This work should be done as rapidly and carefully as possible so as to prevent chilling of the larvse and hardening of the royal jelly. It has been found that the introduction of royal jelly is not essential to success, but its use is considered preferable. HOW TO START THE CELLS. The chief difficulty in rearing queens by this method is to get the cells accepted. As a rule, some will not be accepted. The rejections are not greater, however, in case of artificial than in case of natural. Fig. 2.—Standard frame with bars of queen cells on wooden bases. The upper bar holds cells of the Root pattern. (After Phillips.; cells. Once started, they are usually completed, even if transferred from one colony to another. Sometimes it is the practice to start cells in a queenless colony and after 24 hours to transfer the bar to a colony- with a queen, taking care to protect the cells from the queen by an excluder. (See fig. 3.) The bar holding the cells should be about 3 inches below the top bar of the frame so that the cells are placed in the middle of the brood chamber where the heat is most uniform. If more than one frame of bars holding cells is placed in a brood chamber, care should be taken not to have too large an open space in the chamber. It will be well to separate the cell frames by a frame of brood. Italian stock does not accept large numbers of queen cells so readily as do Cyprians or Carniolans, particularly in Porto Kico, possibly because of the high temperature. It may, therefore, be desirable to. Please note that these images are extracted from scanne
