It will be interesting to bee-keepers to learn that, at the apiary 

 of a recognised expert in Norfolk, the fact appears to have been 



Acarine Disease definitely established that Italian queen 

 of Bees provide distinct powers of high resist- 



ance against Acarine disease in those hives 

 in which they are introduced. As is well known, the Ministry 

 has during the last few years supported a scheme to supply bee- 

 keepers with healthy queen bees from the best apiaries in the 

 North of Italy. It is satisfactory to find that as far back as 1912 

 the Norfolk expert referred to introduced Italian queen bees into 

 his apiary, which was at that time seriously attacked by x^carine 

 disease (also known as Isle of Wight Disease) and that the 

 " crawling " stage, usually a sign that the disease is becoming 

 far advanced, was gradually overcome. Since that time, his 

 apiary has been built up until there are 26 stocks in which there 

 is not a sign of Acarine disease. This expert has recommended 

 others in the county to adopt the course which he himself 

 successfully pursued. It is stated that they have done so with 

 wholly satisfactory results.
