the sulphur wash April 7th, continued until April 12th; work de- 

 layed every day by rain. Bordeaux arsenical mixture was applied 

 May 18th to 20th, June 2d to 6th, and July 6th to 8th, rainy weather 

 during most of the spraying time. With the picking of the fruit, 

 September 27th, the apples were carefully examined with respect to 

 scale, codling moth and scab. 



The outline of their experiments were as follows: Section No. 1, 

 sprayed once with sulphur wash; Section No. 2, sprayed once before 

 buds opened with sulphur wash, and twice after drop of petals with 

 Bordeaux and arsenical poison. 



Section No. 3, no treatment. 



Section No. 4, sprayed three times with Bordeaux and arsenical; 

 once before and twice after blossoms dropped. 



Average of wormy fruit on Section No. 1, 27.6; average of wormy 

 fruit on Section No. 2, 3.6; average of wormy fruit on Section No. 3, 

 24.3; average of wormy fruit on Section No. 4, 8.9; sound fruit from 

 trees treated with Bordeaux arsenical mixture averaged 93.8 as 

 compared with 74.1 per cent, sound fruit from checks and where 

 treated with sulphur wash alone. The application of sulphur wash 

 greatly reduced the number of scales and gave fruit practically 

 free. The average of infested fruit from sulphur treated trees was 

 5.3, as compared with 17 per cent, of scaly fruit from untreated trees. 



In every instance where the work has been properly done the 

 results have been very satisfactory for scale insects, codling moth 

 and scab. 



The Connecticut Experiment Station has likewise been experi- 

 menting for several years with different sprays. With the L. S. S., 

 boiled and self-boiled, both have given good results, but on the aver- 

 age, best results have been obtained from the boiled preparation. 

 At the Paragon Fruit Farm we have been spraying for several years, 

 mostly for scale, having tried various sprays with remarkable suc- 

 cess. Our preference is for the lime, sulphur and salt, boiled. With 

 this we have been able to hold the pest in subjection; so much so that 

 we no longer fear it. We have had trees so badly infested as to 

 be considered hopeless. We not only saved these trees but com- 

 pletely eradicated the scale without the loss of a single crop of 

 fruit and regained the thrift of the trees. Last fall we purchased 

 a new spraying outfit and wishing to test it, we boiled 100 gallons 

 of L. S. S. and sprayed a portion of the orchard that was infested. 

 The day was very cold and windy, so we could spray only one side 

 of the trees. This was done on November 25th. Upon examination 

 this spring we found no living lice beneath the scale on the side 

 sprayed, but on the opposite side and upon the under side of limbs 

 where the spray did not come in contact with the scale, we found 

 plenty of live lice, thus showing that when the work is rightly done
