[pups] being taken by the sealers while they were still on tr> ice, a large 
red cross was painted on the back of each" (Sivertsen, p. 56). bleven of the 
marked seals were subsequently recovered, eight of them near the tagging site 
within a year after tagging. One which had been tagged on the hind flipper 
with a silver plate was recovered eight years later, rear Spitzbergen. 
(2) Sivertsen mentions briefly that seven young hooded seals were tagged 
in 1932, presumably with the aluminum alloy plates. Only one was recovered, 
13 days after the operation and 400 nautical miles away! 
(3) "Per Hést, a Norwegian naturalist. . . .was out on several of the 
Norwegian vessels operating this spring on the coast of Newfoundland. He 
managed to tag 95 seals with a tail tag similar to that described by Sivertsen" 
(Dean Fisher, letter of May 27, 1949). 

Figure 1Q--Tags used on harp seals in the White Sea, 1928-1932. (a) Tail tag; 
(b) flipper tag. Both silver and aluminum-alloy were used. “The 
two thin needles from the upper-most plate were stuck through the 
skin, in the case of the tail-mark on both sides of the tail-vertebra, 
and fastened to a similar but pierced plate on the underside" 
(Sivertsen 1941:56, fig. 24).
