Avansand ARCHEOLOGY IN BRITISH GUIANA 127 
Level 16-24 em__ Sandy soil still light gray; quartz spalls common, sherds 
sparse. 
Level 24-32 cm_. Small hunks of orange clay scattered on the sandy soil; 
a few sherds still present in the south part of the cut. 
Level 32-60 em_-_ Sterile. Clay mixed with sand up to 40 cm.; then bright- 
orange clay containing iron concretions. 
N-5: BAMBOO HILL 
N-5 occupies a knoll on the right bank of the headwaters of Ko- 
riabo Creek, which flows into the right bank of Barima River just 
above the Koriabo Government Rest House (fig. 4). The area is 
overgrown with clumps of tall, large cane and locally known as Bam- 
boo Hill. The headwaters of Koriabo Creek are more accurately 
described as a swamp, with the land rising on the east side to as much 
as 5 meters above the water level. Heavy forest surrounds the site 
area. Sherds occur from the water’s edge to the 4-meter contour 
line and there is some evidence that the front edge of the site has 
been washed away. The habitation area is approximately oval, 36 
meters in an east-west direction inward from the creek bank by 50 
meters along the bank in a north-south direction. Sherds were over- 
lain in most places by the root mass of the cane. In addition to vari- 
ous tests, a strata cut 2 by 1 meters, controlled in 8-cm, levels, was 
placed in the approximate center of the sherd area. The following 
conditions were observed : 
Level 0-8 cm_-_-. Dense root mass, 
Level 8-16 em___ Medium-gray sandy loam with many roots, a few cracked 
quartz fragments and sherds. 
Level 16-24 em__ Soil lighter colored than in previous levels, containing 
decomposing fragments of granite; sherds fairly 
abundant. 
Level 24-32 em__ Sandy loam streaked with dark gray from ash, with occa- 
sional red globs of burnt sandy clay; sherds. 
Level 32-60 cm__ Sterile light-gray loam with occasional pockets of fire- 
burnt bright-orange, sandy clay down to 42 cm. Below 
this level, the sandy clay becomes bright orange. 
N-7: WARAPOCO MISSION SITE 
Warapoco Creek drains into the Jeft bank of the Waini River just 
upriver from the government post of Baramanni (fig. 4). Near the 
upper reaches of the creek, but not quite to the headwaters, is a high 
right bank that contains many large granite outcrops. The steep 
slope rises in three distinct terraces from the water’s edge to the top 
of the hill at the 8-meter contour line (pl. 31, a). Warapoco school, 
church, and teacher’s house are on the uppermost level, with houses 
scattered down the slope. Large granite outcrops are abundant all 
over the area, in between the houses and along the path. Some of the
