never knew what the "yellows" was on this
farm until about 3 years ago, when we had
one tree in the outside row along the public
highway.

The yellows is now worse among my
neighbors than with me, and they have it on
land never known to be set in peach trees
before - sooner than on this farm - and in 
orchards set out within 10 years.

The first tree I ever saw with yellows in
Kent County, Del. was near Camden, about 10
years ago.  The tree was left stand until it
died.  The orchards around Wyoming, [Delaware] and
especially in the vicinity of that tree are
badly affected, some orchards being entirely
destroyed.

My father was a great patron of the peach
and seemed to understand the peach need
as early as 1840.  His theory and practice
was not to push the trees too much.

The "yellows" seems to be propagated under
these conditions: First always where they have
been mostly cultivated - as around Boston,
New York, Phiadelphia as early as 1780. Secondly
propagating from unhealthy seeds and buds.
Lastly, too much pushing of the trees by improper
manures and on rich lands with close
planting.

Of course, there are many theories and
I have mine - [ i.e.]

When the yellows has once been introduced
into a section by any or all of these
causes that the disease becomes epidemic - 
goes in the air and is breathed into the
trees by the leaves and the sap thus poisoned.

Fortunately for me, we have had as yet only
about 50 trees but of 10,000 cultivated nearly
all the time for 59 years - as one orchard
has worn out we have set about the same
amount on another part of the farm
