New Castle, Delaware.
March 31, 1888.

Erwin F. Smith.

Dear Sir:- In reply to yours of
March 17 last - I would say , after consultation
with E. R. Cochran, we put the number
of [peach] trees in New Castle Co. in 1870 at one
million trees of all ages.  Now, or in
1887 about 600,000 trees. In 1875 - 
there were probably 1,750,000 [peach] trees
in New Castle, County, Del.

Very truly yours,
Jno. J. Black.

South Haven, Mich. March 26, 1888.

Erwin F. Smith

Dear Sir: - I am in receipt of your favor of
24th instant.  I have little personal experience bearing
upon the question of soil starvation as a cause of yellows,
and I have never planted a tree in place of
one diseased; but this has been done to a
considerable extent in orchards here, and I
have not heard of disease tracable [traceable] to this cause.
I will try to supply you with evidence such
as you desire, and will see that the cases
are well-defined and authenticated.

Very truly yours,
T. T. Lyon,
