Maiden, 1895. — In my " Notes on the Commercial Timbers of New South Wales," 

 (First edition, 1895), I reiterated the classification of Pale Hardwoods, and added 

 that of Ked Hardwoods for the first time (see p. 131). Although, so far as I know, 

 I may have used the terms Pale and Red for the first time in a scientific classification, 

 I have known timber-men to use these terms as a general classification as long as I can 

 remember. Governor Phillip's woodcutters must have noticed these extremes of 

 colours. 



Cambage, 1913.— Mr. R. H. Cambage, in his presidential address (Proc. Roy. 

 Soc. N.S.W., xlvii, 34, 1913), refers to the colour of timbers in the following words : — 



In studying the dark £,nd pale-coloured timbers, it is noted that in the warmer parts both colours 

 occur, while in the Mountain Region, above an altitude of 3,500 feet in latitude 32 degrees, and at 

 diminishing elevations to the southward, the prevailing colour of Eucalyptus timbers is pale, no red- 

 timbered Eucalypt occurring in Tasmania (R. T. Baker and H. G. Smith make some reference to this 

 subject in Proc. Roy. Soc. Tan., p. 139, 1912). The colouring of dark timbers is evidently due to the presence 

 of some constituent, perhaps developed in response to a plant food, and it seems not improbable that the 

 development of the substance in question is retarded by the cold. The wood of mountain Eucalypts is 

 also regarded as the least valuable for firewood among the genus, which fact implies some difference in the 

 composition of many lowland and highland Eucalyptus timbers. 



Baker, 1913.— In " The Cabinet Timbers of Australia," by R. T. Baker (1913), 

 a few Eucalyptus timbers are shown in colour. They are admirable, and it is to be 

 regretted that more species are not figured, and more specimens of each to show 

 variation. Those figured are- 

 Plate XXX. — Mountain Ash or Tasmanian Oak (the latter a misleading trade 

 name, but in use) (E. gigantea, given as E. delegatensis) ; a Stringybark (E. obliqua) ; 

 Red Mahogany (E. resinifera) ; Jarrah (E. marginata) ; a Red Box (E. Rudderi) ; Spotted 

 Gum (E. maculata) ; Sydney Blue Gum (E. saligna) ; Slaty Gum {E. Dawsoni). 



In the same year, in dealing with Victorian Timber Trees at p. 307 of Report 

 Aust. Assoc. Adv. Science, Mr. Baker says, " No less than seven-eighths of the sixty 

 trees described in this paper are pale-coloured. The red timbers are, therefore, 

 comparatively few, and number less than a dozen." He offers the classification : —

E. rostrata, E. tereticornis, E. longifolia, E. sideroxylon.
