On June 28 several tagged pups were seen on land and on July 18 one was seen 
in the surf, 
(2) In 1947 we visited the Northeast Point sea-lion rookery and continued 
our experiments with ear tagging: 
June 9; 26 pups tagged; serial nos. 10,078 to 10,107 inclusive, of which 
four tags failed to clinch. 
July 2; 50 pups tagged; serial nos. 10,108 to 10,157 inclusive, 
We made the June visit a few days too late for best results, The lis 
were belligerent and would not allow us to approach the center of the rookery. 
The July visit was more timely, All of the cows and all but a few of the bulls 
fled to the water as we approached. On this visit we noted several sea~-lion 
pups wearing the tags which we had applied three weeks earlier; also several 
pups from whose ears the tags had been lost, 
On July 22, native workmen killed five sea-lion pups for food. They 
were able to kill only these five, since all of the other rookery animals, 
pups included, had taken.to the water. One of the five carried an ear tag 
applied three weeks earlier, The ear was swollen; the flesh had grown partly 
over the base of the tag and was slightly raw. We picked 26 lice from the hair 
at the base of the ear. 
Up to the time of writing (1949) we have recovered no sea-lions bearing 
evidence of having been tagged. As a result of a previous study (Scheffer 
1945) and our experiances in 1946 and 1947, we tentatively conclude that ear 
tags are unsatisfactory. They are difficult to apply and they probably do 
not remain on for more than a few weeks, We shall have more definite ideas 
on this matter when we have opportunity to examine the ears of sea-lions 
killed at Northeast Point during the coming seasons, 
If sea-lion pups are to be marked, we suggest that the best times for 
handling them are the first week in June, before the height of the mating 
season, and the first week in July, after the mating season and before the 
pups are taking to the water. 
sa perp seal (Phoca groenlandica) and hooded seal (Cystophora 
cristata), te Sea,--Migration studies of the harp seal and the hooded seal 
were efrec means of tagging experiments in the White Sea (Sivertsen 
19413 54-61; aA 1943: 89). 
(1) Between 1928 and 1932, Norwegian biologists tagged 171 harp seal 
pups. he first year, they applied silver tags of three types to the fore 
flipper, hind flipper, and tail, finally concluding that a tag on the teil 
was best. In later years, they developed tags of aluminum alloy which were 
forced through the skin and fastened by paired wires (fig. ). "This method 
of marking was very humane; most of the young seals did not react at all dur- 
ing the experiment. In order to avoid the risk of the marked White-coats
