52 MONTANA EXPERIMENT STATION 
ily applied lubricant. The sheets may have a tendency to stick to. 
one of the rollers. To prevent rolling back, the edge must be start- 
ed and to prevent tearing, a clamp should be used pulling on the sheet 
across its whole width. The sheets may then be trimmed and be- 
fore storing away should preferably have thin tissue paper placed 
between them to prevent sticking. , 
It will be seen that where any number of colonies are kept, to 
house the various implements and to store empty hives and surplus 
combs, some sort of a shop is desirable, and preferably a honey 
room alsw. In storing away combs it is essential that they be plac- 
ed where mice cannot get at them, as mice are very. fond of honey. 
Also proximity to ants is a nuisance. The greatest enemy to 
combs are the larvae of the wax moth. There are two species of 
moths which lay their eggs about bee hives and combs. They are 
of a dull gray color one a little larger than the other, and should 
be destroyed when found about the hives. The larvae feed upon the 
wax and spin their cocoons out of wood fibre on the edge of frames 
cr in the crevices of the hives. Fortunately this pest is rarely if 
ever found in this state, and precaution should be taken not to in- 
troduce it with shipments of bees. Should combs become infested 
or be liable of infection, they may be fumigated with bi-sulphide of 
carbon. This may be done by tiering up the stories filled with. 
combs and then placing the chemical in a can in an empty story 
at the top, when the fumes will settle down and destroy all the 
larvae if there be any. After this the combs may be stored safely 
away until spring when they should be put under the protection of 
the bees as soon as possible. No fire should be used about bi-sul- 
phide of carbon as it is very inflammable and mildly explosive. 
MODES OF WINTERING 
Since much that is to follow in regard to the spring and sum- 
mer manipulation and management of bees, is based upon the as- 
sumption of successful passage of the winter, we will hasten to dis- 
cuss this—one of the most important problems in our state, and. 
one which has received careful attention for several winters past in 
the experimental work of the Station. The results presented in: 
these succeeding pages were obtained from or verified by experi- 
ments conducted during the winters of 1901-02, 02-03, 03-04,’ and.
