trade pottery so that it cannot with certainty be identified with the 
“Koriabo Hill” visited by Verrill (1918 a, p. 17). The fact that he 
specifies “no shells” suggests he must not be referring to N-4. 
A small stratigraphic cut 2 by 1 meters, controlled in 8 cm. levels, 
was placed in the center of the sherd area. It had the following 
characteristics: 
Level 0-8 cm___. Disturbed by modern tomato cultivation; soil a black loam 
mixed with large quantities of natural float quartz, iron 
concretions, granite fragments, and large hunks of mod- 
ern charcoal from recent slash and burn clearing. 
Sherds fairly abundant. 
Level 8-16 em__. Same conditions. 
Level 16-24 em_. Rocks more abundant, sherds sparse. 
Level 24-32 em... Soil continues dark gray until 32 em., where it changes to 
light gray. Sherds sparse; small, angular, granite frag- 
ments becoming more common. 
Level 32-65 cm_. Sterile; from 32-45 ecm. the soil is light gray; 45-55 
cm., orange gray; below 65 cm. very sandy clay. 
N-12: HOSORORO HILL 
This site is on the summit of a hill in a chain southwest of the one 
occupied by N-1 (figs. 4, 22) and, being nearly as accessible, it has 
been visited repeatedly. It is mentioned by Walter FE. Roth (MS.), 
Verrill (1918 a, p. 16), and Osgood (1946, p. 33). As Verrill 
notes, there are two sites (fig. 21): an Alaka Phase shell midden at 
the base of the hill, which we have desigated as N-11: Hosororo Creek, 
and a Mabaruma Phase site high up on the slope, which we have 
designated as N-12: Hosororo Hill. <A collection of artifacts from 
“Hosororo” is in the British Guiana Museum. 
Hosororo (Ossorero, Issororo) Hill rises on the left bank of the 
Aruka River to a height of some 90 meters. The base of the hill is 
separated from the river by a strip of mangrove swamp, now drained 
for agriculture (pl. 9,5). The slope facing the river rises in a series 
of broad steps or shelves, whose nearly flat or gently sloping surfaces 
are separated by narrower areas of steeper rise (fig. 21). The largest 
shelf is between the 50- and 60-meter contours, and its size and relative 
levelness make the area ideal for habitation. A further advantage 
is Hosororo Creek, a small stream with clear, fresh water, that plunges 
down a series of small falls at the south edge of the shelf. Behind, 
the hill rises some 30 meters higher to its summit. 
The whole hill was originally covered with trees. In 1917, part of 
the summit had been cleared for a rubber plantation (Verrill, 1918 a, 
p. 16). In 1958, the upper shelf was occupied by the District Govern- 
ment Agricultural Station, consisting of a house and a fenced ex- 
perimental garden (fig. 21). The hillside had been cleared of the
