Clo%igli's Revolving Light-House Fly Trap. 



J. S. Cloiigh, 231 Pearl street. 



The clockwork is in the base, from which 

 rises the central column, which is covered 

 with sand, and on which the bait (molasses 

 and sugar) is to be spread with a sponge. 

 A rotating spindle passes through the center 

 of this, and carries a platform on the top, 

 from one side of which the catcher projects 

 downwards, close to, but not in contact 

 with the sanded cone. On the top of this 

 platform a cage, containing water in its 

 base, is placed, into which the flies are at- 

 tracted by the light, when started from 

 their enjoj'ment of the sweets of life by the 

 catcher. When the spring is wound up 

 and the trap baited, the catcher and cage 

 commence revolving around the sanded 

 cone, and the flies are caught, made prison- 

 ers, and finally find a watery grave.
