Premise: Never again did the swans become men ; but they are still different from other swans , for in the night-time those who listen can hear them talk in a language that is certainly not swan 's language ; and there are even sounds of laughing and talking , unlike any noise made by the swans whom we know .<br>The little Bunyip was carried home by its mother , and after that the waters sank back to their own channels .<br>The side of the pool where she lives is always shunned by everyone , as nobody knows when she may suddenly put out her head and draw him into her mighty jaws .
Hypothesis: they are the same as other swans.
