dealing with the area are chiefly concerned with the mining geohjgy, 

 and general mining features, and very little space in them is 

 devoted to purely geological questions.

A. — Silurian Sediiuents. 



These are the northern extension of the same folded sei-ies of 

 sandstones, shales, and gritty beds that occur near Warrandyte and 

 Diamond Creek, and with the exception of the igneous rocks near 

 Yow Yow and One Tree Hill, they cover the whole of the area 

 described in this paper. The strike of these beds is consistently 

 east of north, varying from north IQO east to north 5()o east. As 

 in the sediments of the country to the south near Wai-randyte and 

 Diamond Creek, fossils are relatively .scarce, and the only ones 

 found by the present writer were two specimens of Chonetes allied 

 to Chonetes melbournensis, wliich latter form is restricted to the 

 Melbournian division of the Silurian. These fossils were discovered 

 in black, sandy, occasionally gritty shales from the nmllock-tip 

 of a shaft on the Victoria line of reef. One Tree Hill. Selwyn has 

 recorded fossils similar to those occurring in the gritty beds near 

 Warrandyte, from Watson's Creek about six miles north of War ran-
