Wood very haxd and heavy, close-grained, yellowish-brown. Like 
yacal and mangachapuy, it darkens characteristically on exposure to the 
air. Pith-rays of two sorts, moderately broad and very fine. Pores 
small or very small, clear and unbordered. Eesin very scanty, often 
difficult to see at all. Wood durable; used for construction work.

This is the best member of this group in the Federated Malay States 
and Straits Settlements. It is very much the same as yacal, but may be 
distinguished from that wood by the fact that the tangential section 
always shows distinct parallel transverse lines (ripple marks). The 
wood is used for railroad ties, telephone and telegraph poles, bridges and 
construction work. It is very durable and a very satisfactory wood to 
work, It is produced by different species of the genus Balanocarpus. 
YACAL. Plate XXVII, fig. 67. 
Yacal (Phil.) ; selangan batu (M.) ; balloiv. In the Singapore market, 
this wood is known as ballow and has supplanted the “Johore teak” ( Pari - 
narium oblongifolium Hook, f.), which was the original wood sold under 
that name. In Burma, the wood which seems to be the commercial 
equivalent of this is known as thingan. Yacal seems to be supplied 
by Shorea balangeran Burck and other species of Sliorea. Some of it 
is also supplied by Ho pea odorata Eoxb. and other species of Hopea. 
The name yacal seems to be the most used name for this wood. Large 
quantities of this wood are used in the Philippines for railroad ties. 
Perhaps the largest place of export for the wood is British North Borneo, 
where it is locally known as selangan bat-u and Borneo yacal. 
Wood very hard and heavy to very heavy, brownish when first cut but 
rapidly darkening on exposure to the air. Always giving a very glis- 
tening surface in transverse section. Pores more or less distinctly 
fringed and with occasional indistinct bands of wood parenchyma. Eesin 
distinctly present. Eesin-ducts occasionally forming incomplete con- 
centric lines of lighter color than the surrounding wood. Pith-rays 
uniform, fine. A very excellent and durable wood, which is said to be 
free from insect attacks.

MANGACHAPUY. Plate XXVII, fig. 68. 
Much like preceding but lighter in color and weight. 
This wood is also known by the following names : gagil and selangan 
batu No. 2 (British North Borneo) ; chengal No. 2 (Federated Malay 
States); Teaniongan (Dutch East Borneo). 
The source of this wood seems to be a group of small leaved Hopeas, 
of which Hopea acuminata Merr. is one.
