with, and all wood work painted over with the salicylic solu- 

 tion, to prevent the disease spreading any further. 



"If the treatment above given be adopted in time, it will 

 effect a cure, but if the disease is neglected and allowed to as- 

 sume the worst type, much more trouble will be experienced in 

 its eradication. Some advise destroying the hives, but I never 

 found any necessity to do this, as salicylic acid is sufficient to 

 destroy any germs of the disease which may have adhered to 

 the hive." — (British Bee-Keepers' Guide Book.) 



'i'94. Mr. Cheshire, in turn, finding this process of evap- 

 orating salicylic acid long and tedious, contrived a new 

 method in which he uses carbolic acid, otherwise called phenol, 

 after the suggestion of an Irish Apiarist, R. Sproule. 



As bees strongly dislike carbolic acidj since it is used to 

 frighten them (GYO), the quantity has to be very small, or 

 they will not touch the food containing it. The dose used 

 by Cheshire, in the food, is about one ounce for forty pounds 

 of syrup, amounting to l-640th, but this proportion may be 

 changed, according to circumstances. When there is no honey 

 in the fields, he says that the proportion may be reduced to 

 l-750th. 



"The carbolic acid should be added to the syrup when the 

 latter is cool and equally mixed by careful stirring. ' ' — (Cheshire. 

 Page 565.) 



When the bees refused to touch the food thus prepared, 

 Cheshire succeeded in compelling them to use it, by pouring 

 it into the combs, in the cells immediately around and over 

 the brood. He advises the use of one part of phenol in 

 fifty parts of water, for spraying the infected combs that 

 are removed from the bees, but in no case does he spray the 

 inside of the brood-nest of the diseased colony with this 

 solution.— {British Bee Journal, 1887, page 397.) 



A number of other drugs, such as naphtol beta, camphor, 

 oil of eucalyptus, formalin, have been recommended in dif- 

 ferent ways, while some authors hold that drugs are of no 

 avail. Mr. E. R. Root, in the A B C of Bee Culture, says :
