You Must nt Swim...

 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!
