The trees provisionally identified as Acacia doratoxylon 

 (No. 4106) are locally known as Lancewood, and were 

 noticed from near Einasleigh and Wirra Wirra onwards to 

 Croydon. They seem to a^void the basic formations and 

 were seen chiefly on granite or sandstone, and in some 

 cases reached a height of quite forty feet, though they 

 were commonly from twenty to thirty feet. In western 

 New South Wales trees of this species, which are known 

 as Currawong, are usually confined to ridges, but the 

 Lancewood, though common on the elevated land, often 

 grows well down on the slopes where it attains its largest 

 size. 



After the one hundred and fifteenth mile-post was passed, 

 an undescribed species of Eucalyptus appeared, (E. Brownii 

 Maiden and Cambage, these Proceedings, 1913, p. 215). The 

 note made in the train conveys a general description of the 

 tree, and reads : — "A narrow-leaved Box, seems distinct 

 species, rough bark on branches, green leaves." These 

 trees were growing on a contorted micaceous slate forma- 

 tion showing quartz, but they continued intermittently to 

 Wirra Wirra where the rock is sandstone, possibly Upper 

 Cretaceous. This Box tree averages about forty feet high, 

 with small fruits, and according to Mr. Thomas Keller of 

 Wirra Wirra has dark red timber. 



Eucalyptus tetrodonta was first noticed between the 

 twenty-second and twenty-fourth mile-posts from Alma-den 

 and again towards the fifty-first mile-post. It was subse- 

 quently seen at various points along the Gilbert River, at
