heavy, and close-grained wood with a white sap, very- 
durable, especially under ground, but splits if exposed 
to the sun. It is probably the best wood procurable in 
the colony for foundations. Its average height is about 
60 feet, and it will square 10 inches. 
BROWN Siruaballi grows to a large size, and is used, 
like other siruaballis, for boat-building, for which purpose 
they seem specially adapted. It attains an average 
height of 90 feet, and can often be squared to 36 inches. 
OOLOO grows plentifully in loose sandy soil. The 
wood has a strong aromatic scent, is of the colour of 
pale cedar, and should be useful for drawers and shelves 
of wardrobes. Its average height is about 90 feet, and 
it can be squared to from 16 to 18 inches. 
HlAWA [Idea heptaphylla, Aubl.) grows plentifully 
in Essequibo in loose sandy soil ; its wood is little used, 
as it decays rapidly on exposure to the weather. Like 
ooloo, it has a strong aromatic scent, is light, and should 
be useful for drawers and wardrobe shelves. This tree 
produces the gum known as hiawa, or resin of conima, 
which is burnt as incense. The average height is about 
50 feet, and it will square 10 inches. 
Kurana or Red Cedar {Idea altissima, Aubl!) grows 
to a large size and is plentiful in some localities, espe- 
cially on the Waini River ; it is also found on the Cuyuni 
and Corentyn, and on the upper part of the Pomeroon ; 
it grows generally in low situations in clay soil. Red 
cedar is a most serviceable and valuable wood, and its 
uses are too well known to require description. The 
tree averages 100 feet in height, and is sometimes 38 or 
40 inches in diameter.
