1917-] in the North Sea and North Atlantic Ocean. 31 



10 Avgust. Sunny; light breeze S.-S.W. 58° 5' N., 

 1° 01' E. 

 Ilerring-Gulls {Lanis argentatus) and Lesser Black- 

 backed Gulls {Larus fuscus affinis) were numerous iu our 

 wake all day. Three Gannets [Sula bassana), one of which 

 was immature, followed the ship for two hours. A few 

 Fulmars {Fulmarus glacialis) and Razorbills {Alca tor da) 

 were seen at a distance. 



15 August. Sunny ; light airs N.E.-N.W. 58° 20' N., 

 2° 15' E. 

 Numerous Razorbills with young were passed. The 

 hoarse croaking calls of the pareut birds and the musical 

 whistling answers of the young ones were frequently heard 

 as they dived in alarm at the approach of the ship. In no 

 case have I seen a young Razorbill at sea attended by more 

 than one of its parents. Four or five Fulmars followed us 

 all day. 



24 August. Sunny and calm. Cromarty Firth. 



Hundreds of Herring-Gulls, and smaller numbers of 

 Lesser Black-backed Gulls and Black-headed Gulls {Larus 

 ridibundus) were seen in the Firth. There were also a few 

 full-grown young Herring-Gulls of the year, which were 

 conspicuous by their curious crouching attitude in the 

 water and by their clumsy, tentative flights. 



26 August. Foggy, with intervals of sunshine ; light airs 

 S.E.-S.W. 58° 1' N., 2° 47' E. 

 The surface of the sea for many miles teemed with 

 Razorbills and their young, and, even at night, we fre- 

 quently heard their hoarse cries followed by the sleepy 

 notes of the baby birds. A Wheatear (CEnanthe oenanthe)^ 

 somewhat exhausted, appeared on board in the afternoon, 

 150 miles from land. 



1 September. Calm ; some rain ; light airs S.W.-S. 

 58° 15' N., 1° 44' W. 

 Great numbers of Fulmars were seen from time to time 

 in companies of five to twenty, while many followed in 

 our wake.
