stones of grey gneiss, containing well crystallized precious garnets. At the 

 Upper Carrying-Place, mica slate occurs, and half a mile above it vertical strata 

 of gneiss appear, its layers alternating with layers of magnetic iron ore. 



An island, near the centre of Holy Lake, is composed of chlorite, and 

 mica slates. At the upper end of Holy Lake, the designation of the river is 

 changed to Weepinapannis. This stream flows through a marshy country, 

 and is divided by low barren rounded masses of rock into a great variety 



of channels. • , , 



At the Lower Portage, in the Weepinapannis, granitic and hornblendic gneiss 



occur, the former intersected by a vein of red granite. — Moore's Island is com- 



posed of a bed of granite. Half a mile above it, the rocks consisting of 



granitic gneiss are intersected by a vein of red granite. The direction of the 



■ 



strata here is N.E. b. E. and S.W. b. W. — Near the Crooked Spout, hornblendic 

 gneiss alternates with porphyritic granitic gneiss, and red granite passing into 

 gneiss. 



At the upper end of the small piece of water termed the Windy Lake, the 



■ 



stream, now very much diminished, obtains the name of Rabbit Ground. The 

 rocks here resemble those in the Weepinapannis. 



At Hill Gates, the stream runs through a narrow chasm in the rocks, above 

 ten miles long. The predominating rock is grey gneiss, more or less com- 

 pact, and sometimes inclining to granite, but more often to mica slate. Near 

 the centre of the chasm, the eminences separated by narrow valleys, and 

 composed as it were of rounded masses heaped one upon another, rise to 

 the height of two hundred and fifty feet. The predominating stone here is a 

 granite inclining to gneiss. The stratification of the rocks that bound this 

 chasm is obscurely mantleform. 



After leaving Hill Gates we passed through a marshy lake, and arrived at 

 the White Fall, where the stream, rushing through another chasm, forms a suc- 

 cession of cascades. The rocks at this place, consisted of compact grey gneiss 

 containing an extensive bed of graphic granite. Kidneys of a less compact 

 gneiss were contained in the granite. 



A shallow swampy piece of water, bounded by gneiss, conducted us from 

 the White Fall to the Painted Stone, where the principal branch of Hill River 

 may be said to originate. The portage at the Painted Stone is made over a 

 low rock of grey gneiss, much intersected with veins of quartz and felspar.
