northward for about 2 miles and as isolated patches as far as Tubbut. 
The soil furnished by this ancient Tertiary basalt is exceedingly fertile and 
huge trees are growing upon it at Bonang. This flow was no doubt con¬ 
temporaneous with the extensive area at Gelantipy.

MT. DEDDICK AND ACCOMMODATION CREEK, EAST 
GIPPSLAND. 
By E. J. Dunn , Director , Geological Survey. 
* Mt. Deddick. 
Mr. Maryatt’s (sen.) house is about 2 miles northward from Bonang, 
at a height of 2,000 feet above sea-level. From this point a start was 
made for the Mt. Deddick mines. For the first mile westward beds of 
Ordovician sandstone and slate in which some auriferous quartz veins have 
been found were traversed. Then a belt of basalt half-a-mile wide and 
some more Ordovician. Three miles from Maryatt’s, grano-diorite begins 
and this continues the ay hole way to the Snowy River, except for a narrow 
belt of Ordovician on the Avest side of Cobanandra Creek, which is 5 miles 
from Maryatt’s. The height of Cobanandra Creek, Avhere crossed, is 1,800 
feet. At Little Gulf (altitude 1,400 feet), 13 miles from Maryatt’s, the 
rock is grano-diorite. At Jingallala Creek, which is about four miles from 
the galena mines, and at the north-west foot of Mt. Deddick, the country 
rock is grano-diorite. Height 800 feet above sea-level. Jingallala Creek 
runs into Deddick Creek before the latter flows into the Snowy River. 
Mt. Deddick forms a range of mountains, 2 or 3 miles long, which stand 
out prominently and which appear to be formed of grano-diorite, porphyry, 
&c. This range is bold and very rugged, and on the top there is said to 
be a plain of considerable extent. 
Most of the Mt. Deddick silver-lead lodes occur right on the east bank 
of the Snowy River and about 2 miles below where Deddick Creek joins 
Snowy River. The Snowy River at this point is 750 feet above sea-level. 
The country rock in all cases is grano-diorite. 
James’ Lode. 
This lode is being opened up about half-a-mile due east from the river. 
The strike of the lode is E. 15 deg. S., and the dip northwards. Where 
the shallow shaft is being sunk good lumps of galena are found on the 
surface and down on the wall. Half-a-chain east of the shallow shaft,
