These papers and notes are:

1. "On Peach Trees. By Joseph Cooper, of New Jersey
Read Jan. 14, 1806." pp. 11-14.

Mr. Cooper knows the borer well, and speaks of it as
abundant. But he apprehends that sudden transistions from
heat to cold and from cold to heat "are more destructive to
peach and cherry trees than insects, as I have had hundreds
of fine trees perish in one summer, after an irregular winter
without being in the least injured by worms:  [Was this yellows?]
Farther south where the climate is more even and the
spring two weeks later he has from good authority that peach
trees live "to the age of thirty or forty years."  All this
he attibutes [attributes] <s>to backwars</s> to the backward springs and general
effect of milder Ocean climate.

He examines his peach trees every spring and pulls out
those "in a declining state."  Says the body or trunk appear
to be the seat of the disease. [Nothing clear as to "yellows"
here.]

2. "On Peach Trees, By Richards Peters, Read Feb. 11,
1806." pp 15-24.

In this paper so far as I can find occurs the earliest
use of the word "yellows" as applied to a disease of the peach.
