These samples arc not specially rich in iron, but serve to show that 
the whole mass of this hill contains a large amount of low grade ore. 
The three samples analyzed are from the top, middle and bottom of 
the section. 
On the small island in the northern lake a dill' of limestone w*as 
found. The beds e.xpo.sed are somewhat similar to those seen on the 
Ekw.an at the upper rapids. In this clilf there seems to be a great 
mass of bioken fragments of corals ami shell.s, mixed with what 
ajjpoars to he limestone fragments, the whole forming an agglome- 
rate. The colour is an a.shy gray. Beneath the water the beds are 
yellowish and of a fintn* grain. A few badly pre.served fo.ssils were 
collected, but among the.se Dr. Whiteaves has recognized or described 
the following species ; %aphr'>nfh Sinkenii : Farnsites Hising^ri : Fh(v- 
nnporn Keciralimuisis ; StropheoiUmta .sp. indet. ; A\>aga- 
rnvais (1): Encrinnnuf sp. indet. Limestone fragments are numerous 
.along the shores to the south of this, to within four miles of the 
narrows, and are derived no doubt from the hods beneath the water. 
Tiinhfr. Southern lake, limestone pebbles arc also numerous, but 
they arc mixed with fragments of other rocks and are derived 
from the boukler-chiy of the hanks, while marine shells from the 
upper marine day are also mixed with them. The timber .seen 
along this lake, is mostly spruce and tamarack. The heaviest growth 
is in the valley at tlie .southern end of the lake, and along the 
small streams draining into it from th<3 west. In going up the lake, 
the timber gradually becomes smtdler, though at the portage between 
the two lakes, there is a f;iir grove of spruce, and a few poplars 
form a fringe .along the southern slope and on the lower ground 
south of the narrows, fn the nortlnmn part there is one grtjvo of 
poplar on the western side, four miles north of the narrows, 
growing on a ridge which seems to be made up of lime stone 
fragments and therefore well drained. Tliis grove i.s i|uite park- 
like, it being carpeted by grass iirstead of the almost universal 
moss which seem.s to cover the whole country. The spruce is 
mainly the black species (Picja nigra) and scarcely any lree.s of the 
white spruce are seen. Of the poplar, both species are found on the
