Pseudocedrela are such, for it is known that African cedars are largely 

 derived from this genus. Other genera (see Mahogany) also supply 

 African cedars and mahoganies. To distinguish between the cedars and 

 mahoganies of Africa should not in reality be difficult, though customs of 

 the trade have made it so. Several so-called mahoganies have the same 

 kind of thin, sinuous light lines shown in cross-section ; among them 

 are Sapeli, Warri, Jameson River, Sekondi, and one variety of Bonamba. 

 Of these, the first two are scented ; in fact, SapeU ' mahogany ' is stated 

 to be derived from Pseudocedrela. 



" The wood does not show in cross-section any distinctly marked 

 annual rings or similar belts (though certain darker bands divide the 

 surface into ring-Uke zones) ; but very numerous, fine, concentric sinuous 

 lines are visible to the naked eye and cross the medullary rays at right 

 angles ; the pores are visible but rays invisible to the naked eye." 



Cedar, White. 



The following, aU of which come from the United States, are the 

 timbers known in commerce as white cedar. They are, however, seldom 

 seen in this country, and are of Httle commercial value : 



Libocedrus decurrens, Torrey. 



Cupressus thyoides, Linn. 



Thuja occidentalis, Linn, (see Arbor- vitae). 



Cedar, Yellow. Cupressus nootkatensis. Hook. Weight, 20 lbs. 

 (Boulger). Canada, United States. 



This wood, which should perhaps be more correctly termed a c}q)ress, 

 is of a light yellowish-red, and has sometimes a very handsome grain. 

 It is not known commercially in the United Kingdom, but is generally 

 reported as being exceedingly durable. 



Chaplash. Artocarpus Chaplasha, Roxb. Weight, 34 lbs. India, 

 Burma, the Andaman Islands. 



This wood has a very attractive golden-brown colour and a satiny 

 lustre. As it is somewhat cross-grained it requires careful planing with 

 a sharp tool. Although suitable for decorative cabinet work on account 

 of its appearance it should not be used in large or unsecured work, as 

 the nature of the grain renders it liable to warp to a certain degree. 

 Gamble says : " It should be seasoned standing by ringing, so as to 

 prevent warping when cut and sawn," and quotes Chevalier Paganini, 

 who says he " considers it equal to or superior to teak for household 

 furniture." 



The pores are rather scarce, not large, and generally plugged, but 

 show prominently on the tangential section rather prettily in a somewhat
