of water, and then to stir until an even distribution of the in-

EXPERIMENTS WITH MISCIBLE DANI? 
Following the general plan adopted by the Station in conducting 
tests of spraying mixtures for the control of the scale, separate 
blocks of apple, peach, pear and plum trees were selected for treat- 
ment. All the trees were thrifty, and, while they were not usually 
incrusted, the scales were plainly visible upon the bark. In each of 
the plats applications of miscible oils were made according to the 
printed directions, using various strengths; and, for the purpose of 
determining the comparative merits of the respective spraying mix- 
tures, the rows immediately adjacent to trees receiving the oil treat- 
ment were sprayed with the kerosene-limoid mixture and the sulphur 
washes. The miscible oils used in these tests were Scalecide, Kil-o- 
Scale and Surekill. All the trees were sprayed once and as soon 
as they were dry were treated again for the purpose of thoroughly 
covering the parts imperfectly coated by the first application. ‘These 
tests were made in seven orchards. This bulletin contains the de- 
tails of the work in three of the orchards which are fairly repre- 
sentative and which are sufficient to indicate the trend of the results 
of the experiments. The number of trees in these three orchards 
sprayed with miscible oils is 1368, divided as follows: Orchard 1, 
43 trees; Orchard II, 46 trees; and Orchard III, 1279 trees. 
eA SAND RESUS OF EX PERIMENTS, 
’ ORCHARD I. 
In this orchard 33 plums of ten years of age and Io apples of 
twenty-three years of age were sprayed with Scalecide or Kil-o- 
Scale at the rate of one part of miscible oil to either fifteen or 
twenty parts of water. The applications were made December 13, 
1905. All trees, especially the apples, were well infested with the 
scale. Blossoming .commenced May 4 and continued till May 106. 
A number of trees did not blossom. ‘This, it is thought, was not 
attributable to the treatment. With this exception the appearance 
of the trees was normal.
