SIXTY-SIXTH ANNUAL REPORT 29 



Kiver in Tom Greene County, which was finished on October 10. 

 Only 13 small sites were located there, and as similar material is avail- 

 able elsewhere no fm-ther work was recommended for the basin. 



Except for several short trips, Mr. Stephenson spent the remainder 

 of the fiscal year at the headquarters in Austin analyzing the material 

 collected and preparing reports on the summer's surveys. He went to 

 Lincoln, Nebr., in November for the purpose of studying the field 

 and laboratory methods being used by the Missouri Basin group and 

 while there attended sessions of the Sixth Conference for Plains 

 Archeology and was appointed to the Committee on Archeological 

 Nomenclature. From January 2 to 7, he revisited the upper Trinity 

 Eiver area to investigate reports of additional material having been 

 found there. Papers prepared by Stephenson during the months in 

 the laboratory are: "Archeological Survey of McGee Bend Reservoir,'' 

 which was published in volume 19 of the Bulletin of the Texas Archeo- 

 logical and Paleontological Society; "Archeological Survey of the 

 La von and Garza-Little Elm Reservoirs," to be published in volume 

 20 of the same journal; "A Note on Some Large Pits in Certain Sites 

 near Dallas, Texas," printed in American Antiquity, vol. 15, No. 1; 

 a revision of his earlier report on the Whitney Reservoir which was 

 mimeographed and distributed by the Washington office in April; 

 and preliminary appraisals on the Benbrook, Grapevine, Garza-Little 

 Elm, and San Angelo surveys. He also wrote a summary statement 

 covering the results of the River Basin Surveys from their inception 

 in 1947 to June 30, 1949, and prepared a summary and table of the 

 culture sequences and their relationships in the Texas area as they 

 had been worked out up to that date. 



Results of the year's investigations established a number of facts. 

 In the survey of the Garza-Little Elm basin it was found that the 

 remains include key sites for the determination of the cultural 

 sequences in the area east of that known to have been inhabited by 

 groups classified as the Henrietta Focus and west of the known 

 Caddoan area. Similar sites have not been observed elsewhere. Very 

 httle is known of the cultural sequences involved in the area drained 

 by the three forks of the Trinity River. The eight sites in the Lavon 

 basin recommended for more intensive examination are believed to 

 hold the answer to the problem of developments in the western border 

 of the Caddo area. At least one new culture remains to be defined 

 and described from the excavation of those sites. Furthermore, the 

 material from them should shed much light on the interrelation 

 between the cultures represented there and those to the east and west. 



Cooperating institutions. — Numerous State and local institutions 

 cooperated with the River Basin Surveys throughout the year and 

 made a definite contribution to the progress of the program. The
