of the plants affected are the tips of the roots. The 

 water has laid at the roots for perhaps a very short 

 time, but these roots are most tender, and when over- 

 charged with water rot at once, as one can easily prove by 

 digging up one of these plants the next day after the rain. 

 This may be called, for want of a better term, " vegetable 

 dropsy." Fungi are not the cause, but a fungus may be 

 found afterwards making use of the decomposing vege- 

 table matter. Pelargoniums and other soft-wooded plants 

 often meet the same fate during the summer months.
