height, is about 100 feet, and it can be had to square up 
to 30 inches. This wood is of a colour resembling 
cedar, and is used for planking boats, in the construction 
of railway carriages, and for many other purposes where 
a light and strong wood is required. Determa is also 
used for the masts and spars of vessels ; the largest spars 
procurable in the colony for these purposes are of this 
wood, from 70 to go feet long, and 14 inches in diameter 
at the smallest end. A log of this timber 42 inches 
square has been seen. 
Kabukalli is plentiful all over the colony, and thrives 
best in loose sandy soil. It is one of our tallest forest 
trees, and grows very straight ; its average height is 
about 120 feet, and it can be had to square up to 
30 inches free of sap. Kabukalli is used in boat build- 
ing, and for timbers is little inferior to mora. This wood 
has a very unpleasant smell, and is disliked by worms. 
The Indians living in the wet savannahs, or where the 
rivers are unshaded by trees, prefer canoes made of this 
wood to any other, as it does not split when exposed 
to the sun. A gelatinous substance forms on the stump 
from which a kabukalli tree has been cut down ; it has a 
disagreeable smell, and never hardens. 
TATABOO grows in sandy soil, and is not a very com- 
mon wood. The average height of these trees is about 
80 feet. The wood is dark-coloured, heavy and hard, 
and well adapted for mill-bed timber ; it is also used 
in boat-building, house framing, &c. Tataboo may be 
squared to 22 inches. 
MAMOORI-BALLI is plentiful in Essequibo, and grows 
best in sandy soil. The average height is about 70
