Make me no vows of constancy, dear friend,

           To love me, though I die, thy whole life long,

           And love no other till thy days shall end;

That Water grows

His Sands suffice

But let him once suspect

That Caspian Fact

Sahara dies


Utmost is relative —

Have not or Have

Adjacent sums
