All the preventive effect evident in my
experiments seems 10 NE certain to have
come from the earlier tres!meuts, espe
c,allY with the Bordespx mixture, and
where it reached every part OF the sur
face Of fruit. Ihis Was well shown

27, allowed to ripeD, aud we're then huug
ma showcase, where frequently haDg
fruits as samples, Rld where ripe grapes
usually rot ia week or ten days IN July
and August, Brighton especially, yet
these Brighton clusters hung there about
FIVE weeks snd were yet ell sound So
concluded that If the Bordeaux mixture
be sprayed thoroughly over the vines in
spring before they IesVe out, and over
the posts everywhere, also spray over
tee ground then again of "eaker strength
just before or as the vines bloom, and
again when the fruit is not over one
third grown, during cloudy weather er
when dew is on, that benefit will most
likely be the result. But 1t is Curl
GUS fact that Goethe never showed nny
signs Of rot during the first attack, ard
vet everywhere, almost, showed rot
during the second period, even where
well sprayed each time SID no matter
what preparation, Indicating varying
effects on different varieties.
Low, rich, and uudrained or poorly
drained land exer.S grs at influence "a
vo.ing rot, while high, well drained
grsvelly or red clay LANDS sIe UufsVorsbie
to rot, So shown in msGg vineyards in
tais region.
The most potent resistant to the
black rot appears to reside /" GER
tain varieties aud species having very
firm, dense skins, whether thick or thin,
and also probably in some acid or acrid
element residing in tie skin before
ripenipg; and hence 10 plant more
largely of such varieties as PEI klns, Ives,
Delaware, Norton, etc, known to resist,
aud TO bring up new varieties from these,
sud the II 3tiVa!is, Ripsris, Rupestris, and
other sp cies nesrly slwsys found re-
sistive, promise the most certain escape
from this destructive mslady.
