Where foul brood exists or where Its existence is suspected 

 it is of prime importance that one have the ability to distin- 



and nose, and Riving attention, need be in any doubt in regard 

 to its presence. 



The one crucial test Is the color and consistency of the 

 dead larva; affected with the disease before It dries up. At 

 this stage the matter of the dead larvie Is always viscid or

 weakened stage the dead matter is slightly less viscid, but a 

 better test is that it Is paler in color. The dead matter in the

 the color Is perceptibly lighter. To determine the consitency
