Remarks. 



Heavily infected from a cast which up 

 till a few days previously appear 

 healthy. Crawling sudden and ex- 

 tensive. 



An ordinary advanced case. 



See record, No. 60. 



Has shown none of usual signs of Isle of 

 Wight disease, but has dwindled since 

 spring. Queen found free of infection. 



Intermittent signs of disease shown. 

 These bees not known to have the 

 disease. 



Reported 17th September: — "Now 

 very healthy and closely packed down 

 on ten standard frames. Gave one and 

 a half crates shallow frames surplus." 



Same apiary as No. 108. 



Strong stock all along, swarmed twice. 

 Gave two and a half crates shallow 

 frames surplus. Never showed any 

 signs of disease. 



See record, Re No. 1. 



Intermittent disease history from pre- 

 vious September. Died out about 

 this date. 



An ordinary advanced case. 



Do. 

 There have been no signs of the disease. 



Slight crawling only, at this stock. 



Crawling observed for months pre- 

 viously. Infection very heavy. 



Died subsequently of the disease. 



From 4th June onward this stock by 

 repeated examination (4 times in one 

 month) showed practically every bee 

 infected. It appeared to be doing 

 moderately well. Mass crawling was 

 never observed, but the stock became 

 queenless and died out before the 

 end of July, 



Stock believed healthy ; from apiai-y 

 where other four stocks had died 

 from the disease. 



Stock crawling. Drones were included 

 in this examination. 



Not known to be sick, but some bees 

 ' seem to have dislocated wings. 



Yielded a good top swarm, and crawl- 

 ing appeared, subsequently. Tracheae 

 were closely packed with mites in 

 all cases.
