Why does the Cavlier slip off the Baron's land occasionally and how does Cosimo help him?

The Cavalier has obtained permission from obliging farmers in the area to keep bees on their properties, and so sneaks off to tend his charges there instead of on the Baron's land, as the Baron entertains an irrational fear of being stung. Cosimo watches with great interest, and even offers his help one day when the bees are swarming. The Cavalier instructs him to climb a certain pomegranate to which they are all headed, and wait for his signal. When he gives it, Cosimo bounces the tree ever so slightly, and the bees drop into a box the Cavalier has prepared below them. Thus, they are captured and the Cavalier's next season is prepared.
