TECHNOLOGY AND ANATOMY OF SOME SILKY OAK TIMBERS. 369 
EMBOTHRIUM WICKHAMI F.v.M., Satin Silky Oak, Red 
Silky Oak. (See Bailey’s ‘‘Queensland Flora,”’ iv, 
1358). 
Remarks.—This is easily distinguished from the other 
Silky Oaks by its specific gravity being the lowest. The 
first common name well describes the face of a planed 
surface. 
Range.— Brushes of the North Coast of New South Wales 
and the coastal districts of Queensland. 
Timber.—(a) Macroscopical.—Physical Properties. 
Colour.—A. pale pink. 
Figure.—This has quite a different facies from any 
described Silky Oaks. The figure is a decidedly “‘Oaky”’ 
one, and its sheen adds to its beauty. The rays are 
prominent, but the open texture along with the sheen 
rather adds to the ornamentation of the timber. It is the 
most porous timber of them all; most of the fibres occur 
in bundles. 
Texture and Grain.—This is the most open grained of all 
‘the Silky Oaks and naturally the specific gravity is the 
lowest, and although the rays are very prominent, yet it is 
not interlocked, the fibres running quite straight, and so it 
is easy to plane. The rays are of a darker shade or colour 
than the other wood elements, which possess such a very 
high sheen or satin surface that in cabinet work, especially 
panelling, there would be no necessity to polish it. It 
planes and works very easily. 
Weight.—30 tbs. per cubic foot. 
(b) Microscopical. 
Transverse Section.—This is quite unlike in structure any 
of the other Silky Oaks described in this paper, in fact, 
unlike any other Proteacez so far examined by me. The 
X—August 7, 1918.
