SPRAYING NOTES FOR 1904-1905. OI 
A similar although somewhat smaller plot of the same variety 
of cucumbers was again planted July 3, 1905. Spray was 
applied to one-half on July 29, August 14, 22, 30, September 5. 
The yield of the plots was as follows:—

Mildew began to develop on the unsprayed plants previous 
to the first picking, August 23. On August 30 the unsprayed 
plants were badly blighted, and by September 5 the leaves were 
dead. At this time the sprayed plants showed some mildew, 
but were not seriously injured until September 21, when the 
blight again attacked them and stopped the development of 
fruits.

* DISCUSSION OF RESULTS. 
Three years’ work with Bordeaux on cucurbits has shown a 
decided increase in yield for the first and third years, when 
downy’ mildew was present, and a decided decrease in yield for 
the second year, when no fungi troubled the plants. 
Melons treated the same way for the three seasons gave very 
similar results, with the exception that, in addition to mildew, 
anthracnose worked on the unsprayed melons in 1905. 
The old question comes up again, ‘‘ Will it pay to spray 
melons and cucumbers?’’ If we could know beforehand 
whether mildew would be present or not, we could easily 
answer this question; or if Bordeaux could be used on them 
without possible danger of injury, as it can on tomatoes and 
potatoes, it would pay to use it as an insurance. After mildew 
has made its appearance in the field it is generally too late to ° 
control it by spraying, though we have some evidence that
