Some three months since I asked through the pages of the Monthly if there was a remedy for the fungus known as Verbena rust. No one having offered a remedy I now give one. Pulverized charcoal applied to spots of rust removes them in a short time. I have tested its merits on some pretty hard cases and always with success.
Mr. Meehan, I have forwarded you the above remedy, thinking it would be of service to the readers of the Monthly.
