Other Methods 
have been tried for preventing the issue of swarms, since I 
introduced the term “Non-Swarming System”; but all 
have come short of the desired object through incorrect 
application, and a failure to understand the needs of the 
case; requiring constant attention and more labor than 
usual; while at each operation, whether in using a double 
hive with a revolving motion, or shifting the entrance from 
one chamber to another by other means, the entire economy 
of the hive was disturbed, unless inter-communication was 
allowed as in the Double Conqueror hive. 
Swarm Attachments 
for. securing swarms, when they issue, were devised by me 
in the year 1888, and for some years similar contrivances 
have been mentioned both in English and foreign journals 
though complete satisfaction seems seldom to have been 
attained by their use. 
I still’ adhere to my non-swarming plan, or that which 
helps to restrain bees from the deszve to swarm, as being by 
far the more simple and effectual, but as there are many 
who for various reasons are unable to control swarming, I 
illustrate my earliest design in Swarm Catchers (Fig. 34), 
which requires little attention when once in position. 
It is simply the arrangement of my usual swarm pre- 
venting chamber under the brood nest, with a floor between 
having a central opening covered with excluded zinc. The 
whole front of the lower chamber is covered with excluder 
zinc, set out 13-inch, and reaching up to and covering the 
front of a porch which comes in front of the main entrance. 
The alighting board has here several inverted cones so 
inserted that the queen failing to make her way out with 
the swarm finds a passage into’ the lower chamber from 
which she cannot return, and where the bulk of the swarm,
