Rust in Cotton.

iect has generally been treated by two
classes of writers from very different
standpoints.
/. The scientist, the college profess
sor, who understands great deal
about science, ana who may BE- correct
as far as his experience goes, but who
has had few opportunities Of obocrva-
tion in the field.
. The practical farmer who has no.
ticed all the phenomena Of rust. but
who is unable to form conclusions
from these observations.
For years | have been observing rust
in cotton, and the conclusion which
have reached, is that it i, general
term for variety Of diseases, aoIne-
times local in the leaf but generally in
the plant itself, indirectly affecting h"
leaf. and is due to a variety Of causes.
Injury to the leaf from parasites, de-
fectiye circulation from general or
special poverty, bad and irregular sea-
sons, detective drainage. and some
times from some poisonous element IN
the soil. | have seen rust or decay
from all OF these causes, and lie who

due to any one cause j., in my opinion,
very much in error. We have il upon
