GROUP DIVIDED. 
Divide the experimental group into two equal lots. 
Mark a large A on the hives of one lot and B on the hives 
‘of the other lot. Uniformity that could not be obtained 
amongst individual hives can be secured by making the lots 
uniform, having in each the same number of old and young 
queeus, etc. 
Now prepare the colonies of lot B just as you would 
have prepared the whole apairy if you had not heard of co- 
Operative experiments in apiculture. Any change in- your 
management of them will spoil the experiment, as it will not 
give a fair comparison between your way of managing and 
ours. This does not mean that you are to neglect them any 
more than usual. If your method of out-door wintering is 
better than ours, you are requested to prove it by testing the 
two side by side; but if you feel that our way is better you 
‘should risk four hives by the old way to see how much 
better. The colonies of lot A are to be managed according 
to instructions given below.
