The town of Herberton is situated at an altitude of about 

 3000 feet in the valley of the Wild River (the northernmost 

 tributary of the Herbert River), which rises on the range that 

 divides the basaltic area of the Barron Valley from the granites, 

 porphyries, and sandstones of the stanniferous country. 



The ranges attain their greatest altitude, about 4400 feet, 

 at Stewart's Head. 



I am indebted to Mr. E. B. Ranken, Government Mining 

 Surveyor, for the topographical portion of the map attached to 

 this paper. 



The area to which this paper refers is that portion of the 

 Dividing Range between the head of Slaughteryard Creek, on 

 the south, and the head of the Wild River Valley, on the north. 



I have had considerable difficulty in compiling these notes 

 owing to the mountainous nature of the country. The Range 

 between the Walsh and Wild rivers is extremely rough, rocky, 

 and in many places precipitous, and the hills are mostly thickly 

 timbered, and clothed with long coarse grass, so that it has been 

 by no means easy to find creeks or gorges where sections of the 

 rocks were exposed to view. 



In the middle of the year 1894, I found a large bed of 

 conglomerate on a lofty ridge overlooking Grant's Creek, and I 

 have since traced the Sandstone series in a northerly direction 

 along the range. 



On the eastern side of the town, where the most productive 

 tin mines are situated, there is, so far as my observation goes, 

 no trace of the conglomerate and Sandstone series, and on the
