BACTERIA ON THE FARM.

bACIEhlA UM HE hnm'
Diseases Of plants are doing more to
cause losses to farmers than is done by
insects. 1t is possible to combat in
scots, because they are easily reached
BY appropriate remedies, but bacteria is
beyond the province of the agricultur-
list, because there are so many different
kinds which work in various ways Ex-
periments have been made with peach
yellows for several years, and the CON
cusion is that it cannot be prevented by
any method Of cultivation or other treat
ment, except to remove the tree, root
and branches, and consign the whole to
the flames. Diseases Of tomatoes and
cabbage have been shown to be bacteria,
which gather at the minute openings

MANURE AND BACTERIA
The manure heap is the receptacle
into which not only the NTH OF the
farm is poured, but the refuse weeds
stalks and other useless articles are also
added. As hotbed for disease and the
propagation of bacteria the heap is un.
surpassed The warmth, moisture and
materials in state OF decomposition
afford the best conditions for producing
the causes which the farmer desires to
prevent. Understanding these facts the
question is how to avoid the d'hculty

ROTATION A REMEDY.
Plant disease may exist in the soil
for several years, but with system of
rotation some Of the difficulties may be
overcome. Potato rot may occur every
year if potatoes are grown on the same
soil every season, and disease of cabbage
may exist continually as long as the
field is devoted to that crop only, but as
the bacteria which attacks cabbage will
not affect potatoes, a change OF crops
destroys the conditions most favorable
to the bacteria. Some kinds of bacteria
exist hut short period, while other
change of crops is made there will arrive
