the water. A table spoonful of salt should be thrown 
into it once a week, and poultry must be excluded from 
drinking from it. The additional profit will pay for 
this work. 
VENTILATION OF HIVES. 
Ventilation is indispensable to every bee-hive, and if 
it is not supplied by artificial means, it is effected by 
the bees with very great labor and loss of time. If a 
strong colony is examined on a warm day, a large num- 
ber of bees can be seen with head turned toward the 
hive, fanning cool air into it with their wings; another 
large number can also be found inside the hive, fan- 
ning out the impure air, and when these laborers are 
tired they are relieved by others. That such duties ate 
extremely laborious and exhaustive of the strength of 
the bees, is evident without further demonstration, and 
instead of allowing the bees to perform this labor, the 
hive must be ventilated by artificial means , the bee- 
keeper will receive his reward in a large increase of 
honey, as all those bees wfitich would otherwise be en- 
gaged in ventilating the hive will turn their attention 
to honey gathering. 
In warm weather, nearly one-hall of the bees will 
cluster outside on some hives, spending their time in 
idleness, being forced to do so by a suffocating heat in 
the hive, which they are not able to remove with all
