by this pest. The effects of the wash upon the hibernating larvee 
were not determined. 
Owing to the absence of apple scab in the experimental 
orchards no opportunity was given to determine the value of 
the sulphur wash for this disease. As it is desirable to obtain 
more data of the value of this treatment for this disease the 
experiment is to be continued until conclusive results are ob- 
tained. For the same reason as for the scab the results of the 
sulphur wash upon other plant diseases were inconclusive. Aside 
from peach leaf curl, the value of surphur sprays for orchard 
plant diseases remains undetermined and requires further in- 
vestigation. 
To what extent it is advisable to use a sulphur spray in place 
of the bordeaux-arsenical mixtures remains undetermined. Be- 
fore any satisfactory conclusion can be drawn upon the desira- 
bility of a change of sprays in the first spring treatment of the 
apple, cherry, pear and plum, data are needed upon the value of 
the sulphur wash for apple scab, fruit rot and pear scab. 
In case of the peach one application of the sulphur wash dur- 
ing dormant season may be used in place of the usual treat- 
ment with bordeaux mixture for the control of scale and leaf 
curl.

Place the lime in a kettle, or in a vat if steam is used, and 
slake it with hot water so that it forms an even white paste. 
Now add enough water to reduce the lime paste to a thin white- 
wash. The sulphur and salt are then added and should be 
thoroughly stirred in. If the mixture is not already boiling, bring 
it to this point and allow it to boil for one hour. If the wash is 
prepared in an iron kettle it will be necessary to add a bucket of 
water now and then to replace that lost in the boiling process, and
