270 TH. BEE-KEEPER’S MANUAL. 
put acid in all the food I prepare. I examined six of 
my hives, and all were healthy but one, and that I 
thought was also healthy. It was an early swarm. 
This year I had thrown off a swarm and a cast, and 
had given me six small one-pound sections nicely 
filled. I looked on the ten frames and found no 
queen and no brood. There was one cell covered 
but not punctured, but I at once recognised it as 
a foul-broody one. Now, the hive had not been 
queenless very long, as about ten days ago I saw 
the queen, and aliioust she was not laying, there was 
a small quantity of brood hatching out, and all did 
hatch out except this one cell. It was uncapped and 
injected with the solution, and the other combs 
and bees sprayed with it. I have no doubt it will 
prevent its spreading in the future, as I shall not 
hesitate in using these combs in uniting if I require 
them. 
‘“‘T have examined six hives to-day, fearing to find 
foul brood, but have not detected a single cell in any 
of the other hives. Now, how did this appear? It 
seems to me probable that it was brought there by 
some of the bees from outside, or a spore might 
have been lurking in some of the corners of the hive 
and had escaped the solution. This proves to me 
that it is impossible to tell when it may break out 
in an apiary; and as we know from experience that 
salicylic acid destroys the spores, I think it not only 
beneficial but important that a certain quantity of 
this acid should be in all the food given to the bees. 
Two years ago I tried feeding the bees on syrup 
containing a strong dose of acid, without spraying
