OBSERVATORY BEEHIVE FOR TEMPORARY USE. 83 



this case considerable time elapses (about six 

 weeks) before the progeny of the young queen is 

 added to the population, which, meanwhile, will 

 dimmish somewhat in number, so that results may 

 not prove as satisfactory as by the adoption of 

 the first method. 



There are various ways of mounting observatory 

 hives besides that illustrated in Fig. 69. Fig. 74 

 shows in section a hive swung between pivots, so 

 that it can be turned with either side to the wall. 

 The lower pivot is of wood with a central hole 

 through which the bees pass to the hive, a hole 

 being cut through the supporting block up which 

 the bees may creep. This block comes against the 

 opening cut in the external wall of the room 

 against which the board, to which the whole is 

 fixed, is bolted. The top pivot can be withdrawn 

 so that the hive case may be detached. 



The hive can also be supported on a central 

 pivot as shown in Fig. 75. The foot is cross- 

 shaped, one of the pieces being hollow and form- 

 ing the entrance for the bees. In the interior of 

 the foot immediately below the hollow pivot an 

 incline of wood is placed to guide the bees to the 

 hole that leads into the hive.
