Vol, XLIV—No. 13. c Editorial Comments Care in Foul-Brood Regions. Oae of the results o( the New York State investigation gives material for thinking over, and helps to explain some things. A sam- ple of /ica^f/iv/&;'Oorf, taken in a of bees affected with black brood, showed the presence of Bacillus alvei in considerable numbers. For practical purposes it matters little whether the disease in that re- gion was black brood or foul brood, if Bacillus alvei is the culprit in both cases. The point of emphasis is that Bacillus alvei may be pres- ent without being detected by any ordinary means. How can that be i Scientists tell us that formic acid in the form of vapor is con- stantly exhaling from combs out of which young bees have lately emerged, temperature and robustness of the colony favoring such development. Also, that where formic acid is present in suflioient quantity the spores of Bacillus alvei can not germinate. This helps to account for the fresh breaking out of disease at times where it has been supposed to be eradicated, and for the belief of some that care- lessness, chilled brood, etc., may produce the disease. It also accounts for the apparent disappearance of the disease when a colony becomes strong and active in the harvest, only to break out later on. The moral of all this is that in all cases, and especially in regions where disease is present, it is of first imnortance to keep colonies strong and in good condition at all times. The National and Its IncFeasing Work. From a letter recived recently from General Manager France, it seems that the National Bee-Keepers' Association is to be kept very busy with various kinds of trouble for some time. Among the cases on hand and in prospect are the following: A complaint from Colorado about bees causing pear-blight. In New Yor
