have been introduced here, with that filthy, loath- 
some, and worst of all trees, the Lombardy poplar. 
Be that as it may, we have it, and are always likely 
to have it, in greater or less number. Thousands 
of stocks of bees are destroyed by this little insect 
in our country annually. The bee moth has be- 
come so common in New England and the middle 
and western States, and its success in destroying 
the bee so complete, that very many apiarians 
have become discouraged, and abandoned the en- 
terprise. Much time and money has been spent 
in devising some plan of destroying the bee moth, 
and of exterminating its race. But it is generally 
conceded that the moth cannot be exterminated, as 
it is not confined exclusively to our apiaries, but is 
found among bees in cavities of rocks and trees, 
and sometimes in the nests of the humblebee. 
Since the extermination of the race cannot be ef- 
fected, the only alternative for apiarians, is to use 
every exertion in their power to prevent its rava- 
ges. This may be effected by using the Self-pro- 
tecting Hive. 
The double inclined plane at the base of the 
hive, is undoubtedly the best possible plan of se- 
curing the bees against the ravages of the moth, 
without interfering with the natural course of the 
bee. Many plans have been adopted by apiarians 
to prevent this loathsome insect from destroying 
their favorite. But all, except the base of the 
Self-protecting Hive, have either failed to accom- 
plish the object of its originator, or interfered 
with the natural course of the bee. Some have 
adopted the use of large hives, situated within 
their dwellings, with the base of the hive some 
distance below the bees, with the design for apia- 
rians to brush out the worms, when they shall 
have been thrown down by the bees. But this
