The bordeaux mixture was made by the usual method. To 
each barrel of freshly prepared mixture either one pint of arsenite 
of soda or three pounds of arsenate of lead were added. These 
proportions were used for the treatment of all varieties under 
experiment.

This was prepared by first shaking the lime to a thin white- 
wash. The sulphur was then added and was stirred until it was 
thoroughly distributed throughout the lime; after which the mix- 
ture was boiled from one to two hours.

The sulphur was made into a paste with six gallons of water 
and was then poured over and well mixed with the lime. Water 
was used as needed to keep the lime-sulphur material during the 
slaking process in the consistency of a rather stiff paste. As 
soon as the lime was slaked, the full amount of caustic soda was 
added and was stirred in the wash until the boiling had ceased. 
In spraying the trees one application of the sulphur wash was 
‘made before the appearance of the leaves while the bordeaux- 
arsenical mixtures were applied as follows:—(1) Before the leaf 
buds burst; (2) just after the blossoms fell; and (3) from ten to 
fourteen days _iter than the second application, according to the 
plan of treatment as previously outlined.
