The most shapely of the above Euoalypts will almost invariably 

 be found to be E. resinifera. Growing on the deep clay, this 

 tree is of slower growth, and good spreading habit; and, with 

 its fairly broad dark green leaves, it throws a most agreeable 

 shade. As it is very hardy, and will grow in almost any soil, 

 clayey and sandy alike, it is a pity it is not more extensively 

 planted for ornamental purposes and as a breakwind. The timber 

 is also of value commercially. Near Rook wood, a few E. hfema- 

 s)!o77ia(Scribbly Gum) may be seen on poor clay soil, which pro- 

 bably is not very deep. As one proceeds westwards along the 

 deep clay-formation, the proportion of E. tereticornis and E. 

 hemiphloia increases, and this is the well-known type-locality of 

 the latter. More E. eugenioides, too, is seen, and around Fair- 

 field, Westmead, and Merrylands, E. crei?-a( Narrow-leaved Iron- 

 bark) makes its appearance, the atmosphere here, on account of 

 the absence of sea-breezes, being drier and hotter in summer. At 

 Fairfield and Cabramatta, a few specimens of E. paniculata 

 (White Ironbark) occur, while E. siderojMoia is very plentiful. 

 Dr. Woolls has recorded E. .sic?eroajy^ori( Red-flowering Ironbark) 

 as growing in this neighbourhood, but it seems to be very scarce, 

 having been almost cut out by timber-getters. The most remark- 

 able instance of localisation of a species is that of E. macidata 

 (Spotted Gum). This, one comes on quite suddenly at Smithfield, 

 extending in a westerly and southerly direction, where it forms 

 the bulk of the forest vegetation, being associated mainly with 

 E. eugenioides and E. siderophloia. Moreover, the soil on which 

 it occurs, does not seem to differ materially from that around, 

 being a stiff clay with much ironstone therein. Mr. R. H. 

 Cambage has recorded E. macidata between Camden and Burra- 

 gorang, and it also occurs at Gosford, Clyde River, and other 

 parts of the coast of New South Wales, apparently in the same 

 patchy way. There must be some particular conditions of environ- 

 ment that are always requisite for its growth, but exactly what 

 these are, it is hard to say. Around Cabramatta, Woolls has 

 recorded E. Bosistoayia, and Mr. J. H. Maiden has recently 

 described E. Boormani as occurring. With regard to E. capi- 

 tellata(hvo\\n Stringybark), which Woolls has recorded for Par-
