jacent to il, was selected as a check
on the test.
During the years 1913, 1914 and
1915 careful record had been kept
of these trees as to the amount of
rosette. consequently the tables
given later on will show the condi-
ton of the trees before and after the
treatment; also the condition of the
trees in the check block during the
same years.
Observations were made on the
condition of the trees in the treated
block in the fall of 1915 by Guy W.
Firor. of Louisville, Ga, and S. NJ.
McMrrran, a specialist on pecan
rose!xa of the United States depart
ment of agriculture. They have
stated that in the fall of 1918 there
was not a rosetted tree in the treated
block. The reader should pay par
ticular attention to these statements
and refer them to the tables given
further along.
The following tables give the con-
dition of the trees in the treated
block by tree and row. Rows 3 and
10 were treated with the pine straw
mulch. while rows II and y were
used for check. Attention is called
to the letters ''h," meaning tree
without rosette; "a, meaning rOset-
ted, but without dead twigs, and
3D." meaning rosetted with dead
twigs.
All the trees in these blocks are of
the Stuart variety. The year 1919
was their fourteenth year as orchard
trees. The orchard in which these
blocks are located had been farmed
in cotton and corn until 1872. Since
1912 there has been one crop of cot
ton in the orchard; the rest of the
crops have been Of field peas for
turning under.
The records made in 1913, the first
year in which the trees given in the
above table were observed, were
made with less refinement than dur
ing subsequent years. A tree that
was Enthusiastically rosetted was
marked rosetted Cb), otherwise, it
was marked without rosette CID. In
1914, following the observation oil
1918, three classes of trees were
made, viz: healthy CHI, rosetted with
out dead twigs (a, and rosetted With
dead twigs CD.
1t will be noticed that there was
an increase in the number or trees
rosetted from 1914 to 1915.
In 1915 the trees in rows and 10
had not received any treatment for
rosette; in 1919 these same trees had
bee nmulched for two years with
pine straw as described. Conse-
quently, comparison of the condi-
ton of the trees in 1915 before
mulching) and 1919 latter having
been mulched for two years with

Going over the figures of this
table shows that in a block of 43
pecan trees there were, in 1918, 8
trees free from rosette, 10 trees
rosetted, but having no dead tWlgs
showing, and 20 trees rOsetted with
dead twigs. The trees were mulched
in 1867, and in 1919 there were 40
trees free from rosette, 3 rosetted
without dead twigs and none roset-
ted showing dead tWigs-a health
Improvement of 400 per cent. The
attention of the reader is called to
the statement made earlier in this
publication whereby the observations
made by Guy w. Firor, Louisville,
Ga, and S. NJ. McMurran, of the
United States department of agrlcul-
ture, Indicate Enthusiastically that the
trees had recovered from the rosette
by the summer of 1918.
To avoid the possibility Of making
a wrong conclusion from this test a
block If trees was used as a check
IN the tested block. This block con-
sisted of trees in rows II and II in
