Blessings for Nos Galon Mai - the growing time

'Oh, do not tell the priest our plight, or he would call it a sin,
But we've been out in the woods all night, a-conjuring summer in,
And we bring you good news by word of mouth, good news for cattle
    and corn
Now is the sun come up from the south, by Oak, and Ash, and
    Thorn.'
