34 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
According to previous agreement Casco Bay was made our headquart- 
ers until July 31st (Stations 15-20), the vessel being engaged in dredg- 
ing and trawling in the Bay and off its mouth, in codperation with the 
South Harpswell Marine Laboratory. 
On the completion of this work, July 31st, the vessel proceeded 
along the coast as far as the mouth of Penobscot Bay, making one 
offshore Station (21), and numerous hauls in the coastal waters and 
among the islands, while I remained at the South Harpswell Labora- 
tory and titrated all the water samples collected up to that date, a room _ 
being placed at my disposal by the Director, Dr. J. S. Kingsley. I 
rejoined the Grampus at Portland; but owing to heavy weather and 
thick fog, it was not until August 7th that we were able to resume 
work. 
We now ran a triangle to Platt’s Bank and Jeffrey’s Bank, likewise 
making a station off Cape Elizabeth, one in the deep trough between 
Platt’s and Cash’s Ledge, and one between Jeffrey’s and the mouth 
of Penobscot Bay; but on the evening of August 8th, we were driven 
to refuge in Boothbay by thick fog, and lay storm-bound there and 
in Portland Harbor for a week. Leaving the latter port on August 
13th, we commenced a section toward Cape Sable, following the paral- 
lel of 48° 25’, making Stations 27 and 28 in the eastern part of the 100 
fathom basin, and Stations 29 and 30 on German Bank off the Nova 
Scotia Coast on the evening of August 14th in thick fog. The follow- 
ing day Station 31 was occupied off Lurcher Shoal, the exact position 
doubtful because of the fog. That afternoon we spoke a fishing vessel 
lying at anchor on the Grand Manan Bank and making a good fare 
of cod; during the night the fog lifted, allowing us to pick up the light 
house on Petit Manan Island. 
At daylight, August 16th, the weather having cleared, we occupied 
Station 32, some ten miles off Mt. Desert Rock, and then turned 
northeasterly along the coast, making a station off Moose Peak. 
That night we made Station 34 in the Grand Manan Channel, and 
anchored in Eastport the following morning. On our passage through 
the channel we had found almost no plankton, a result in very marked 
contrast to the hauls which we had made off shore and further to the 
west (p. 104); and our run homeward was planned to develop the limits 
of this barren area as well as to trace the breadth of the band of cold 
water which lies close to the coast of Maine. Consequently on leavy- 
ing the Grand Manan Channel, August 20, we ran off shore once more 
to the 100 fathom basin (Station 36) where we found an abundant 
plankton, and then turned northward again, reaching the coast near
