small primitive or green ears had been masticated and 
digested, leaving no cob or kernel remains in the refuse. 
Opuntia and runner beans also served as food. Distinc- 
tive artifacts for this complex are Fuegian and _ full- 
turned coiled nets, three-over-three twilled baskets, 
twilled and plaited mats, large triangular and leaf-shaped 
atlatl dart points, interlocking loop-coiled baskets, 
gouges, antler hammers, and a wide variety of larger 
scrapers (planes) and choppers. There likewise occurred 
more general traits, such as different kinds of string and 
knots, mats, bone awls, wooden wedges, dart points, bi- 
facial knives, shell beads, mortars and gourd containers. 
The Flacco Phase developed directly from the 
Ocampo. The people of this phase were also semi-nomadic 
food-gatherers, but they depended more on incipient agri- 
culture than on hunting or trapping of game. Squash, 
gourds, corn, chili pepper, two kinds of common beans 
(found in the feces), Panicum, amaranths, and runner 
beans made up apparently about twenty percent of their 
diet. Long contracting-stem and indented-base points, 
mullers and mortars, spokeshavers, Fuegian baskets, 
spring traps and snares, twilled baskets, simple coiled 
bags and elongate chisels are diagnostic traits. Though 
most of the heavy stone scrapers and choppers of Ocampo 
are not present, the more general traits continue to occur. 
With the development of the semi-sedentary Guerra 
peoples, there occurred a fundamental shift in diet. 
While they still collected a vast amount of wild plants, 
agriculture furnished most of the energy-producing 
foods. The most prevalent remains are corn cobs (Bat 
Cave race). In addition, gourds, several varieties of 
pumpkin, squashes (Cucurbita moschata), peppers, com- 
mon beans, amaranths, Panicum and cotton occur. The 
cave occupations, and also the survey, indicate the possi- 
bility that these people occupied small villages. Split-
