Capio Chico Chileno 
Twenty of the oldest cobs are considered to be related 
to this modern race; their characteristics are set forth in 
Table 1. All of the cobs represented in this table came 
from the test excavation described above. Layer pro- 
venience is represented by the last number in the code, 
except that layer 2 is represented by two code numbers, 
2 and 7. There is no clear relationship between the depth 
of the layer and the characteristics of the cobs. Within 
each layer the cobs are arranged in order of their lengths, 
for identification purposes. 
We call particular attention to the last cob listed in 
Table 1. This was very small with a length of 2.6 cm., 
a diameter of 1.6 cm., and 12 kernel rows. The senior
