A STUDY IN " ISLE OF ; [9104] With regard to Mr. Crawshaw's reference (p. 366) to my letter (p. 295), I did not suggest that all cases of swarms manifesting " Isle of Wight" were due to visits of scout bees to empty diseased hives. I suggested that of three swarms which showed " Isle of Wight " last summer, two of them got the disease through being hived in contaminated hives; but the other having been hived in a brand new hive, I hit upon the activity of scout bees as a likely explanation. Anyone who has observed bees engaged in "scout" work will, I think, admit that if, after a scourge of " Isle of Wight/' the empty hives harbour spores of Nosema apis, at least a few of the scout bees, by their frequent visits to hives, must come into dangerous contact with the disease. Assuming that a stock on the point of swarming is perfectly healthy and that a dozen of its scout bees have, by their visits to an empty hive, become infested by the parasite, the whole of the in- fested scout bees would not be likely to join the swarm, as some of them would probably be visiting the empty hive at the time the swarm issued, and would not be able to join it. Thus some of the scout bees Avould remain with the stock, and both stock and swarm would have the disease in their midst. As most of the scout bees would join the swarm, it would show signs of the disease sooner than the stock. Therefore the stock could not be expected to show immunity, unless
