remains were overlooked. 
Texas.—The River Basin Surveys continued to operate throughout 
the year from the base and headquarters supplied by the Department 
of Anthropology at the University of Texas, Austin, Tex. Sur- 
veys were begun and carried to completion in five Corps of Engineers 
reservoirs. 
Robert L. Stephenson, archeologist, left Austin at the beginning of 
the fiscal year and went to Fort Worth where he conferred with the 
Engineer in Charge, Fort Worth Suboflice, Corps of Engineers, 
preparatory to starting surveys of four reservoir basins on the upper 
branches of the Trinity River. 
During July he completed investigations at the Benbrook Reservoir 
on the Clear Fork of the Trinity River in Tarrant County and at the 
Grapevine Reservoir on Denton Creek in Tarrant and Denton Coun- 
ties. No sites were found in the Benbrook basin and only 10, none 
of which require further investigation, were noted at Grapevine. In 
addition he made a 2-day reconnaissance in the areas of the Lavon 
Reservoir on the East Fork of the Trinity River and Garza-Little 
Elm Reservoir on the Elm Fork of the same stream. On the latter 
trip R. K. Harris, Rex Housewright, and Lester Wilson, of the Dallas 
Archeological Society, took him to sites that they had previously 
located in the two areas. 
On August 1, Mr. Stephenson accompanied Drs. Gustav A. Cooper 
and A. R. Loeblich, Jr., of the United States National Museum, and 
Robert Stark of Grapevine, Tex., to the vicinity of Bridgeport, 
Wise County, to collect invertebrate fossils. He also visited the 
Whitney Reservoir on the Brazos River, Hill County, and collected 
mollusks, needed to check previous identifications, from several archeo- 
logical sites. From there he went to the Texarkana Reservoir on the 
Sulphur River, Bowie County, for the purpose of gathering informa- 
tion regarding the dates of construction and of determining the neces- 
sary time and extent of a survey for that basin. During the month 
he also completed an intensive survey of the Garza—Little Elm basin 
where he noted 27 sites, 7 of which were recommended for further 
examination, and started investigations at the Lavon project. The 
latter continued until September 17 and during the progress of the 
work he made test excavations at two sites. The survey located 25 
sites, of which 8 have been recommended for more intensive investiga- 
tions. Both in the excavations and the survey he was greatly assisted 
by the members of the Dallas Archeological Society and on September 
10 spoke before a meeting of that organization. On September 18 he 
started a survey of the San Angelo Reservoir area on the North Concho
