498 ACCOUNT OF THE ARCTIC REGIONS, 



" Being of a gregarious disposition, tlie main body 

 of the drove follows the leading whales, as a flock of 

 sheep follows the wedders. This disposition is well 

 known by the natives of Shetland and Orkney, and 

 improved to their advantage ; for, whenever they are 

 enabled to guide the leaders into a bay, they sel- 

 dom fail likewise to capture a considerable number 

 of the followers *." From the property of following 

 a leader, this animal is called, in Shetland, the 

 Ca'ing Whale ; and, for the same reason, Dr Traill 

 suggests the name of Deductor. 



There is a considerable similarity between this ani- 

 mal and the grampus ; but there are also such 

 marked and essential differences between the de- 

 ductor and the grampus, or indeed any other ani- 

 mal mentioned in systems of zoology, that it is con- 

 sidered both by JNIr Neill and Dr Traill as belong- 

 ing to no species yet described. 



Of these cetacea, many herds have, at different 

 periods, been driven on shore in Orkney, Shetland, 

 Feroe, Iceland, &c. In a small volume, containing 

 an account of the Feroe Islands f , which was put 

 into my hands by Dr Traill, is a description of the 

 method of capturing the deductor, as practised by 

 the natives of Feroe in the 17th century. From 



* Neill's Tour, &c.
