near the surface of the terrace'— here about fifteen feet above the 
stream. The e-a-stern edge of this terrace slopes steeply to the sea and> 
.as it is wooded to near high tide mark, scarcely any trace of it is seen 
from the sea. The tide flat which borders the co.ast Is probably derived 
from the denudation of the edge of this terrace. The absence of cliffs 
or cut-banks along the coast would indic.ate a recently receded shore- 
line.

The .surface of the terrace was found to be covered witfi a thick coat- Timlx'i con- 
ing of ino.ss, and the timlieron it is mostly .small spruce and tamarack, spr'ncv 
Suine of the trees might be from si.x to eight inche.s in diameter but tamanack. 
the average is much less. At tlie edge of the hank a fringe of larger 
tree.s occasionally appears, but itdoe.s not extend far from the .stream. 
The exposuro.s on the banks show the terrace to be made up mostly of 
stratified clay and .sand, near tho surface, with a line clay of soft te.xture 
beneath. Of the houlder.s and pebbles in the channel rif tlic stream 
and along the sloping Imnks, ^ully fifty per cent are of light yellowish- 
gray limestone and the remainder are of ITuronian and Laurentian 
crystallines. Occiisionally, bits of red quartzite and iron-bearing shales 
from the rocks of the N'aslapok/i (! oup were seen, barge boulders of 
greenstone, having rounded inclusions of coarser texture an<l lighter 
colours, occur here us well as on most of the streams entering Jameg 
bay. Those arc also probably derived from the amygdaloitls in the 
upper part of the Cambrian sections found on the east side of Hudson 
bay. 
Not far from the mouth, the river again divide.s into a number of 
channels, and tlio banks in this vicinity are only about ten feet high. 
The current inoreasc.s slightly and several swift place.s are caus«d by 
an accumulation of boulders in the channel. .\ small br.anch channel, 
running north to the hay north of Niahkow point, leaves the river 
from behind some of the islands of this group. The river continues 
with swift current and i.s divided in a few places by islands. 
Thirty-three miles from the mouth, the first strong rapid occurs, and 
the underlying limestones outcrop ,in a ledge running across the bed of Foti.sil.-.. 
the stream. The bed.s are lying appiareritly horizontal, ami are of a 
grayish-white dolomitic lime.stone holding a few badly preserved fossils, 
from which Dr. Whiteaves describes or identities the following : —
