ABORIGINAL SITES IN LOUISIANA AND IN ARKANSAS. 9 
Both these gentlemen had been with us in some of our investigations and 
were fully conversant with the nature of our work. Captain Platt subsequently 
commanded our steamer throughout the season. 
Dr. M. G. Miller, this season, accompanied the expedition as anatomist, 
as has been the case in all our previous archeological investigations, and has aided 
in putting this report through the press. 
Mr. 8. G. Weir was present as assistant for the third time and aided the 
expedition in various ways. 
The thanks of the Academy are tendered: Dr. Ales Hrdliéka for his paper 
on the crania discovered by the expedition, which appears at the end of this 
report; Prof. Е. A. Lucas for determination as to bones of lower animals; Dr. H. 
A. Pilsbry for identification of shells; Mr. F. J. Keeley for determination of 
minerals and of rocks; Dr. H. F. Keller for chemical tests; Miss H. N. Wardle for 
aid with the index; and Mr. F. W. Hodge for literary revision of the report. 
The Academy also warmly thanks all owners of properties who so courte- 
ously placed them at its disposal for investigation, and wishes to assure them that 
their kindness is most thoroughly appreciated. 
All sites are described in order ascending streams or lakes, though the in- 
vestigation was not always made in this way. 
ATCHAFALAYA RIVER, LOUISIANA. 
Atchafalaya river, in reality a continuation of Red river, leaves that stream 
eight miles by water from where such waters of Red river as have not been 
diverted by the Atchafalaya, enter the Mississippi. 
The Atchafalaya, after leaving Red river, follows a course southeasterly 
in the main, through the lower eastern part of that portion of the state of Louisi- 
ana that lies west of the Mississippi, and passing through part of the maze of 
lakes, bayous, and waterways found in that region, ultimately enters the Gulf 
of Mexico. In following this course, Atchafalaya river, at Butte La Rose, 
spreads into a swampy region intersected with bayous and lakes, and the name 
of the river temporarily is dropped, Upper Grand river and Grand river being 
usually considered as continuations of the Atchafalaya. The stream, however, 
comes together a few miles above Morgan City, and the name Atchafalaya is 
resumed, continuing on to the Gulf. 
Atchafalaya river (under its various names) was searched in our behalf 
previous to our expedition by Capt. J. S. Raybon and a companion, from its 
junction with Red river to Morgan City, 148 miles by water.’ In addition, 
Only seventeen crania were discovered, this season, in a condition to preserve. Sixteen 
of these came from the mound on Sorrel Bayou, in the Atchafalaya region, Louisiana, and one 
from a mound on Saline river, Arkansas. 
* These eight miles are given the name Old river on some maps. 
* All distances by water, of any importance, given in this report, are measured miles from 
United States Government maps.
