The Serpent and the File

: Aesop's Fables

A Serpent in the course of its wanderings came into an

armourer's shop. As he glided over the floor he felt his skin

pricked by a file lying there. In a rage he turned round upon it

and tried to dart his fangs into it; but he could do no harm to

heavy iron and had soon to give over his wrath.

It is useless attacking the insensible.
