 therefore elaborate brushes for keeping these valu- 

 able organs clean and neat and in working order. 

 They always remind me of the brushes I use myself

 removing very small impurities. 

 With this the wasp cleans her 

 precious feelers much as you

 wings when they have fallen 

 in a jam-pot ; only the wasp's 

 mechanism is much more beau-
