Ibid. p. 128, Littleton Physick, Ararat Farm, Cecil Co.,
Md., July 6, 1841, recommends salt petre very highly for peach
trees.  His experiments began in 1836.

In The Cultivator, Albany, N.Y., 1843, p.182, C. Butler,
of Plymouth, Ct., Sept. 1, 1843, says he has had experience
with yellows.  Thinks it is contagious, but has made no experiments
beyond the common one of observing "that when one
tree was infected, other trees standing near would be, unless
the infected tree was immediately removed in which case the 
healthy trees woiuld generally be preserved." He says: "I
came into this country to reside early in 1801, and have resided
here ever since.  When I first came here peaches were
plenty.  They were not raised for market, but for the family
to eat, preserve, and give to the neighbors and friends, and
were almost as sure a crop as potatoes.  This continued to
be the case until 1810.  In December, 1809, there was a very
extensive and severe cold freezing turn, which killed nearly
all the peaches in this vicinity, and as far west as to Lake
Erie.  Since then, for some cause unknown to me, it has been
much mor difficult to grow peaches in this part of the country;
but no more difficult on plowed land than on sward.
