the Banks of the Lena River. 425 



along- we observed a third flock with forty birds in it. They, 

 too, started running away, and took to the water only when 

 a rifle-ball was unwisely fired amongst them. They dived 

 far and remained for a considerable time under water, 

 the head and upper portion of the neck alone being visible. 

 Although they were much frightened by the steamer 

 passing through their midst, not a sound escaped them. 

 These birds had their wing-quills about half-grown, while 

 their bodies were very lean. In a fourth flock certain of 

 the birds were floating on the water, others were semi- 

 buoyant, but most of them had their necks in part 

 below the water. It is said by sportsmen in Yakutsk that 

 the Geese pass northwards at the end of April, and return 

 by the Sea of Okhotsk on their southern migration. This, 

 I think, Avould be about the middle of August of the 

 present year.]
