To show its nature in our climate more fully, it is well to 

 state that mulching the whole spaces between the plants 

 with ten inches of hard coal ashes and cinders for a period 

 of twelve years in Iowa gave continued crops of large fruit 

 without a trace of mildew, and this experiment included 

 varieties subject to mildew with common culture, such as 

 Industry and Triumph.
