consisting of masses heaped one on the other and of loggan stones. 

 The lower are generally east and west, level at their tops, with now 

 and then rounded summits terminating by rather an abrupt slope s 

 and containing vallies having the appearance of the embrasures of a 

 fortification ; I recollect seeing the above hills mentioned by Colonel 

 Mackenzie in his journal. The basis of all these hills is granite, red- 

 dish and of a small grain.

 infiltration: the temperature of one was 10 degrees lower than that of 

 the atmosphere which was 88°. The wacke was not very general and 

 appeared only in beds of small extent, the general rock being an 

 earthy greenstone with no crystals of any description. I found in all 

 the sides of the streams the efflorescence of the carbonated alkali, and 

 I am at a loss to determine, whether it proceeds from the soda of the 

 zeolite or the potash of the green earth. A dense precipitate was occa- 

 sioned in water from a spring in the neighbourhood of the camp by 

 alum in powder. I arrived at Daigloor, a short time before sunrise ; 

 about a mile distant I crossed a river, the bed of which was composed
