Ficure 25.—Sketch map of N-19: Kumaka, a habitation site of the Mabaruma Phase. 
Although sherds were found throughout the 70- by 17-meter site 
area, the major portion of the surface collection comes from the 
southwestern sector where there was no grass cover. A few scattered 
sherds were found in the flat between dry land and the creek bed, in 
the region traversed to reach the water source at low tide (fig. 25). 
A small strata cut, 1- by 1 meter, was excavated in 15 cm. levels about 
halfway between the road and the upper edge of the site, where recent 
disturbance seemed minimal. The following conditions were ob- 
served : 
Level 0-15 cm__ Soil medium gray with numerous lateritic concretions to 
a depth of 12 cm., changing to light reddish-brown loam 
with more abundant concretions at 12-15 cm. Sherds 
abundant in upper 10-12 cm., absent below. 
Level 15-80 cm__ Sterile, reddish-brown soil color continues to 25 em., 
where soil changes to orange-red clay (the soil profile 
in this excavation is the same as that revealed in the 
road cut). 
N—20 : KOBERIMO HILL (KOBARIMA, KOBERINO, KOBARINO) 
Koberimo Creek skirts the south edge of Koberimo Hill before 
flowing out into the swamp to empty into the Aruka River (figs. 4, 
22). N-20 is on a nearly level shelf at the base of the hill next to the 
creek, The bank rises rather steeply to a height of 4 meters above the 
swamp level before leveling off, and the site begins about on the 4-meter 
contour. The refuse deposit extends 75 meters along the creek and 
25 meters inward. The surface was free of undergrowth and the 
site limits were easily definable by the contrast between the black 
soil of the habitation refuse and the reddish-brown sterile soil of
