LIME-SULPHUR MIXTURES FOR SUMMER SPRAYING. bea 
In the early part of the season the weather was very wet, so that 
the fruit became badly infected with scab, but later it turned dry 
and the brown-rot was unusually light for this variety. 
As shown in Table I, nearly 37 per cent of the crop on the unsprayed 
trees rotted, while only about 10 per cent to 12 per cent of the crop 
on the sprayed plots was affected, a difference of about 25 per cent 
in favor of the treatment. The skin of the peach is so easily bro- 
ken by insects and other agencies that it seems almost impossible 
to hold the disease down to less than 10 per cent of the crop in sec- 
tions where it is serious. 
In sorting for scab, every peach that showed a trace of tlie dis- 
ease was counted, and these were again sorted and a count made of 
the peaches that were badly affected. Those that fell into the badly 
affected class were as a rule thoroughly spotted over one side, cracked 
more or less, and unmerchantable. It will be observed from the 
table that 93 per cent of the crop on the unsprayed trees was affected 
with scab, and that 42 per cent of the crop was so badly diseased 
that it could not be marketed. On the other hand, practically none 
of the fruit on the sprayed trees was lost from scab, and only about 
16 per cent to 21 per cent of the crop was affected at all. Nearly 
all of the affected fruit on the sprayed trees had only small spots 
of seab—mostly inconspicuous specks which did not injure its mar- 
ket value. 
EXPERIMENT IN ILLINOIS. 
At the request of and in cooperation with Mr. H. A. Aldrich, an 
experiment was conducted on his place at Neoga, Ill. The work was 
done in a 20-acre orchard consisting of apples, peaches, and cherries 
about 7 years old. The peaches occupied every alternate row and 
the cherries alternated with the apples in the other rows. The 
entire orchard, with the exception of three rows, was divided into 9 
plots, and several different mixtures were tried, but only the lime- 
sulphur work will be discussed here. 
This experiment was undertaken after the plans for the season’s 
work had been made, and it had to be carried on in connection 
with work in Arkansas and Nebraska. The writer was therefore 
unable to reach the orchard for spraying the plots oftener than 
onceamonth. The principal test was made on the Elberta, although 
the Carman, the Waddell, the Picquet’s Late, and some other varieties 
were included. 
There were about 20 Elberta trees in each plot, and they were 
sprayed on May 20, June 19, and July 17. The first date was about 
a month after the petals dropped, and the last date a month before 
the crop was picked. Plot 21 was treated with self-boiled lime-
