THE POTATO SIDE OF THE 
POTATO DISEASE. 
Іт is probably in this direction that a cure, or 
remedy, will be found. We now know perhaps all 
that is to be known of the fungus side of the ques- 
tion. Science has tracked it through the mysterious 
round of its multiform life, or lives, and has told us 
where to look for it, and how, and supplied data for 
its destruction wh 0 р ut |

threw some light on these points, and probably the 
result of experimenting directly on the anti-Perono. 
spora power of different chemical compounds might 
result in a specific antagonistic to its growth,

Again, the  Peronospora might be starved 
by a long course of rotation of cropping. How 
long can the resting-spores exist without bei

of its stages live without feeding upon or destroyi 
Potatos? An answer to these queries might enable us 
to arrange a four, five, or six-c stem 
cropping, that would drive the plague out. This
