It happened that a Countryman was sowing some hemp
seeds in a field where a Swallow and some other birds were
hopping about picking up their food. ‘Beware of that man,’
quoth the Swallow. ‘Why, what is he doing?’ said the others.
‘That is hemp seed he is sowing; be careful to pick up every
one of the seeds, or else you will repent it.’ The birds paid
no heed to the Swallow’s words, and by and by the hemp
grew up and was made into cord, and of the cords nets were
made, and many a bird that had despised the Swallow’s advice
was caught in nets made out of that very hemp. ‘What
did I tell you?’ said the Swallow.
Destroy the seed of evil, or it will grow up to your ruin.
