 disease the apiarist should at once take steps necessary to prevent its spread 

 and then forward a sample of the brood to the Department of A^-riculture 

 for examination. 



(4) Offensive Glue-pot Odovr.— This odour is very easily noticed when 

 foul brood is in an advanced stage; otherwise, it can rarely be noticed. 

 Bee-farmers should not, therefore, entirely depend upon the odour as a 

 means to diagnosis, but should study all the symptoms, so that the disease 

 may be detected before it reaches the advanced stage.

infected comb is so held that light shines down the cells. To avoid the risk 

 of having contagious matter such as combs that contain foul brood in this 

 stage, beginners especially should attend to and immediately examine any 

 hive that bees have deserted, or where bees have died out. Extreme care 

 should also be taken to see that any suspicious material and any purchased 

 material coming from an unknown source is thoroughly disinfected by 

 boiling'. 



If the apiarist is observant and takes notice of the foregoing symptoms, 

 any chance of confusing the disease with such conditions as chilled, starved, 

 or ovei'-heated brood should be practically eliminated. In the three conditions 

 mentioned the dead larvae are not diseased, and are usually of a dark-grey 

 colour. iSTeither is the ropy characteristic present, and although there may 

 in severe cases be a sour smell from the dead matter, the odour is not of the 

 offensive glue- pot type.
