VENTILATION.

The pallid cheek or hectic flush, the angular form and 
distorted spine, the enfeebled appearance of so large a por- 
tion of our women, who, to use the lauguage of the 
lamented Downing, “ in the signs of physical health, com- 
pare most unfavorably with all but the absolutely starving 
classes in Europe;” all these indications of debility, to 
say nothing of their care-worn faces and premature 
wrinkles, proclaim our violation of God’s physical laws, 
and the dreadful penalty with which He is visiting our 
transgressions. 
The man who shall convince the masses of the impor- 
tance of ventilation, and whose inventive mind shall 
devise some simple, cheap, and efficacious way of furnish- 
ing a copious supply of pure air for our private dwellings, 
public buildings, and travelling conveyances, will be a 
greater benefactor than a Jenner or a Watt, a Fulton or 
a Morse. 
In the ventilation of my hive, I have endeavored, as far 
as possible, to meet the necessities of the bees, under all 
the varying circumstances to which they are exposed in 
our uncertain climate, whose severe extremes of tempera- 
ture forcibly impress upon the bee-keeper, the maxim of 
Virgil, 
“ Utraque vis pnritci' apibus nictucnda. 
“ Extremes of heat or cold, alike are hurtful to the bees.” 
To be useful to the majority of bee-keepers, artificial 
ventilation must be simple, and not as in Nutt’s hive, and 
other labored contrivances, so complicated as to require 
almost as close supervision as a hot-bed or green- 
house. 
By furnishing ventilation independent of the entrance, 
we may improve upon the method which bees, in a state of 
nature, are often compelled to adopt, when the openings 
into their hollow trees are so small, that they must employ
