"YELLOWS IN THE PEACH OR FACTS VERSUS FUNGUS." By J. W.
Kerr, Denton, Md., Feb. 12, 1879.  Mr. Kerr states his belief
that fungus has nothing to do with yellows, but that it [the fungus] is
due to <s>the</s> Aphides. He says: "On an examination of trees
from two to five years old, which had been killed by the Aphis,
I found the roots to be visibly marked and netted over by a mildew
or fungus; again, trees upon which the inset were preying
upon in countless hundreds, and which were so reduced in
vitality, by the ravages of the insect named, as to barely
afford sustenance for them, these trees when dug out were
found to have the mildew marking their roots,  though less
plainly visible."  He also found the mildew on roots, injured
by frost before planting two years previous.  He thinks the 
fungus follows the weakened vitality. Ibid. 1879., p. 102.
[Mr. Kerr had seen yellows in Pa. but in a letter to me in
1888 says it has never appeared in Caroline Co., Md.]

The peach crop of Maryland in 1879, on page 358, October

1,490,000 boxes.  The market was overstocked and thousandss

during the season has not been fifty cents."
