Dr. Kedzie believes in the contagious nature of the disease,
but thinks that impaired vitality forms a condition exceedingly
favorable to its development.  To me the impaired vitality
is rather a result of the disease.  He says: "It is my
opinion that not only is the tree enfeebled because it has
the yellows, but it has the yellows because it was first enfeebled."
p. 177.  This conclusion is not warranted by the
facts.

[Latitude alone is no <s>fit</s> criterion of the fitness of a
locality for peach growing.] except in a very general way.

Dr. Kedzie quotes Wm. Reid, of New Jersey, who says:
"Eight of ten years is as long as we can get peach trees to
live here."  He says they invariably die off with the yellows.
p. 479.  Quoted from the Horticulturist. 1861, p. 129.

Consult writings of Mr. Fay in Prairie Farmer. He believes
yellows to be contagious.

Dr. Kedzie says: "The woody growth of peach trees must
be encouraged even at the expense of present fruitfulness."
p. 481. [In my observation the rapid growing vigorous trees are
quite as likely as any to develop the yellows.]
