6 BULEETIN OF THE BUSSEY INSTITUTION. 
‘© Ags another item of experience I may mention the fact that 
nearly twenty years ago three trees grown from northern seed 
were budded with the Early Crawford peach. The buds all lived, 
and when two years old from the bud the trees were transplanted 
to the northern slope of a hill, the soil of which was a light sandy 
loam. ‘The trees grew, and for five years produced a good crop 
of excellent peaches, though after that time the ‘ yellows’ appeared 
on each tree. To observe the progress of the disease no limbs 
were cut off, but all were left to decay on the trees. ‘The second 
year after the ‘ yellows’ appeared I observed that a sprout had 
commenced to grow near the roots of each tree, and below where 
buds of the Early Crawford had been set. ‘The sprouts made a 
very good growth considering the nature of the soil, and the fact 
that no fertilizer had been applied. The second year the limbs 
from the sprouts were up near the centre of the trees, and were 
surrounded by branches of the Early Crawford, dying with the 
‘yellows’; not a limb of the Crawford was cut off, but left to 
decay and fall to the ground, which they did in a few years, leaving 
the trees coming from the sprouts of the natural trees master of 
the situation. One of these trees, which I have left standing that 
I might continue the experiment, is now a good shaped tree; it 
produced a full crop of peaches last year, notwithstanding the 
peach crop, in Hingham, was a failure. 
‘¢ From the above facts I am led to draw the inference that at 
least one variety of peach trees is not subject to the ‘ yellows.’ 
Moreover, a careful review of my experience with seedling peach 
trees, many generations of which have been grown in one locality, 
leads to the conclusion that they become strong enough to prevent 
their wood from being contaminated by the ‘ yellows’ from trees 
suffering from this disease only a few feet distant from them, 
though they may not in all cases become strong enough to prevent 
the pollen from trees having the ‘ yellows’ affecting the seed 
coming from such crossing. 
‘* As the peach tree is a native of a warmer climate than ours, 
only the most hardy varieties would be likely to succeed here. 
This view of the matter has not been taken by our peach growers — 
who are accustomed to plant pits or trees that have been brought 
from Southern States. The change of climate creates a weakness 
which invites the ‘ yellows’ and other troubles.”
