(4) Apricots, almonds, nectarines, peaches, and Japanese 
plums are, in the eastern American States, susceptible to attacks, 
while European and American plums are not. 
(5) That at least one variety of peach which has been grown 
for over a hundred and fifty years in one locality here in Massa- 
chusetts and has become perfectly acclimated has never been 
affected, although surrounded by other varieties which were dying 
with the ‘‘ yellows.” From time to time there have been reports 
of varieties of peaches which have been resistant to the yellows. 
Careful investigation has usually shown, however, that sooner 
or later the so-called resistant variety has succumbed to the 
‘¢ yellows,” or the variety has never been exposed to a case of 
genuine ‘** yellows.” What was supposed to be the ‘‘ yellows” 
has usually proved to be a diseased condition due to nematodes, 
borers, or some other trouble. So commonly have these so-called 
resistant varieties failed that it has become customary to pay 
little attention to claims of this sort, or even to hold them in con- 
tempt. A Michigan peach grower expresses in the following 
words not only his own opinion in the matter, but that of the 
community at large: ‘‘ People who claim that certain varieties 
are immune or less subject to ‘ yellows’ than others belong to the 
same class that plant potatoes ‘in the moon,’ and believe pear 
blight to be occasioned by a spell of weather.” 
Here follows an account of the experience, in respect to 
peach “yellows,” of my colleague, Mr. Edmund Hersey, and 
that of his ancestors, given in his own words: — 
‘* Between 150 and 160 years ago a mariner, who sailed in a 
ship that transported fruit from Southern Europe to this country, 
gave Mr. Isaiah Hersey of Hingham, Mass., a few peach stones, 
which he planted in his garden. From these seeds he obtained 
three varieties of peaches. One was of good size, yellow flesh, 
free stone, and most excellent flavor, and was named the Hersey 
Rareripe. Another variety was of medium size, white flesh, free 
stone, and good flavor. This was named the White Magdalene. 
The third variety, which was named Mallacatoon, was a late 
peach of good size, white flesh, free stone, and of little value 
except for cooking. 
‘Seedling trees from the Hersey Rareripe would not always 
produce fruit exactly like that of the parent tree, although the
