360 DESCRIPTION OF THE 
rock is also seen tilted at a high angle near the intersection of the trap-dikes. Be- 
tween this place and the second fall, which is a highly inclined plane, about twenty 
feet in height, the walls between which the river runs are composed of Nos. 288 
and 289. At the second falls I saw no trap-dikes, the water cutting through the 
beds of No. 289. It is very probable, however, that there is a dike at no great dis- 
tance above, as the metamorphosed rocks dip down stream at an increased angle. 
I did not ascend the river beyond this place. 
At the Lower Falls, the changes produced in the sedimentary beds by the intrusive 
rocks, are remarkably interesting. No. 293 is from the north-30°-east dike, in 
immediate contact with the bedded rock; No. 294 is from the bedded rock in im- 
mediate contact with the dike; No. 295 is from the same beds, fifty yards from the 
dike; No. 296 is from the top of the hill east of the fall, and is the same as No. 
291. On this hill, No. 504, which is more highly altered than some of the other 
beds, is associated with a hornblendic rock (No. 305), but in what manner I was 
unable to ascertain. Thin strings of greenstone (No. 297), and veins of No. 298, 
traverse the shaly rock near its junction with the dike. No. 299 is from the shaly 
bed above the falls, and contains organic impressions of the same kind as those 
found on Passabika and Encampment Island Rivers. No. 302 is from shaly beds 
on the lake-shore near the mouth of the river; and No. 303 from the greenstone 
dike already noticed as occurring above, just before reaching Kanokikopag Bay. 
The red beds of this river appear to occupy the same place in the series as the 
porphyritic beds (No. 591) seen near the Entry Point, and the Palisade Rocks, to be 
described hereafter. 
Immediately below the mouth of this river is a north-and-south dike, which ap- 
pears to be the same as the one at the Lower Falls. Beyond this are some expo- 
sures of No. 620, with beds of altered shales and slates. Half a mile below the 
mouth of the river, a bed of trap overlies a soft amygdaloidal shale, of a brick-red 
colour, and containing many small nests of zeolites and other minerals. A quarter 
of a mile further on is an immense exposure of basaltic rock, which protrudes 
through beds of shale. The columns are perpendicular, and contain large angular 
masses of a felspar rock, as exhibited below. 
MASSES OF FELSPAR INCLUDED IN BASALT. 
With the exception of the horizontal prisms seen on the west point of this bay, 
all the columns of basaltic rock in contact with the felspar rock are perpendicular.
