hourly for twelve hours, thus covering an entire tide, both ebb 
and flood. We ran a section across the coastal shelf normal to the 
coast opposite Shelburne, and another partial one opposite Halifax, 
with special attention to the enclosed sinks which characterize 
this region. 
The European war prevented a continuation of the work east 
of Halifax; and the time remaining was devoted to the Gulf of 
Maine, where the stations of the preceding years were repeated; 
and also to a section from Marthas Vineyard to the Gulf Stream, 
where two sets of the long trawl were made for tile-fish (Lopho- 
latilus chamaeleonticeps), which proved to be present in its usual 
abundance. 
During the summer, complete oceanographic observations were 
taken at 52 stations; 126 tows made with the horizontal plankton 
nets, and the quantitative net was used at 26 stations. No bot- 
tom trawling or dredging was done. 
The plankton collections, though quantitatively as rich as those 
of 1913, were much more monotonous, as might be expected from 
the fact that most of our work was done in Boreal water. They 
are especially rich in copepods, amphipods, and Sagittae.
