'Then why did you try to poison him?' Una asked wickedly, and Simon hung his head like a shy child. 'Oh, that was when he set me to make a pudden, for because our cook was hurted. I done my uttermost, but she all fetched adrift like in the bag, an' the more I biled the bits of her, the less she favoured any fashion o' pudden. Moon he chawed and chammed his piece, and Frankie chawed and chammed his'n, and--no words to it--he took me by the ear an' walked me out over the bow-end, an' him an' Moon hove the pudden at me on the bowsprit gub by gub, something cruel hard!' Simon rubbed his hairy cheek.
This is from "Simple Simon" by Kipling.
I am glad if some one teach me the meaning of "I biled the bits of her"
