and it would be interesting to know how far they continue down 

 the river, as although this species is common on the higher parts 

 of our large streams, it gradually disappears as the western levels 

 are reached. 



Callitris calcarataj the Black or Green Pine, so called from the 

 colour of the bark and foliage respectively, was noticed only on 

 the sandstone area previously mentioned. This species is 

 generally found occupying elevated land, often somewhat rocky 

 ridges, and it is not usually found on the low land with C. 

 robiistay the White Pine. 



In writing of these two species (Lectures on the Vegetable 

 Kingdom, p.73), the Rev. Dr. Woolls says : — " These fine trees 

 differ in habit, for whilst the black pine has a pyramidical ap- 

 pearance, branches somewhat upright, and branchlets rather 

 close, the white pine is a larger tree, with a lighter bark and 

 branches deflected, and turning up again from their ends," 

 (Pls.xxiv.-xxv.). 



Between Narrabri and Moree the following Eucalypts were 

 passed : — B. rostrata, E. tesselaris, F.v.M. (More ton Bay Ash or 

 Carbeen), B. Woollsiana, E. popuU/olia, E. melanophloia, and a 

 few trees near Tycannah of what appeared to be E. largiflorens, 

 F.v.M. (River Box), but their identification is doubtful. 



E. WooUsianq, was not seen during the last 40 miles, or scarcely 

 north of Edgeroi, but although it grows on flat land it is not a 

 typical tree on any of the black soil plains. It was noted again, 

 however, at about 15 miles east of Moree. In different localities 

 its leaves were noticed to be remarkably narrow. 



It may be observed that the species of Eucalyptus are not 

 numerous between Narrabri and Moree, and although these places 

 are sixty miles apart the intervening country is really one vast 

 plain, long stretches at intervals being naturally destitute of 

 trees of any description. The difference in levels between the 

 two railway stations is only 11 feet, while the highest point 

 between them is about 100 feet above the terminals. 



Other trees and shrubs observed between these towns were: — 

 Argemo7ie mexicana (an introduced rather pretty flowering, so-
