"Insects Injurious to Fruits". By Wm Saunders,
F.R.S.C. Philadelphia, J.B. Lippincott & Co., 1883.
This is a good book to buy. From it I quote:

"No. 103 - The Peach-tree Aphis,

Mygus persicat Aphis.

This aphis begins to work upon the young leaves
of the peach tree almost as soon as they burst from
the bud, and continues through the greater part
of the season, unless swept off, as sometimes
happens with surprising rapidity, by insect enemies.
These lice live together in crowds under
the leaves, and suck their juices, causing them
to become thickened and curled, forming hollows
with corresponding reddish swellings above; frequently
the curled leaves fall prematurely to the
ground [? Here he probably confounds with curl
due to Laphrina ]. The perfect winged females
are about one-eighth of an inch long, black with
the under side of the abdomen dull green, the
wingless females rusty red, with the antennae, legs
and honey-tubes greenish. The winged males
are bright yellow streaked with brown, with
black honey-tubes." ' - p. 199.  Nothing is said
about the occurrence of this insect upon
the roots.

" A Practical Treatise on the Management of Fruit
Trees etc." By George <s>Jacques</s> Jaques, N.Y. 1856.
From this book I quote as follows:-

"The yellows. This destructive disease has proved
fatal to whole orchards, in some sections of the
country.  Its symptoms are, -  1st. a growth of slender,
sickly, wiry shoots, with small yellowish leaves; 2nd, the
premature ripening of the fruit two or three weeks earlier
than its proper season. This disorder seems
most diposed to attack rapid growing varieties."
p. 212.
