he has kindly sent to me, together with permission to make the matter 

 public, I have written the following 



DESCRIPTION OF THE DEVICE AND SYSTEM. 



At the beginning of the honey season the non-swarming device, D, 

 shown in Fig. 31, is placed at the entrances of two contiguous hives 

 each of which contains a queen and full colony of bees. The continu- 

 ous passageways, e and c', on the underside of the device, correspond to 

 the entrances of the hives A and B, respectively. The bees will then 

 pass, quite undisturbed, out of and into their respective hives through 

 these passageways. By inserting the slide, s?, in the end of the non- 

 swarmer until it occupies the position indicated by the dotted hori- 

 zontal lines the passageway leading to hive A will be closed at its 

 juncture with the hive-entrance, preventing any bees from entering"^ 

 said hive. The wire-cloth cone exit, ex, still permits flight-bees to come 

 out of hive A, as a hole, /«, Fig. 33, through the non-swarmer connects

 to similar openings in the fronts of hives. 



the cone exit with a corresponding hole, A, Fig. 32, in the front of the 

 hive. The super cases S of hive A are then placed on those of hive B. 



The flight bees of hive A tlnding their hive-entrance closed on their 

 return are, upon alighting at the entrance e, Fig, 31, attracted along 

 the gallery shown at </, in the cross section, Fig. 34, by the buzzing of 

 the bees at the entrance e' of hive B, and 

 enter said hive. This withdrawal of the 

 field-bees from hive A leaves this hive 

 so depopulated and so disconcerts the 

 nurse bees left therein that they will not 

 swarm ; meanwhile work is going on with- 

 out interruption in the supers on hive B 

 by the field force of both hives. 



At the expiration of eight to ten days, 

 thus before the bees of hive B have made 

 preparations to swarm, the supers, S 

 and S', Fig. 31, on this hive are all trans- 

 ferred to hive A, the slide, sZ, is withdrawn from entrance e, thus open- 

 ing this hive, and is inserted in the opposite end of the non- swarm- 

 ing device so as to close the entrance, e' ^ to hive B. The bees thus 

 excluded from hive B will be called along the gallery, g, Fig. 34, 

 of the non-swarmer by the bees at the entrance, e, and with these
