dion when it breaks from the attacks OF disease will be
competent in proportion he the nteacton of
the parts and forces that constitute healthy cane plant
and physiology OF the cane plant
This fairly plain but bv no means states the whole
case for It is fact that only physiology of plants
very mPereety understood yet but in particular that of
stands behind shat some other plants notably those
OF the temperate regions where the cultivation has
hitherto been most active.
From this you will that study of the healthy cane
Pant must constitute no OF the work OF any
st1tuon that attempts deal nationally diseases of
No matter what may to be efficient it must
be an institution for the study of both physiology path
OOgy.
OF subject that we have met to consider is not
one that be mastered in afternoon most that
be done is up few principal topics deal with
them briefly and way sketch as completely as may
be an outline OF the existing condition of plans
which may be adopted for their improvement
Cane being plant which long object of culture has
been brought to such state that is liable diseases
which would be little subject in its wild Moreover
it plant which grows only tropical subopcal
g1ons where the various enemies of flourish
numbers Hence find the crop to consider is
subject diseases of Fungi of every class attack it
Some OF its diseases caused by microbes the lower of
the ungod scale and others
toadstoos the other and higher
Furthermore part of the plant attacked
OF the root diseases OF the se diseases of the leaf and
special diseases OF the blossom is of course impossible today
to carefully into the of the plant euay
Pose 10 scy INTO the anatomy OF all the
which attack the plant such disease Time
would permit. 1t would be impossible any planta-
ton busy he with other matters give that
attention to these subjects which would make him competent
pathoogist but glad say that without complete knowl
cage either OF the anatomy OF the cane plant or OF the facts OF
pathology it possible knowledge
our subject as viii be extremely useful and profitable
engaged III growing cane In order however, to reach this state
considerable of close study necessary by
close reasoning the resulting observations
this part of the subject without calling attention aids
this end namely the ordinary pocket lens and the microscope
With regard the first have hesitation whatever saying
that every manager and skilled employee should carry
his pocket good handen enable him make such oberva
useful understanding of the subject 1t is with hesitation
that recommend much general of the microscope
My ideas on this subject differ radically from those of
of contemporaries that rather ddnt about presenting
them will only briefly that convinced that the micro

Any healthy organism less subject variety of

In these cases we have hesitation in saying that disease
On the other hand have factors of different kind
which, though equally fatal such different that
We never think OF abtng their NERVOUSNESS to disease
Large numbers of the people of India annually killed by tigers
but the Taught of tigers does not constitute disease IT, how
ever the size OF the attacking organism be reduced you VIII see
that approach the limits of disease ordinarily that
ones are sometimes attacked by lice Now ousness might by
slight stretch be included within the meaning of the word dis

disease. The itch is welknown disease 1t is caused by

clearly the limits of what call disease in order to show that
