I think we may take it as proved, so far as the evidence goes, that this complaint is an infectious disease spread from hive to hive. The next point I would like to consider that the disease remains confined to them ; in only a few cases have I been able to find that the drones were affected, and in none that the brood showed any signs of it. I have myself opened several hives in which nearly all the workers were dead, and the queen with a few attendants alone remained alive while the brood appeared quite healthy and were emerg- ing from their cells. This fact goes a long Avay towards proving that the disease. MAP SHOWING INFECTED AKE.4S IN GREAT BRITAIN IN 1910. is, how is the disease spread and what is the nature of the infection ?
