Dysentery is a disease produced either by long confinement, by dampness, or by feeding in the winter. The first thing bees do when disturbed is to fill themselves with food, so that in winter weather, when they cannot get out to void their fæces, hives should not be meddled with, otherwise the complaint may be brought on. It is also engendered in many instances by the state of the weather in winter months, and is indicated by the yellow colour of the excrement, and by its being voided upon the floors and at the entrance of the hives, which bees in a healthy state generally keep clean. All, that can be done for them when affected is to well clean or to change the floor-board, and so produce cleanliness. Having made some remarks on this disease at page 214, in connection with bees sent to Australia, we will pass on to the more formidable, but happily less common, malady of "foul brood." This disease does not attack the bees themselves, but affects the larvæ, by causing them to putrefy in the cells, thus destroying all hope of the rising generation. Bees are exceedingly fond of their young, and are greatly dispirited when their hives are in this plight. In common with most pestilential disorders, no satisfactory cause is assigned for its first appearance. Some apiarians contend, that "foul brood" is another name for chilled, brood; others, that the queen, by a freak of nature, deposits some of her eggs the wrong way upwards, and that these putrefy in the cells and contaminate the others. Whatever may be the origin, one thing is very certain, "it is catching;" there is, however, in the circumstance of the adult bees and of those about emerging from the cells not being injuriously affected thereby, a great help to its eradication, as will presently be shown. There are two kinds of foul brood--one is moist and fœtid, the other is dry and not contagious, the brood merely drying up in the cells, and, from its partial character, is probably within the power of the bees themselves to overcome. In the former, instead of drying up, the brood remains dark and slimy in the cells, and emits a most unpleasant odour, perceptible at some distance from the hive.
