'BEE' zer

It's that time of year again in the orchard, the bees are swarming. Iknow very little about bees I have to confess, however, the farmer puts the bell shaped contraption over the swarm (when it has settled) and gradually lowers it over a space of hours and days. The bees gradually go up and the bell comes down. When the bees are in the bell he takes the bell puts it on top of an empty hive gives it a sharp 'whack' and the bees drop down into the hive. Voila!!
Lesson over.
