 Coal- Measures, as the Geological Map of Queensland leads one to 

 suppose. Lithologically the sandstones of Caloundra and Lands- 

 borough are identical with those of Point Arkwright, Noosa and

Tewantin. In view of these facts, I consider that, until further 

 evidence is available, the Ipswich and Burrum Coal-Measures 

 should be considered identical (Text fig.l). 



The soil of this belt of country is sandy and poor. The vegeta- 

 tion is of a forest type. Between Landsborough and Narangba 

 the country is low-lying, sometimes almost flat, more often 

 gently undulating. Between Landsborough and Nambour it is 

 decidedly rugged and much more elevated. The coast is lined 

 with swamps, salt marshes and useless tea-tree flats. True scrubs 

 occur on many of the alluvial soils along the rivers and creeks? 

 as well as on the basaltic hills of Buderim Mt. and Sippy Mt. 

 The so-called " bastard scrubs," with a mixed forest and scrub 

 vegetation, occur in many of the gullies in the rugged country 

 between the Blackall Range and Buderim Mountain. 



The Glass House Mountains, Buderim Mountain, Mt. Coolum, 

 Mt. Peregian and many other hills rise abruptly out of the low- 

 lying and Hattish sandstone country. About four miles to the 

 north-east of Beerburrum there is an outlying trachytic hill, 

 Barren Mountain, 350 feet high, situated in a most inhospitable 

 part and surrounded by swamps.
