the average height is 1,100 feet. The country is very rugged, 

 and the D'Aguilar Range is specially remarkable for the enormous 

 differences in soil, rock-formation and vegetation in different 

 parts. South of Mt. Nebo it is composed of granites and Palaeozoic 

 rocks with a fair soil, giving good pasturage. Between Mt. Nebo 

 and Mt. Mee the ruggedness of the range becomes still more 

 marked, sharp peaks towering aloft from it Judging by their 

 steepness and general configuration, I should take them to be 

 composed of trachyte or rhyolite. The soil of this part of the 

 range is often poor through cappings of sandstone, and rhyolite 

 dykes The timber is of the forest type. At Mt. Mee we 

 obtain excellent soils derived from hornblendic schists and basalt. 

 The basaltic cap of Mt. Mee is covered with scrub. Mt. Byron 

 is separated from Mt. Mee by a deep gorge, Sellin's Creek (a 

 branch of Byron Creek), in which the Mt. Mee basalt is clearly 

 seen to overlie the Mt. Byron keratophyre. Mt. Byron has a 

 forest vegetation with an abundance of macrozamias and grass- 

 trees. The soil is poorish, overlying a soda-rhyolite, though 

 occasional patches of scrub occur on basaltic dykes. 



From Big Hill northwards the poverty of the soil of the range 

 contrasts markedly with its richness on the fertile Mt. Mee 

 Tableland. A small mass of conglomerate caps the rotten granite 

 of Big Hill on the Caboolture- Woodford road. North of the 

 supposed fault sandstone formation is met with. West of Mt. 

 Tunbubudla a mass of volcanic rock (rhyolite quartz porphyry, 

 dacite and basalt) occurs in the range ( Plate v., iii.). 



(c) The Woodford Peneplain.- — Behind the D'Aguilar Range 

 there lies an extensive tract of gently undulating country, 

 through which the Stanley River flows in a shallow bed. This 

 tract has an average altitude of about 500 feet in the Woodford 

 district. The soil is sandy, derived chiefly from rofcten granite, 

 and, the country being open forest land, is well adapted for 

 pastoral pursuits. The decomposition of the granites to great 

 depths probably dates from the time when this country was a 

 coastal plain. Since the elevation of the present coastal plain 

 the direction of drainage has altered, so that the northern
