also in large numbers in deeply decayed and bleached sandstones 
at Grosse Isle head, indicating the eolian character of that rock 
formation. On Grindstone island an irregular gravelly layer of 
“small angular diabase pebbles’* accompanied by larger boulders 
is said to occur similarly in decayed sandstone. 
Summing up the reports of these three observers, we learn 
that: (a) a sheet of rotten sandstone of strictly residual origin 
and quite undisturbed by glacial action covers much of the 
surface of the Magdalens; (b) in places this deposit contains 
boulders and pebbles of quartzite and chlorite schist, whose 
surfaces seem in no case to be ice worn but are frequently sand 
blasted; (c) no glaciated surfaces have been found on the islands 
and no boulder clay is known to occur there; (d) such crystalline 
boulders as are known to exist at certain places on the beaches 
may have been transported hither by pack ice either in modem 
times or during the period when the upper sandstone accumulated, 
being subsequently released from it by weathering; and (e) 
there are somewhat questionable evidences of marine submergence 
to about 100 feet. 
NEW OBSERVATIONS, 
Early in September, 1913, the writer paid the Magdalens 
a brief visit in order to see if possible whether evidences of glacia- 
tion there were indeed absent; for the season’s field work in 
Nova Scotia and Cape Breton had pointed rather to the probabil- 
ity that these more northerly islands also had been reached by 
the continental ice sheet. In order to ensure getting results 
within the limits of time that remained, the plan was hit upon 
of leaving the mail boat, “Lady Sybil” at the first promising 
spot where a landing was made, and remaining there for field 
work until the return of the boat several hours later. Thus it 
was hoped definite knowledge might be obtained on at least one 
of the islands. It happened, however, that at Amherst, where 
the first stop was made for 20 minutes, a deposit of boulder clay 
was found within 3 minutes’ walk of the pier, and glaciated stones 
were collected from it; so that it seemed advisable instead of 
remaining there to go ahead with the boat, and by similar half-
