He then refers to the belt of " Ipswich " formations north of the " Bundamba " 

 sandstone. They are — 



(a) Shales, limestones and calcareous sandstones with typical calciphile flora, including Bloly Box 

 (E. rariflora, not Cambageana), Poplar Box (E. populfolia). (p. 13.) 



(b) Sandstones of the same series, which are of a micaceous felspathic nature, with good and light 

 loamy soils suited for agriculture, where the country is not too rough. Trees — Spotted Gum, Silverleaf 

 Ironbark. 



Then he deals with the Drummond Range, and the formations at Bogantungan 

 and the tributaries of the Nogoa and Belyando are divisible into an upper calcareous 

 shale series and a lower sandstone series. The former yields good pastoral country, 

 timbered chiefly with Silverleaf and narrow-leaf (E. crebra) Ironbarks ; the latter is 

 poor sandy country with the usual calciphile flora Ironbark (E. siderophloia and 

 E. crebra), Moreton Bay Ash and Yellow Bloodwood (E. Irachyphloia). 



On the flats where the soils mix we have Yellow-jacket (E. Watsoniana), Blood- 

 wood (E. terminalis), and Cabbage Gum (E. papuana) (p. 14). Then we have (pp. 

 14-16), a tabulation of the forest flora geologically classified, and which is a useful 

 abstract of the results of the preceding papers. At p. 17 we have a useful abstract 

 showing the nature of the soils on which the Ironbarks occur, and at p. 18 the soils 

 which some other Eucalypts prefer. 



Dr. Jensen reverts to Queensland in the issue of October, 1922, p. 297. He 

 says that North Queensland is, from the physiographic standpoint, referable to three 

 divisions : — 



(a) The Pacific Slopes, with high rainfall, rich soils, and rough topography. 



(b) The Mountainous Mining Belt, with poor soil, medium rainfall, rough barren topography, and 

 very rapid drainage. 



(c) The Gulf Country, which is roughly divisible into the same zones as the Northern Territory, and 

 has the same characters. 



He then deals with the physiography, soils, and timbers (trees) of various sub- 

 divisions, as follows : — 



The Cairns Coastal Belt. — " The usual tropical Eucalypts/' 



The Kangaroo Hills District. — Spotted Gum (E. maculata), Woollybutt (E. miniata), Ironbark 

 (E. siderophloia), Bloodwood (E. terminalis), are the principal forest trees on the hills. On the granite 

 areas the dominant trees are E. grandifolia, E. alba, and in moist places E. papuana ; on the metamorphics, 

 Ironbark (E. crebra) predominates; on the basalt around Mount Fox, Bloodwood (E. corymbosa, 

 E. terminalis), Box (E. microtheca), and Blue Gum (E. tereticornis) abound, while on the desert sandstone 

 we have abundant Yellow-jacket (E. trachyphloia), Ironbark, also E. setosa and stunted Bloodwood. 



Cooktown District, and Back Country. — The granite slate soils near Cooktown have the usual tropical 

 Eucalyptus flora (E. papuana, E. grandifolia, E. terminalis, E. alba, E. telrodonta, E. crebra). The sandstone 

 soils have only stunted Gums. Bastard Bloodwood (E. iMifolia (?) or E. dichromophloia) and E. crebra 

 occur on a few conglomerate areas. The trees observed to be most abundant on the Little Laura sandstones 

 ere Stringybark (E. tetrodonta), Bloodwood (E. terminalis or E. Abergiana (?) ), Gum (E. grandifolia), 

 also erroneously called Moreton Bay Ash.
