FOUL BROOD. 5 
larvae, while extended, have a more or less rounded shape, with the 
segmentation of the body well marked. 
*“The brood dies after the time of capping. The dead larvae are 
therefore almost always found extended lengthwise in the cells and ly- 
ing with the dorsal side against the lower wall. It is not unusual to 
find many larvae dead of this disease in uncapped cells.” 
“Such brood, however, had been uncapped by the bees after it died. 
In this disease the cappings are frequently punctured by the bees. Oc- 
casionally a capping has a hole through it, indicating that the capping 
itself had never been completed. <A larva dead of this disease loses 
its normal color and assumes at first a slightly yellowish tint. “Brown” 
is the most characteristic appearance assumed by the larva during its 
decay.” 
TREATMENT, 
It is not usually necessary to treat a colony for Sacbrood, if how- 
ever the disease is serious enough to weaken the colony then it should 
be treated at once, using the same treatment as that used for American 
foul-brood. 
Sacbrood® seld®m becomes epidemic but it will spread through the 
apiary if bee-keeper should change frames of brood and honey from 
an infected colony to a healthy one. Bee-keepers should never inter- 
change frames from one colony to another unless certain that no dis- 
ease exists. 
ADDENDA. 
1. Weak colonies and failure to swarm during the Spee season, 
should be regarded with suspicion. Look for the cause. 
2. The presence of wax-moth (millers) should always be looked 
upon with suspicion, they cannot cause disease, but if they are at all 
numerous there is something wrong that should be investigated. 
3. Render the old combs from treated colonies at once, wax-moth will 
soon destroy them if not cared for. The average hive contains’ two 
pounds of wax. 
4. Always examine the brood-chamber of every colony, thoroughly, at 
least twice a year. It will be a good investment. 
5. If you have only one or two diseased colonies in a large apiary, it 
may pay you to destroy them entirely and save further loss. 
6. Never feed honey back to bees unless certain that no disease exists 
in your apiary or near you. 
7. Don’t be afraid to make use of your Inspector of Apiaries, he 
is here to help you.
