ITINERARY. 
OcEANOGRAPHIC and plankton studies were carried on by the Gram- 
pus during the summer of 1913 from Nova Scotia to Chesapeake Bay. 
The success of the cruise was largely due to the skill with which Mr. 
W. W. Welsh, of the Bureau of Fisheries, handled the oceanographic 
apparatus. It is a pleasure to acknowledge the assistance of Dr. 
C. O. Esterly for identifying the copepods; Dr. H. J. Hansen the 
schizopods; Dr. C. McLean Fraser the hydroids; Mr. W. F. Clapp 
the heteropods, pteropods, and Salpae, and to Capt. John McFarland 
of the schooner Victor for taking tows and water-samples. 
We sailed southward from Gloucester on July 7; occupied the first 
station off Cape Cod, and then ran across the northwest part of 
Georges Bank to Nantucket light-ship, to commence the first line 
to the Gulf Stream. Some thirty miles southward from the light-ship, 
floating patches of Gulf weed, and the brilliant blue color of the 
water showed that we were approaching the Stream; but the sea 
and wind were rising so rapidly meanwhile, that we made the station 
at the outer edge of the shelf. And even as it was, the nets were 
badly torn, though water-bottles and thermometers were handled 
successfully. The wind continued to rise during the afternoon and 
evening, and by the time we had sailed northward again as far as the 
40 fathom curve, there was a very heavy sea running. Nevertheless 
_ by using a hemp rope, instead of the wire, for the large plankton net, 
the work (Station 10062) was carried out without mishap. 
From Station 10062 we turned off shore again, occupying the 
second Gulf Stream station 80 miles south of Montauk Point, at the 
500 fathom curve.
