2. Two treatments with Bordeaux mixture, one being made 
‘immediately before and the other immediately after blossoming, 
diminish the scab to some extent butare not sufficient to control it. 
3. On account of the injury to the fruit of certain varieties it 
was doubtful whether it paid to treat them the second time after 
blossoming. 
4, If not thoroughly done the treatment will be unsatisfactory. 
In one instance where two men were spraying side by side the 
difference in the work could be seen for many days or even for 
weeks afterward. One did the work well, the other did not. 
Where the work was not well done the scab fungus was more 
abundant and did correspondingly greater injury. This did not 
occur in the experimental plot. 
The season of 1894 was so unfavorable for securing the best 
results from spraying for the prevention of pear scab that any 
treatment which succeeded in controlling the disease in such a 
season may reasonably be expected to succeed in more favorable 
seasons. It is safe to conclude concerning pears like the Seckel, 
which are subject to the scab, that for all practical purposes the 
best results may be secured by three thorough treatments with 
Bordeaux mixture,” of the 1 to 11 formula,” given as follows: 
First Treatment. After fruit buds break, but before blos- 
soming. See figures 1 and 2, Plate II. 
Second Treatment. Immediately after blossoming. See 
figure 3, Plate ILI. 
Third Treatment. From 10 to.14 days after the second 
treatment. See figure 4, Plate III. 
To prevent injury from codlin moth Paris green or London 
purple at the rate of one ounce to 11 gallons of the mixture 
may be used with the second and third treatments. If the trees 
are infested with the eye-spotted bud moth use the arsenical 
poison with the first treatment also. Generally speaking, it is best 
to use either Paris green or the London purple with all three 
treatments. 
Treating APPLE ORCHARDS FOR SCAB.* 
Since this report will reach many orchardists who are interested 
equally as much or more in the treatment of apples as they are 
in the treatment of pears it is well to state that the treatment
