Wood very hard 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. Resin 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 tin- fad that the tangential section 

 alwaya shows distinct parallel transverse lines (ripple marks). The 

 wood is used lor railroad tics, 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.) ; hallow. In the Singapore market, 

 this wood is known as hallow and has supplanted the "Johorc teak" (Pari- 

 nariuin oblongifolium Hook. f. ), which was the original wood sold under 

 that name. In Burma, the wood which seems to he the commercial 

 equivalent of this is known as Ihingan. Yacal seems to be supplied 

 by Shorca haJangeran Burck and other species of Chorea. Some of it 

 is also supplied by Hopea odorata Roxb. 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 batu and Borneo yacal. 



Wood very hard and heavy to veiv 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 indistincl hands of wood parenchyma. Kesin 

 distinctly present. Resin-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 hut lighter in color and weight. 



This wood is also known by the following names: gagil and selangan 

 batu No. % (British North Borneo) ; chcngal No. '? (Federated Malay 

 States) ; hmiongan (Dutch East Borneo). 



The source of this wood seems to be a group of small leaved Hopeas, 

 of which "Hopea acuminata Merr. is one.
