length about three miles, in breadth scarcely one. None of the other 

 knolls are near so extensive, nor do they attain one half the height. The 

 dip of Karana is North to North- West, under an angle of about 35°, that 

 of the salt range being about 15° locally higher,* the strike of both is the 

 same, the distance between forty miles. 



The rock of which these knolls are composed is a compact schistose 

 sandstone, passing into clay-slate or argillaceous schist, of a varying 

 yellowish leaden colour, it has somewhat the appearance of Grauwacke, 

 and bears occasional marks.* 



The Hill is intersected by veins of Quartz with Iron ore (Haematite), the 

 thickness of the vein seldom exceeds six inches of which about 2>\ inches 

 are iron ore. 



Without a thorough examination of the Hill, it is not possible to state 

 in what quantity the ore occurs, though it appears abundant . 



It is difficult to determine at present, the exact age of this formation, 

 whether it belongs to the old red or a still more ancient group, but, that it 

 is of older date than the rocks of the salt-range there can be little doubt, 

 as in this latter no rock of a metamorphic character is found.

 The following is my report on this remarkable ore and my replies to his 

 queries, sent to Major Baker for transmission to Col. Napier. 

 To Major Bakee, B. E. 

 Pear Sie, — I have carefully examined the Iron ore from Karana 

 accompanying your letter of 20th September. Indisposition has prevent- 

 ed my completing my analysis of it so perfectly as I could desire, and this 

 and your early departure prevents me from being quite so precise as to 

 the minor constituents as I could have wished. 



Its composition in 100 parts taken as fairly as possible from the speci- 

 men of ore, to avoid the quartz with which it is mixed, I find to be as 

 follows : 



Water and Carb. Acid, 3.50 



Silex, 11.22 



Alumina, none 



Magnesia, 0.50 



Carbonate of Lime, 65.14
