are narrow^ and of no commercial value as limestones, yet tlie amount 
of weathering along Mt. Pleasant and its adjacent spurs must have 
added a quantity of lime to the soils, which have been washed down 
the King River valley. 
It may be here mentioned that the King valley possesses three 
favorable and adjacent formations to account for the richness of its 
soils. On the east there are the small series of phosphate-bearing 
rocks of the Upper Ordovician formations, on the west the basalt 
tableland which has supplied a certain amount of lime to the soils, 
and on the south the Mt. Pleasant area already described. 
Included in the analyses there is a sample of limonite collected by 
Mr. McKenzie, Inspector of Mines, from an extensive iron ore 
deposit on the Stoney Creek fall and below TyrelPs gold mine, in the 
Black Range. This limonite yielded a fairly high percentage of iron 
(assay Ko. 397). The softer sienna-coloured ore which accompanies 
the limonite might be used as a pigment body. A sample of gem sand 
was washed from the terrace drift on the western side of the King 
River valley, about 1 mile northerly from Whitfield township, and this 
contained a fairly large percentage of small fractured garnets of no 
commercial value.
