How's that for an unusual subject? Yesterday while sweating through my veil over a hive, I was absolutley delighted to receive a cool breeze to refresh me. I was realy surprised by how cool and constant the airflow was. I was standing beside the hive, looking into a super and there were a bunch of ventilating bees along the wall of the hive, pumping air upward. I have heard that the bees will sometimes pump air up on one side and down on the other side of the supers.
