SECRETARY’S REPORT 83 
River 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 further 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 
River 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 
Lavon 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 
little 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
