Abandoned Beaches of Lake Superior. — Taylor. 123 
es at 61.3 feet, 28.4 feet and 13 feet. The exact correlation 
between the beaches and river terraces was not juade out. It 
is evident from the eastward slope of the terraces at the bridge 
that the bed of the river has shifted continually eastward at 
that point during the falling stages. 
East of Nipiyon. For much of the way from Nipigon east 
to Winston's the railway lies on laminated silt beds, usually 
between 20 and 50 feet above the lake. At Gravel river there 
are extensive gravel beds near the station which appear to be- 
long to a delta deposit made at a level considerably higher 
than the station which is 24 feet above the lake. Tliey ap- 
peared to reach up at 40 or 50 feet above the station, but 
whether they belong to the Nipissing or a lower beacli was 
not determined. 
At a point about a mile west of Winston's the Nipissing 
beach appears in fine form and a great ballast pit has been 
opened in it, showing false bedding with eastward pitch and 
sand overlain by clean gravels. The gravels at Winston's 
station are at a higher level (210 feet or more, Lawson). 
, Schreiber. Lawson's observations at this point were veri- 
fied and one additional terrace about ten feet higher than his 
highest was found. About a quarter of a mile northeast of 
the station, along the base of the hills where a small stream 
comes in, there is a small terrace which seems to be the mod- 
ified delta of the streani. It is not wide, but is distributed 
some distance along the base of the hill. Its features suggest 
that it marks a former level of the lake at about -tOO feet. A 
day was spent at Schreiber and an excursion was made up the 
flat little valley into the hills back of the town and up 
to the summit of those situated about two miles to the north- 
east, reaching a hight of 270 feet above the flat. No evidence 
of higher submergence was found, although the little valley 
should apparently have afforded as favorable an opportunity 
for a delta deposit above 400 feet as it did below. Down 
toward the lake an effort was made also to locate the Nipis- 
sing beach. But the brush was so thick along the trail fol- 
lowed that no satisfactory result was attained. There are 
several faint beaches covering an interval of a few yards be- 
low the highest beach, the most prominent being at about 345 
feet. Below this are clay and silt beds 35 feet deep. Only
