport Geograph- 
ical society. 
Doctor Schurchert outlined the 
trend on modern thought relating to 
the origin of petroleum deposits. He 
emphasized the importance of micro- 
organisms as a source of oil. 
Doctor Schurchert traced the de- 
velopment of the paleogeography of 
North America from earliest times 
to the present, emphasizing Llanoris, 
a huge ancient land mass which up 
to Cretaceous times, he said, occu- 
pied a large part of Mississippi, Lou- 
isiana and Texas. He pointed out 
how the denudation of this great 
mountain region supplied the great 
■thicknesses of materials that now 
make up the Ouachita and Arbuckle 
mountains of Oklahoma and Arkan- 
sas. He brought out the probable 77 
origin and age of the Louisiana salt 
deposits and the influence of Llan- 
iiris upon the structural features now 
found in the oil fields of Arkansas, 
Louisiana and Texas. 
Dr. Schurchert has consented to 
deliver another address tonight in 
which he will discuss the fallacies 
of Wegener's continental displace- 
ment theory. This theory which has 
recently been widely discussed by 
geologists, postulates the westward 
migration of the continents whereby 
the Americas have been separated 
from Europe and Africa and drifted 
westward to their present positions. 
In this theory Wegener endeavors 
to explain the origin of the Rochy 
mountains and the Andes mountains 
tnd many other features of the 
earth’s geologic history. 
This meeting will be held tonight 
at 7:30 o’clock in the* city hall.
