BED EUCALYPTUS WOODS. 



In addition to the points already mentioned, the rod Eucalyptus woods 

 frequently have two- or three-layered pith-rays. The yellowish crystalline 

 substance in the cells seems to be sometimes only sparingly present Cal- 

 cium oxalate seems to be wanting. Chips coloring alcohol or water, the 

 latter more darkly red, without the content of the cells being noticeably 

 dissolved; it remains unchanged in boiling water and is only dissolved 

 when quicklime is added. The unchanged contents of the cells deeply 

 blackened by iron chloride. 



Of Eucalyptus species with red wood, the following are to be placed 

 here : 



Eucalyptus crebra P. v. Mueller. Ironbark in New South Wales, Queensland 

 and north Australia. 



Eucalyptus marginata Km. The jarrah or bastard mahogany. 

 West Australia; cultivated in British India. 



Wood hard, sapwood white, heart wood red. Pores small, scanty, scat- 

 tered unevenly, but chiefly in pale concentric bands. Pith-rays very 

 fine, very numerous. Heavy construction work, piling. 



Gamb. 353; Van Eed. 133; Stone 114; Stevenson 250-254. 



Eucalyptus rostrata Sehl. Red gam, West Australia. 



Eucalyptus resinifera Smith. Forest-mahogany, West Australia. 



Stone 115. 



Very many other species are used, but those mentioned are said to be the 

 onea most commonly exported. Many of these woods seem to have proved quite 

 durable for street paving in temperate regions. 



Eugenia. Plate XXIX, lig. 89. Wood rough, moderately hard to 

 very hard, seasons well, usually reddish- or grayish-brown. Pores small 

 to moderate-sized, more or less arranged in concentric bands, sometimes 

 joined by pale 1 issue of large wood cells. Pith-rays fine, numerous. A 

 xwy targe aumber of species, which are very difficult to distinguish. 

 The timbers are usually good, and some are exceptionally so, and can be 

 \\^^\ for house or ship building. In the Philippines, woods of this genus 

 are known as macaasin or malaruhai. In the Federated Malay States, 

 they are known as Teayu Mat Some very fine and some rather indifferent 

 woods belong to the genus; but, as yet, I have not been able to properly 

 classify them. Many of the species of Eugenia arc of very scattered oc- 

 currence and do not grow to unusual size, consequently they arc not a 

 very considerable factor in the market.
