Practical Queen Production In the North. by Carl A. Jurica Ph.D.
I was tempted to copy the full chapter but as the book's in print and the now ageing author is trying to raise some income from it I've decided not to. There's some thought provoking ideas in this little book which carries a 1985 copyright.
