MUSEUM OF COMPARATIVE ZOOLOGY. 37 



serial temperatures, serial water samples, measurements of ocean 

 currents, and collections of plankton. 



The first field was the cold coastal water between the coast and 

 the Gulf Stream, from Cape Cod to Chesapeake Bay, which was 

 covered in a zig-zag course, making three sections across the 

 coastal bank. Ocean currents were measured off Long Island, 

 off Cape May, and off Chincoteague Inlet, observations being 

 taken hourly, for six hours, at each station, the times being chosen 

 so as to include both ebb and flood tides. The Grampus returned 

 to Gloucester from this first cruise, on August 5; and after refitting, 

 put to sea on the ninth for a cruise in the Gulf of Maine, to repeat, 

 in a general way, the stations of 1912, to discover how closely 

 oceanographic conditions might reproduce those of the preceding 

 season, the opportunity being unusually good, for the air tempera- 

 tures of the winter of 1911-1912 had been exceptionally low, those 

 of 1912-1913 exceptionally high. The course lay from Cape Ann 

 to Cape Sable, thence across the mouth of the Bay of Fundy, and 

 parallel to the coast to Gloucester, besides a station on Jeffreys 

 Bank, and one in the deep basin off Piatt's Bank. 



During the summer, complete oceanographic observations were 

 taken at fifty stations, 165 tows made with the various plankton 

 nets, while the Otter trawl was used at ten stations. 



The plankton collections are much richer than those of 1912, 

 and extremely varied, as might have been expected from the large 

 extent of ocean covered. The trawl hauls revealed a rich bed 

 of the sea scallop, Pecten magellanicus , between the 20 and 40 

 fathom curves, from off Montauk to the latitude of the Chesa- 

 peake. This bed is of considerable commercial importance.
