100. Mergus merganser, Linn. Goosander.—Apparently common. A 
large brood seen several times on Devil’s Track Lake. When alarmed they 
fluttered along over the surface of the water for a long distance, uttering 
loud cries. They retreated occasionally down the river and probably came 
up to the lake for the purpose of fishing. (Possibly serrator , as no specimen 
was secured.)

seen at Grand Marais, July 28. 
102. Larus argentatus, Briinn. Herring Gull.—Abundant. They are 
said to breed on two small rocky islands near Grand Marais. Stomach of 
-one specimen found full of grasshoppers which it had probably picked up 
from the surface of the water for these insects perish in the lake in count¬ 
less numbers. Grand Marais, Aug. 12.
