a light soil was adhered to, and generation after generation of 
seedlings, each more enfeebled than the former, at last pro- 
duced a completely sickly and feeble stock of peach trees in those 
districts. 
“The great abundance of this fruit caused it to find its way, 
more or less into all the markets on the sea-coast. The stones of 
the enfeebled southern trees were thus carried north, and, being 
esteemed by many better than those of home growth, were every- 
where more or less planted. They brought with them the enfee- 
bled and tainted constitution derived from the parent stock. 
They reproduced almost always the same disease in the new soil 
and thus, little by little, the yellows spread from its original 
neighborhood, below Philadelphia, to the whole northern and 
eastern sections of the Union. At this moment it is slowly but 
gradually moving west, though the rich and deep soils of the 
western alluvial bottoms will, perhaps, for a considerable time, 
even without care, overpower the original taint of the trees and 
stones received from the east.” 
As to the appearance of the yellows in New Jersey, I will 
quote again:! 
“A gentleman to the peach ‘manor born,’ —in Monmouth 
county, N. J.—but who has resided in this vicinity during the 
past ten years, informs us that he has witnessed the destruction 
of the peach orchards in these localities during the past thirty 
llows made 
he peach 
orchards about 1856. Monmouth county and vicinity were 
markets 
with peaches. Driven from the Atlantic coast counties by fur 
yellows, the prominent peach growers of New Jersey lore 
Morris and other counties in the north of the State, W 
peaches were grown successfully until about 1867, when h 
Jersey peach growers were again driven by the yellows to fres 
fields,’ favorable localities in Delaware and Maryland bems 
chosen, from whence the eastern markets have received their, 
principal supplies during the past few years. Incipient signs 3 
yellows have appeared in Delaware and Maryland, and it 1s evr 
dent that a ‘change of base’ will soon become necessary- 
In the same volume it says: “The first record of the peach 
yellows is found in the Genesee Farmer, and was published en 
forty-five years ago. The disease as it now exists was accurately 
described. The Farmers’ Book, which was compiled and printed 
at Chambersburgh, Penn,, Sept. 16, 1845, contains a commune? 
tion from Sidney Weller, Halifax county, North Carolina. So
