PEACH SCAB AND ITS CONTBOL. 51 
injury resulted from the arsenate of lead. Inasmuch as the second 
application, being the primarily important scab treatment, was quite 
heavy, this result is not surprising. The fact that no such deleterious 
results attended the use of arsenate of lead in combination with the 
self-boiled lime-sulphur indicates strongly that the addition of lime, 
as in the first application, would have prevented or minimized the 
injury. If the lime is necessary as a precautionary measure in the 
first application it would seem equally so in connection with the sul- 
phur paste in the second. 
Though, unfortunately, no plats in which lime was added to the 
arsenate of lead and sulphur paste in the second application were 
included in these experiments, the practicability of its satisfactory 
addition was shown clearly in an adjoining orchard. At the writer's 
suggestion, the addition of lime, at the rate of 2 pounds to 50 gallons, 
was made in the second application on the 30,000-tree orchard of 
the Habersham Orchard Co. In all other respects this orchard was 
treated similarly to plat 9. The foliage went through the season in 
excellent condition and the control of diseases was eminently satis- 
factory. However, the work was, of course, not experimental. 
These observations on foliage injury are presented merely as field 
notes upon what appeared to be a clear case of arsenical injury. 
They are not set forth as warranting generalizations, but merely as a 
further warning that, as would be expected, very considerable injury 
may result under certain conditions from heavy applications of 
arsenate of lead (diplumbic) with sulphur paste. It should be clearly 
borne in mind, however, that there was no evidence to indicate that 
the injury was any greater than it would have been had the arsenate 
of lead been applied alone. 
RESULTS ON FRUIT. 
Plats 1-6: Carman. 
Results were taken at harvest time in the manner previously 
described, upon representative trees of plats 1, 2, and 6. In all cases 
the count trees were selected as typical of the plats which they 
represent. As it reached the proper stage for shipping, the fruit was 
gathered in successive pickings by the. regular orchard employees, 
being thus harvested in the same manner and at as nearly as possible 
the same stage as the rest of the fruit of the commercial orchards. 
The fruit from each tree was picked separately and promptly turned 
over to the writer for examination. The records for each tree at 
each picking were thus kept separately throughout. The summarized 
results of this count work appear in Table X, while certain facts 
which can not be shown in tabular form are stated as follows :
