tree. Most of the sherds were concentrated in an area 15 meters in 
diameter in the north half of the site, where the soil color was darkest. 
Cut 1, 1 by 1 meter, was excavated in the north half of the area of 
greatest refuse concentration. Level 0-8 cm. produced abundant 
sherds and roots in dark-gray soil containing scattered lateritic concre- 
tions. Level 8 to 16 cm. continued the same conditions. In level 16-24 
cm., sherds were fewer and concretions more numerous. The soil be- 
came lighter in color and sterile at 26 cm., changing to light-tan sandy 
clay at 40 cm. 
E-15: MASHUKROTHO 
A short distance below E-7 (fig. 79), the right bank of the Esse- 
quibo River rises steeply for 6 meters forming a large nearly level area 
not subject to flooding. Although trees reached 75 cm. in diameter, 
the Indians recognized the vegetation as secondary growth over an 
area some 200 meters long by 150 meters deep. Sherds were encoun- 
tered in only one place, which was slightly higher than the rest of the 
area and 30 meters from the shore. A 1- by 1-meter excavation pro- 
duced sherds only between 8 and 16 cm. below the surface. The soil 
was light gray and sandy in the occupation layer, becoming a little 
lighter in color below.
