450 DISEASES OF BEES. 
method, it has not proved effective in every case, for, since 
the bees and the queen may be contaminated in their or- 
gans (798), the disease, after a time, may reappear. Every 
means should be used to kill all the spores of the bacilli. 
Mr. Cheshire has kept some of them in a glass tube (‘‘ Bees 
and Beekeeping,’’ page 560), and exposed them on several 
occasions to a temperature below frost, and they were alive 
after sixteen and a-half months. Mr. Jones reports having 
kept foul-brood combs exposed a whole winter to a temper- 
ature of 35° below zero, —in Canada, — without succeed- 
ing in killing the spores. (‘‘Gleanings in Bee-Culture,’’ 1884, 
page 767.) 
792. We will now give the method of Hilbert, as prac- 
ticed by Chas. F. Muth and described in his ‘‘ Practical 
Hints:”’ 
“In April, I discovered two colonies in my Apiary, affected 
with the disease. I brimstoned the bees the same evening, 
burned up the combs and frames, and disinfected the hives. 
Another colony showed it in May. Feeling sorry to kill a 
beautiful queen, besides a very strong colony of pure Italians, I 
brushed them on ten frames of comb-foundation, into a clean hive, 
and placed over them a jar with food, as I shall describe hereaf- 
ter. The old combs and frames were burned up, and the hives 
disinfected. This feeding was kept up until all the sheets of 
comb-foundation were built out nicely and filled with brood and 
honey. It was a beautiful colony of bees about four weeks after- 
wards, full of healthy brood, and with combs as regular as can 
only be made by the aid of comb-foundation. Four more colonies 
were discovered infected, one after another. All went through 
the same process, and every one is a healthy colony at present. 
T was so convinced of the completeness of this cure, that I intro- 
duced into one of these colonies my first Cyprian queen sent me 
by friend Dadant. 
“ All are doing finely now, and no more foul-brood. Should, 
however, another one of my colonies show signs of the disease, 
it would not be because it had caught it from its neighbor which 
I had attempted to cure, but because the germ of foul-brood was 
hidden somewhere in the hive, and of late had ‘come in contact 
with a larva.
