sky witli a, roar of wings. On the pond they are, in the presence 

 of live decoys at least, very restless, continually making short 

 unexpected nights, only to return to the same spot. During the 

 best year, 29 were secured, and another year 22. They have oc- 

 curred eight out of the ten years, and 82 specimens have been taken. 

 They are of course rare here as compared with ponds on the south 

 shore of Martha's Vineyard. 



Canvas-back (Marila vallisineria). This species has occurred 

 as follows: one on November 13, 1902; 5 on November 4, 1905, 

 and two on November 3, 1909. One other individual was iden- 

 tified through a glass, but this completes the list. It was a curious 

 coincidence that on the morning of November 4, 1905, three Canvas- 

 backs came to the decoys before it was light, and at 2:30 p. M. 

 of the same day a pair was taken . 



Scaup (Marila marila and .1/. atfuiis). These two species have 

 been bunched in the records, so that it is not possible to separate 

 them. During the last three seasons, however, and in 1904, count 

 has been kept, and places the Greater Scaup at about 20 per cent 

 of the number for the two combined species. The Scaups repre- 

 sent 13 per cent of the entire bag for the ten years. The Lesser 

 appears at times in flocks of 12 to 25, while the large Scaup are 

 often single, or three or four together. Nearly every flock of 

 Redheads has had at least one or two Scaup among them. Scaup 

 appear scattered along in the records late into November, and my 

 earliest for the lake is September 18, 1904 (M. marila). The 

 next earliest is October 4, 1900 (species not stated). Their ap- 

 pearance between the 8th and 12th of October is regular enough to 

 be depended upon, and only once are they recorded as late as Octo- 

 ber 18. 



Ring-necked Duck (Marila collaris). It is possible that some 

 of these may have passed as common Scaups, as I did not see all 

 the birds as they were taken. I am sure, however, that only a few 

 could have got by in this way. The records show three specimens: 

 one each on October 9 and 26, 1907, and one on October 13, 1908. 



Golden-eye (Clangula clangula americana). A very common 

 bird in the pond late in November, and always tending to become 

 local at that time of the year, moving back and forth to the salt- 

 water with the regularity of clock-work, but never, so far as I am
