kooed emis u-ah,' meaning by this that they had 'seen many.' 

 They gave the duck the name 'Argly' and told me in the spring 

 I could get many, also their eggs, at the head of our own bay. 

 I was disappointed when the spring came to have my Labrador 

 Duck materialize in the form of the Long-tailed Duck, which 

 sure enough was very plentiful at the head of the bay. 



"In August, 1892 (the latter part, I believe), on our way home 

 we touched at Godthaab, the largest town in Greenland. Here 

 we were entertained by Herr Anderson, the Danish Inspector 

 of South Greenland, an accomplished naturalist, and at his 

 house I had the pleasure of inspecting one of the finest collec- 

 tions of Arctic birds I have ever seen. I showed him my little 

 pamphlet on the Labrador Duck, and also presented it to him 

 on my departure. He told me that his collection represented 

 twenty years' work, and all the hunters in South Greenland 

 (some 500 men) had instructions to bring to him any strange 

 birds that they might get. In this way he lias added to his 

 collection from time to time many rare birds and eggs. In all 

 this time he claims to have heard nothing of the Labrador 

 Duck, which I consider is substantial proof that within the last 

 twenty years the Labrador Duck has not visited Greenland. 

 From Godthaab we came directly home to Philadelphia, and 

 this ended my ineffectual attempts at learning something more 

 definite regarding this species."
