affected with Acarine disease, the owner is urgently- 

 recommended to destroy them. The bees should be 

 sulphured and afterwards burned ; any stores left should 

 be securely placed beyond the reach of robbers. Money 

 and time spent in feeding and otherwise preparing such 

 bees for winter is wasted. To add driven bees or to 

 unite with a healthy stock means at best only the 

 perpetuation of the disease into the following season. 

 Not only so, stocks suffering in autumn are reduced in 

 numbers and they readily become the victims of robber 

 bees. Robbing bees in such cases run very great risks 

 of contracting the disease. Bees from strong stocks will 

 travel considerable distances to rob weak ones, and this 

 seems to me the most frequent means by which fresh 

 infestations started in autumn are carried over the 

 winter, not in the autumn diseased colony, but in the 

 strong robbing one. 



The colony with, disease well established in autumn 

 should be destroyed. 



Again, in spring, while there may be hopeful circum- 

 stances inducing the beekeeper to nurse colonies which 

 have survived the winter, but in which the presence of 

 Acarine disease is recognised, he should do so only in 

 the most favourable conditions. For example, it may 

 be that he is desirious of saving a young queen who, 

 favourably treated, e.g., under stimulating feeding to 

 the colony, may be induced to quickly build up with 

 young bees. The wintered bees may be expected to die 

 soon, and there is a small chance that the young bees 

 may escape the disease. Apart from this somewhat 

 doubtful possibility, the chances of re-establishment of 

 the colony are so slight as to render its rehabilitation 

 into a strong and profitable stock highly improbable 

 and not worth the trouble. While I am well aware 

 that occasionally such stocks survive, destruction is 

 probably in the wider interests of bee-keeping the better 

 course. 



Preventive Treatment for Diseased Stocks. 



Wherever the introduction to bee hives of acaricides, 

 deterrents, and the like has taken place, serious diffi- 

 culties have been met with. Unfortunately, we cannot
