         Winogradsky Column (Or something like that)
 
 
 Several months ago Hemant Chikarmane of Woods Hole described 
 a fascinating sounding project for all us Mr Wizzards.
 
 I followed the instructions to the letter (more or less) and 
 got exactly what I put in plus a little algae and a few 
 emergent blades of grass.
 
 I seem to have lost his email address and want my money
  back :)    Besides it is tying up a very useful graduated 
 cylinder.
 
 Are you around Hermant?  Has anyone else had problems 
 getting this going?
