-M The American Geologist. November, 1894 : 
high bank on the east side, which showed a splendid section 
of the fine-bedded silts and indicated that the whole plain 
over which we had passed is of that composition. There are 
also several dunes on the plain. Southeast of the station 
along the base of the hill there is a cut terrace about 20 feet 
above the flats. The flats themselves extend about two miles 
southward to the south end of the long trestle. They are ap- 
parently perfectly level, and just under the south end of the 
trestle there is a terrace in the same relation to them as that 
near the station, and it is probably a continuation of the 
same. In September, when I revisited Trout Creek alone, it 
rained harder than before; but I walked half a mile up the hill 
to the east and reached a point about 110 feet above the level 
of the station. At that place there appeared to be a sort of 
shelf facing the northwest and covered with a great number 
of boulders of large size. There were so many of them five to 
six feet or more in diameter that the road had to be crooked 
about to find a way among them. The altitude of this place 
is about 1,145 feet above the sea. On the basis of the obser- 
vations at Sundridge and South River the boulders on the 
hillside are probably somewhat less than 100 feet below the 
leyel of the highest beach. Considering the very exposed 
position of this hillside, I should expect to find the highest 
beach strongly developed. From this point the hills at the 
supposed hight of the shore line extend slightly north of east 
to the valle}^ of the Ottawa river and also toward the west- 
southwest 30 or -40 miles. Pawassan, seven miles north of 
Trout Creek and about 175 feet lower, is also an interesting 
locality. Besides fragmentary beach ridges of gravel, the 
silt beds are extensively developed and lie apparently in a 
more exposed position than usual. Of the other localities far- 
ther north, which were visited on these excursions, a separate 
account has been given in Miother article,* which is virtually 
a continuation of this although it was earlier in publication.
