rich surface haul of Calanus finmarchicus, with a few other copepods, 

 e. g. Centropages, Metridia, Anamalocera, and Euchaeta, besides 

 Meganyctiphanes norvegica, Hyppolyte, Euthemisto, Limacina balea, 

 Sagitta elegans and S. serratodentata, Tomopteris helgolandica, Clione 

 limacina, Pleurobrachia, Phialidium, and agalmid fragments, i. e., 

 the plankton was of the same type as off shore and further west; and 

 rich quantitatively. But when we approached shore, off Moose Peak, 

 our hauls were extremely barren, by far the poorest yet made. The 

 four-foot net, hauled for three quarters of an hour, at Station 33, with 

 an electric light in its mouth, contained only a few Calanus, four 

 medium sized Staurophora, and a few Sagittae, the whole, aside from 

 the large Medusae, being less than 20 cc. in bulk. This was quite 

 the contrary to what we expected, as the northeastern corner of the 

 Gulf and the Bay of Fundy have always been credited with a rich pela- 

 gic life. But in the Grand Manan Channel (Station 34), the plankton 

 was even poorer than at Station 33, the four foot net, hauled from 

 50-0 fathoms, containing almost nothing except a very few Calanus 

 and other small copepods, while a few Staurophora were seen on the 

 surface. And much the same condition was encountered in the mouth 

 of the St. Croix River, where surface tows were made on August 18, 

 very little being taken, or seen, except Staurophora. In Eastport 

 Harbor, however, many Meganyctiphanes, probably attracted by 

 refuse from the sardine factories, were taken on the surface. 



When we returned through Grand Manan Channel, we made a haul 

 off the north end of Campobello Island, where the four-foot net did 

 not bring back even a single copepod; but it yielded large numbers of 

 Balanus eggs in segmentation stages; and a few Staurophora were seen 

 on the surface. Near the entrance of the Channel (Station 35) the 

 water was hardly more productive, the whole catch of the four-foot 

 net (35-0 fathoms), chiefly Calanus and Sagittae, being contained in 

 an ordinary table spoon; while no Medusae or ctenophores were seen 

 on the surface. That night, however, in Cutler Harbor, we found a 

 fairly rich neritic plankton, chiefly copepods, gammarid amphipods, 

 and the hydromedusid Sarsia. When we once more ran off shore to the 

 edge of the deep basin, August 20 (Station 36), the water was occupied 

 by the Calanus swarm, with a few Euthemisto, a few Euchaeta, many 

 Sagitta, chiefly S. elegans, Aglantha , digitale, Beroe cucumis, Mega- 

 nyctiphanes, and Staurophora, i. e., a typical Gulf of Maine plankton 

 in considerable quantity. And the richness of this station and that of 

 Station 32, showed that the edge of the dense Calanus swarm followed 

 the 100 fathom curve, the barren zone being only a narrow coast belt.
