ARTIFICIAL S WARMING.' 191 



this name when speaking of more than one nucleus and 

 _Z" 1 , II 1 represent them when each has a queen; I 2 , II 2 , 

 when each has raised its second queen ; I 3 , II 3 , when each 

 has its third, and so on, it being always understood that 

 7", II, without the small numbers above them, indicate that 

 the nuclei are at that time rearing queens. The first 

 nucleus will be formed May 10th, and the second May 20th.

As it may often be desirable to remove the queen of a 

 nucleus, before she has begun to lay eggs, if her colony is 

 supplied with a sealed royal cell from- another nucleus, no 

 time will be lost, and much trouble saved. 



The following, from the pen of Rev. Mr. Kleine, one 

 of the ablest German Apiarians, will be interesting in this 

 connection : " Dzierzon recently intimated that, as Huber, 

 by introducing some royal jelly into cells containing 

 worker-brood, obtained queens, it may be possible to in- 

 duce bees to construct royal cells where the Apiarian pre- 

 fers to have them, by inserting a small portion of royal 

 jelly in cells containing worker-larvae ! If left to them- 

 selves, the bees often so crowd their royal cells together " 

 see PI. XV. " that it is difficult to remove one, without 

 fatally injuring the others ; as, when such a cell is cut into, 

 the destruction and removal of the larva usually follows. 

 To prevent such losses, I usually proceed as follows: 

 When I have selected a comb with unsealed brood, for 

 rearing queens, I shake or brush off the bees, and trim off, 

 if necessary, the empty cells at its margin. I then take 

 an unsealed royal cell which usually contains an excess 

 of royal jelly and remove from it a portion of the jelly,
