source that is detrimental to the growth of the peach.  Others
believes the disease of the tree originates in bad cultivation,
this idea I think has its origin in cases where the parties 
have not made a distiction [distinction] between premature and yellow trees.
I am very confident that neglect, careless cultivation, over
deep plowing, too free use of the pruning knife at the root
in search of worm, wounding the bark of the root or body of
the tree, is a fruitful means of producing the worm, and that
in turn a sure cause of decay.  Wm. Reybold says that the
borer worm is never found in the roots of trees that have the
yellows, while many other persons are equally confident the
borer worm is always present in the roots of trees having the
yellows.

Unless I have been mistaken in my observation I have
found the worms plentiful in some trees suffering with yellows
and been unable to find any worms in other trees of the
same kind. [He is right!]  In conversation  with the old peach growers of
this section I find few, if any made any searching or intelligent
investigation into the cause of the disease until the
most of the trees had died.  I believe microscopical and
chemical investigation would throw much light upon the subject.
