114 APPENDIX. 



stance has rendered the majority of the so-called " Moth- 

 traps'' nearly worthless. 



The fact, however, that the moth-miller is most active in 

 the night-season, when the bees are always quiet in the hive, 

 has led to the practice of placing lamps or candles within the 

 bee-houses, at a short distance from the hives. This plan, 

 though partially effective, was liable to many objections, and 

 finally abandoned sfltogether. For instance, the flame of a 

 single lamp or candle was so slight and powerless, that it often 

 only partially crippled the insect, by singeing off the ends of 

 its wings, leaving it to creep into the hive, deposit its eggs, and 

 thus perform all the mischief of which it was at any time 

 capable. A second objection to this method consists in the 

 smallness of the wick, and the constant liability to sudden 

 extinguishment by gusts of wind, or the propensity of the mil- 

 ler to plunge into the blaze. There has been no method dis- 

 covered, whereby the flame -may be protected from the wind, 

 as the use of a screen, whether of gauze, glass, or any other 

 substance which could break the force of the wind, would 

 obviously defeat the very purpose sought. These objections, 

 together with others of less moment, have gradually brought 

 this method into disuse. 



We have, however, succeeded in completing an invention 

 which is liable to none of these drawbacks. Its advantages 

 are, briefly : First, the flame is protected from the fiercest 

 blasts of wind, and is so arranged that no miller can by any 

 means reach the wick; neither of these circumstances in the 

 slightest degree injjiairing the efficiency of the instrument. 



Second, the flame is large, powerful, and more intense than 

 can be produced by any ordinary method ; it is also thrown 

 into a horizontal direction, so that a vessel of liquid may be 

 placed beneath, to receive the dead millers and those which 

 may have been only partially disabled. We are able, also,
