The practice of using a knife for cutting out diseased comb and then using the same knife for work amongst healthy comb (which I have seen done) is by no means wise, as the spores may thus be transferred from diseased to healthy hives. Cowan (4) observes that beekeepers who have not succeeded with their bees in consequence of foul brood have been kno-n to sell by auction hives in which the bees have died.

Treatment by chemicals: (a) by feeding chemicals in food; (b) by putting certain chemical substances into the hive and allowing them to evaporate at the temperature of the hive. This latter method may be regarded as rather prevent...
