BEE-HOUSES. 



167 



The folding doors behind the bee-house have only to 

 be opened, and the hives are at once exposed to full 

 view ; then, by raising the upper hive or cover, the 

 glasses may be deliberately inspected without molesta- 

 tion from the bees, and the progress made by the 

 busy multitude may be watched from day to day. 

 Under the roof on each side are openings to act as 

 ventilators, to allow the heated air to escape. With the 

 sun shining on the house, and no escape of this kind, 

 the temperature would become that of an oven. 



Here our illustration shows the back view of the bee- 

 house, the interior being furnished with two of our im- 

 proved cottage hives. Two suspended weights balance 

 the top hives which cover the glasses ; the cord for each 

 runs on pulleys, so that the covers can be easily raised
