Re: Seed swaps

Peter Loewer,  Thanks for the info about kudzu.  I had known it was imported 
as an erosion control, but had assumed it was more general than you wrote.  
While railroads have been very useful their need to control costs for R.O.W. 
maintenance has left some problems.  I have been told that R.O.W, s were 
treated with arsenic salts to stop vegetation.  I am inclined to believe that 
because I read about similar use of arsenic for domestic turfgrass infested 
with broadleaf weeds in the nineteenth century.
