FOURTH ANNUAL REPORT 



photographed, but to take the picture from the rear. I 

 wanted to show how to look down in the comb. As an illus- 

 tration we will suppose this to be a comb of foul brood, and 

 I want to look into it and there is the light — and by the way, 

 never take candle light or electric light — you want good day 

 light in order to see it satisfactorily. If I were to hold it 

 upright, and stand with the light coming over my shoulder, 

 I would still look down into the bottom of the cell and see 

 no foul brood. But let me tip the top towards me so that

my eye looking in there will strike the lower side-wall about 

 one-third the length towards the base, then I will see those 

 black-brown heads readily all through the comb. You need 

 never question it. Black brood or pickled brood will never 

 have the appearance that foul brood does. In every state 

 where I have found it, there is a marked difference. This 

 photo is simply showing where I am holding up the comb. 

 I made a streak on the negative showing the angle of the 

 rays of light. It should be coming over the shoulder, and 

 then tip the top of the comb towards you.
