Rudyard Kipling

         You must n't swim till you're six weeks old,
              Or your head will be sunk by your heels;
         And summer gales and Killer Whales
              Are bad for baby seals.


         Are bad for baby seals, dear rat,
              As bad as bad can be;
         But splash and grow strong,
         And you can't be wrong,
              Child of the Open Sea!
