varieties of common beans are found as well as lima and 
runner beans. In addition to these plants, Manihot dul- 
cis, amaranth, chili, Panzewm, sunflower, Nicotiana and 
cotton occur. In bulk, these species represent almost 
half the plant material found; in terms of food value, 
however, they represent a much larger proportion. Arch- 
aeologically, this phase is represented by a mass of ma- 
terial and traits. Only a bare minimum of the diagnostic 
artifacts will be mentioned. These include corner-notched 
arrow and dart points, serrated corner-notched points, 
engraved red, brown, and black pottery, packboards with 
net centers and wooden rims, complicated woven mats 
and cotton cloth, platform pipes and cane cigarettes, 
mold-made figurines, polished celts, circular pyramids 
and house platforms, as well as many other stone archi- 
tectural features. 
Though the sedentary agricultural San Lorenzo is ob- 
viously derived from Palmillas, there seems to be a short 
gap in the sequence and a degeneration in culture and 
agriculture. While all the kinds of cucurbits and beans 
appear, there is less variability. There are also only one 
or two races of corn, no teosinte, and only amaranths, 
peppers, cotton and tobacco. The bow and arrow, and 
a considerable range of arrow-point types appear; the 
pottery is crude — burnished, brushed and corrugated 
ware; the mats are decorated with colors; split-stitch 
bundle foundation baskets are plain; decorated cotton 
double-cloth occurs, and a number of small crude end- 
scrapers. 
The San Antonio culture represents an even further 
degeneration, though the people of this phase seem to 
have been sedentary agriculturists living in ‘‘ranchos.”’ 
Corn was apparently of a single race; there are only four 
kinds of beans. Cucurbits (Cucurbita Pepo and C. mos- 
chata), gourds, cotton and tobacco still occur. Many of
