Thi>>r ihpoxlts nrtrrun l>y tlif gJncli r. — Tliese deposits l)elow the 
front of the glacier are overhiid by a stratum of varying thick- 
ness of true morainic material, rough boulders of varying sizes, 
few of which show any evidence of attrition, lying on or embedded 
in a layer of sand and clay. The surface presents numennis •' kettle- 
holes' ' and kames, its whole configuration being evidently due to a re- 
treating ice sheet. On each side of the inlet the glacier overruns 
these deposits. (Plate 111.) This is best shown (tn the eastern 
side, where b}- passing down the beach to the ice front, a beauti- 
ful longitudinal section of the ice lying above the gravels can ])e 
seen. The length of this section is a quarter of a mile. At its 
upper end this ice has a thickness of one hundred feet at least, 
thence diminishing gradually to an edge. This section is made 
possible because the wings of the glacier on land, reach further 
to the south tiian the seaward portion. On reaching the main 
front the gravels are seen to pass under the ice, so that their 
extent in this direction cannot be told. There is something more 
here than the snout of an advancing glacier riding up over its 
moraine. This glacier is retreating, and all the evidence shows 
that it has been doing so for a considerable length of time. That 
these beds were deposited before the advance of the glacier, from 
which it is now retreating, took place, is proved by the buried 
trees shortly to be described. That the present retreat has been 
long continued, is shown by the condition of the eastern portion 
of the glacier. A glacier of great thickness has advanced over 
these gravels, and done .so for a considerable time. Much of 
their original mass has doubtless been removed. But the very 
considerable remnant is full of significance. The influence of 
the ice upon it must have been more protective Hum anything 
else. At the present time ever}' one of the frequent rains washes 
down portions of this deposit into the inlet and the rapid, ever 
shifting sub-glacial streams are constantly undermining its clifi's. 
so that its mass is being diminished with comparative rapidity.
