156 REPORT OF THE HORTICULTURIST OF THE 
A comparison of the results secured the past season with 
potassium sulphide, with those secured on the same tree in 1885 
and 1887 with soda hyposulphite, would indicate that the former 
proved the more effectual. Such a comparison, however, may not 
be just. 
In a second trial, ten trees of the Fall Pippin apple were treated, 
as above described, with solutions of three compounds of sulphur, 
viz.: soda hyposulphite at the rate of an ounce to ten gallons, 
potassium sulphide at the rate of half an ounce to the gallon, and 
calcium sulphide in a saturated solution, the sprayings in every 
case being made on the same day and in the same manner. The 
trees were divided into three series, the first, fourth and seventh 
forming one series, the second, fifth, eighth and ninth forming the 
second, and the third, sixth and tenth the third series. The first 
spraying was given June 5, by which time the leaves were well 
expanded. Other sprayings were made June 16, June 27 and July 
2, each of which shortly succeeded a hard rain. 
On September 21 the fruits on the sprayed and unsprayed 
portions of each of the ten trees were picked, with the exception 
of a belt about three feet wide across the center of the trees where 
the sprayed and unsprayed parts were supposed to meet. The 
apples were then assorted into three qualities, as described in the 
case of the crab-apple tree, with the following results:
