184 BRITISH BIRDS. [vol x. 



said to belong to that species. Another interesting 

 piece of information, obtained from a duck farmer at 

 Myvatn, was to the effect that in a district some forty 

 miles from " anywhere " three species of Greese bred in 

 such numbers that two men, working night and day 

 took over a thousand eggs ! The reason that they had 

 to be so busy was that the nesting season being in May, 

 at which time there is no grass for the ponies, they have 

 to carry all provisions with them and make a dash for 

 it. This duck farmer, (who had been there himself) 

 knows the birds well and was sure there were three 

 kinds. The Grey Lag he would know as he showed us 

 a nest ; White-fronted he understood from our descrip- 

 tion : the third he said was smaller and anight turn out 

 to be the Pink-footed Goose. I hope some day to 

 explore this district personally, but it is a bad place to 

 get to at that time of year and there are many awkward 

 rivers to cross.
