VENTII.ATION. 93 



The pallid cheek or hectic flush, the angular form and 

 distorted spme, 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 UBfavorably Avith 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.

 devise some simple, cheap, and efficacious way of furnish- 

 ing a copious supply of pure air for our private dwellings, 

 pubKc buildings, and travelling conveyances, wiU be a 

 greater benefactor than a Jenner or a Watt, a Pulton 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 tis pariter apibus metuenda." 



" Extremes of heat or cold, alike are hurtful to the bees." 



To be useful to the majority of bee-keepers, artificial 

 ventilation must be simjsle, and not as in Nutt's hive, aij^d

 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 cqmpelled to adopt, when the openings 

 into their hoUow trees are so small, that they must employ
