can see in the mass with the naked eye, as I will explain later.
The same appearances as to bacteria cannot be obtained with
the peach yellows.  Careful examination of trees affected by this
disease reveals no bacteria in quantity; I do not say that bacteria
may not cause the disease, but there is no such abundance of
them as in pear blight.  If they occur in yellows it will require
special manipulation to demonstrate them as it does in consumption;
they certainly are not abundant and easily found." Ibic. p. 199.

"Duration of bearing [of peach trees in Hunterdon Co., N. J.]
from 5 to 7 years from commencement [at 3 to 4 yrs. from planting].
This will vary from several causes, such as variety of soil, exposure
etc., some orchards bearing for 10 yrs., some not giving
more than 3 or 4 good crops."--Thos. C. Haywood, of Flemington,
N. J. in Rep. N.J. St. Bd. of Ag. 1877 p., 129.

P. M. Augur (Pomologist) of Middlefield Conn. in 20th Annual Rep. Conn. Board of Agric., 1886,
says (p. 345):- "Dr. Hape, of Georgia, has assured me that the yellows
did not exist south of the Potomac river, and yet I think I
found genuine symptons of the disease in Tennessee. x x Of all localitites
on our globe for successful peach culture probably none excell the region
between the Chesapeake and Del. Bays. x x Delaware orchards
certainly exceed ours in longevity and productiveness." [No longer
true for New Castle and Kent Cos.]
