toughness is required. Differs from Ironbark, inasmuch as the 

 log when drying at the butt cracks in rings, while Ironbark 

 radiates from the centre" (Forest Ranger Marriott). Mr. 

 Marriott called this timber " F. bicolor," an error which has been 

 referred to at p. 520. 



Mr. A. G. Hamilton (these Proceedings [2], ii., 277) states 

 that the " Slat}' Gum " is common on the ridges at Mudgee, 

 where it does not attain a great size, but on the flats at Tallewang 

 it runs up into splendid trunks, which are much used in bridge 

 building, &c., and the timber is considered very durable. 



"Slaty Gum or Red Box," Lue, Mudgee Line. "Fine large 

 trees, 40 to 60 feet high, patchy or at times quite smooth, white 

 with patches of grey bark; this is more applicable to the large 

 trees; the smaller are more of a scaly nature. The latter desig- 

 nated ' Red Box '; the larger ' Slaty ' or ' Spotted Gum ' " (J. L. 

 Boorman). 



"Slaty Gum," Rylstone. " Large tall trees, clean stems, bark 

 falling away in long ribbons, leaving a clean white stem with 

 patches of dark green, the tips of the branches of a mealy, 

 powdery whiteness, sap timber pale 3"ellow, centre red " (J. L. 

 Boorman). 



" Red Box," Rylstone. " Trees not so large as those known 

 as ' Slaty Gum,' and the bark is more scaly, but in wood and 

 every other respect identical with Slaty Gum " (J. L. Boorman). 



"Red Box," typical for E. ovalifolia, R. T. Baker, Rylstone 

 (R. T. Baker). See H. G. Smith (Proc. R.S.N.S.W. xxxiv. 

 290). Labelled indifferently " Slaty Gum, Red Gum, Red Box," 

 Capertee. " Some trees large and entirely smooth-barked; otliers 

 small and stunted, with a ribbony bark. A large tree which was 

 felled showed narrow leaves at the top " (J.H.M. and J. L. 

 Boorman). 



Following are some field notes : — 



" Cullen Bullen to Capertee. This species reminds one of 

 Yellow Box [E. melliodora) slightly — a ribbony gum on young 

 trees, scaly bark when older, at least as far as the first fork and 

 often beyond. Handsome trees; wood red; we then found a tree
