a small quarry, near Cox's Creek, the junction of the granite 

 with the slate rocks, and its intrusions into them, are clearly- 

 seen. The granite crosses the creek at the bridge, and out- 

 crops on the rise of the hill on that side. A district road 

 goes off from the Carey's Gully road, in a southerly direc- 

 tion, through Section 1203, along which the granite can be 

 traced, making bold outcrops on Mr. A. H. Smith's grounds 

 (Section 1133), and was proved in a well near the homestead 

 at a shallow depth, yielding a moderate supply of water. It 

 does not seem to pass behind Mr. Melrose's house (unless 

 very near to it), as a quarry in Aldgate sandstone occurs in 

 the grounds behind the house, with dip south-east at 30°. 

 North-west of the house, quartz and ironstone outcrop ; whilst 

 on the low ground on the north side there is a large outcrop 

 of granite, which is but slightly decomposed. Following the 

 rise to the north-east, there are considerable outcrops of 

 granite in a scrub, and these join on to those already described 

 on the district road at Mr. Smith's, and in the section which 

 shows the unconformity. This granitic patch may be re- 

 garded as about one and a half miles in length by about a 

 mile in width. A special feature of the quartz veins, included 

 in these Pre-Cambrian beds, is that they frequently contain 

 ilmenite plates and nodules and grains, which is presumably 

 the source of the detrital ilmenite abundantly present in the 

 overlying grits and conglomerate. 



The Grey Spur, Inmon Valley. — The outcrop of the basal 

 beds in the Inman Valley district is one of the most marked 

 and instructive of those examined. It is approached by a 

 district road, which crosses the Inman at the eighth milepost 

 from Victor Harbour, passing over a ridge into a lateral val- 

 ley. In this valley, near the homestead of Mr. J. J. Cross- 

 man, is the Dog Hill (Section 84, Hundred of Encounter 

 Bay), exhibiting a very rocky face on its south-east side. This 

 prominent ridge consists of a coarse conglomerate, and was 

 named the Grey Spur by Mr. D. H. Cudmore, of Adare, Vic- 

 tor Harbour, who was the first to call attention to its re- 

 markable features. 



The matrix consists of a coarse arkose grit, the chief in- 

 gredients being quartz and felspar, mostly sharp or but 

 slightly water-worn, and in places fragments of aplite. The 

 pebbles are very numerous, strongly water-worn, and occur up 

 to 10 inches in length. They consist mainly of a very hard 

 siliceous quartzite, with rounded quartz, granitic, and other 

 rocks. Layers and grains of ilmenite are distributed more 

 or less throughout the bed. It is often laid down under cur- 

 rent bedding, showing its derived origin, whilst some of the-
