and its Economic Management. 123 
times over—it is interesting to find that Journal publishing 
the facts of M. Wimel’s success in following my plan. 
In the next number of the same Journal Mr. Crawshaw, 
then “almost convinced,” said, “Here is strong evidence 
that disease may be controlled, if not actually cured, by 
systematic re-queening.” 
It is because this “ great truth ” is of such vast importance 
to the bee-keeping community, and is equally applicable in 
ensuring renewed vitality as the first element in the cure of 
the Isle of Wight disease, that I have shown how my 
position has at last been vindicated. 
Failures. 
As some bee-keepers have failed to effect permanent 
cures by the methods advocated, I find it necessary to 
give a few cautions. For instance, where the outer combs 
have not been used for breeding, or the bees may not have 
crowded on them, they have not undergone a thoroughly 
renovating process. This should be evident to any practical’ 
bee-keeper, and all combs should be exchanged so that 
each one goes through the brood nest while the young 
queen is doing her best. ‘ 
Disease Reappearing in Spring. 
Why does foul brood sometimes reappear in Spring? 
In addition to the above reason, the reader may have 
noticed that as soon as his bees become active under the 
influence of bright weather, they begin to clear out any 
dirty corner, or accumulated rubbish they find about the 
floor. 
This is just where any lurking germs of disease may be 
hidden, and it points to the necessity of exchanging or 
thoroughly cleansing all hives if one wishes his bees to 
remain free-from disease.
