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 cooperation 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 Piatt's Bank and Jeffrey's Bank, likewise 

 making a station off Cape Elizabeth, one in the deep trough between 

 Piatt'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 leav- 

 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
