136 TIMBER AND TIMBER TREES. [cHaP. 
THE PINGOW TREE ss 
is also found in the island of Borneo, where it is said 
to be plentiful. It is of straight growth and good 
dimensions, and yields timber of from 25 to 40 feet in 
length, and 11 to 18 inches square. 
The wood is of a dark brown colour, hard, heavy, 
tough, rigid, and remarkably strong; it is straight in 
the grain, close in texture, and not difficult to work. 
It is used in Borneo for all the purposes to which the 
Chow is applied, except that, as the tree does not attain 
the same altitude, it will not furnish masts for any but 
the smaller junks. The characteristic properties of the 
Pingow are favourable to its introduction for any 
purpose where great strength is required; and, of the 
sample logs brought to this country in 1860-61 and at 
subsequent dates, the whole were passed either to 
Woolwich Dockyard or to the out-ports, to be employed 
in ship-building.
