I Estimates have been worked out, insofar as possible, to show the approximate number of seals of each 

 class which should be credited to each island. Seals do not, however, haul out in accordance with figures 

 given. Seals born on either island frequent the other island. They travel promi.scuously between and 

 haul out on either of the 2 islands. The total for both islands, however, is appro.\imately correct.
