defects should be remedied whenever observed, but meanwhile, if legiti- 
mate fieldwork is likely to be interrupted, every colony should be 
assisted in protecting itself against assault by having its hive made 
secure and the entrance such a narrow pass as to enable a few workers 
to repel attack there. 
Should robbers get well started before being observed, the entrance 
of the hive should be narrowed at once, and wet grass or weeds may be 
thrown loosely over it, or a pane of glass may be stood against the 
front of the hive in a slanting manner to confuse the intruders. In 
extreme cases the attacked colonies may be removed to a cellar for a 
few days, plenty of ventilation being given during confinement, and 
a new location, apart from other colonies, selected, on which they are 
to be placed just at nightfall; or, instead of putting them in the cellar, 
they may be taken a mile or more away and returned only when the 
danger has passed. With these precautions, little loss is to be feared 
on this score. 
In general the intelligent owner who gives careful attention to cer- 
tain important points in bee management finds that he very rarely has 
disease to contend with, and that the reduction of profits through the 
depredations of bee enemies is not, in most parts of the Union, a seri- 
ous discouragement. Altogether it seems to the writer that the risks in 
these directions are even less in bee keeping than those usually met 
in the keeping of other animals, which, like bees, are legitimately made 
to contribute to the wealth of the individual and of the nation.
