216 DISEASES AND ENEMIES OF BEES. 
Contract the entrance of this according to the number of 
bees to pass. If the colony is strong, no danger need be 
apprehended. When a hive has been removed, if the ad- 
joining one is weak, take that in also, to be returned as 
soon as the robbers will allow it. If a second attack is 
made, put the hives in again, and let them remain until 
the marauders cease their attempts. When robbers are 
endeavoring to effect an entrance into a hive, a little 
grass, or what is better, some asparagus tops, thrown 
loosely before the opening, will afford material hindrance, 
and when the attack ceases, it may be removed.” 
I may add to these suggestions that when stocks are 
put in the cellar for protection, they may be entirely des- 
titute of stores, which deficiency must be supplied by 
feeding.

DISEASES AND ENEMIES OF BEES. 
DYSENTERY. 
If proper conditions for wintering be observed, this dis- 
ease need not be feared. If honey is gathered late in the 
season, or is fed so late as not to be sealed up, it will tend 
to produce dysentery. A cold, damp cellar, where bees 
are unable to properly evaporate the moisture in their food, 
and undue disturbance, will also have the same tendency. 
A genuine case of dysentery can be produced in a very 
short time by combining these conditions. It may be de- 
tected by the soiling of the hive about the entrance. The 
combs will also often be soiled and injured. The bodies 
of bees thus affected will be found to be unusually dis- 
tended. When in this condition they should be allowed 
to fly, on the first favorable opportunity, in order that
