"Tak any brid, and put it in a cage, And do al thyn entente and thy corage To fostre it tendrely with mete and drinke, Of alle deyntees that thou canst bithinke, And keep it al-so clenly as thou may; Al-though his cage of gold be never so gay, Yet hath this brid, by twenty thousand fold, Lever in a forest, that is rude and cold, Gon ete wormes and swich wrecchednesse. For ever this brid wol doon his bisinesse To escape out of his cage, if he may; His libertee this brid desireth ay."
