112 APPENDIX. 



The distinctive advantages of this hive are: First, It 

 gives the apiarist complete control of the queens, without 

 dffeturbing the comb or the working bees. 



Second, It has an entrance capable of such an adjustment 

 by means of a convex lens, that the vapor or breath of the 

 bees will congeal during the coldest weather upon the inner 

 surface, which prevents their escape and consequent destruc- 

 tion until a change of temperature shall remove all danger ; 

 the hive thus regulating itself, according to the state of the 

 weather. 



Third, It is ventilated in such a manner, that the air strikes 

 the glass lining in the summer, and prevents the melting 

 away of the comb. The chambers may also be lined in the 

 same manner, with a ventilator at the top, by which, in winter, 

 the vapors and other exhalations of the bees may fk-eely 

 escape. There is also a false cover, so constructed that a 

 quantity of candy may be arranged for the sustenance of the 

 bees, when a severe winter or other cause shall have reduced 

 the supply of honey. 



Fourth, It is so constructed that the cold air from the ven- 

 tilators cannot directly reach the inside of the hive. 



Fifth, It is so constructed that the bees may cluster in 

 the centre, or pass to any cell within the hive, without tra- 

 versing the outside, or crossing broad ranges of comb, which 

 often saves them, in cold weather, from destruction. 



Sixth, With the aid of these improvements, the dronelj 

 may be removed from the hives with the least amount of 

 trouble.
