each application is less than one cent per tree. Two men should spray 

 from 100 to 125 trees per day and do the work well. Counting the cost 

 of applying at 2 cents per tree, this makes the total cost of each applica- 

 tion of the combined insecticides and fungicides 7 cents per tree, or about 

 25 cents for four applications, this number being perhaps sufficient in even 

 very wet seasons. 



Most of the petals fell from the trees June 6 and 7. The first applica- 

 tion was made June 13, the weather in the meantime being warm and 

 damp. This application was without doubt delayed too long, for at the 

 time of the second application, June 22, diseased spots could be found 

 both upon the young fruits and upon the leaves in some of the places 

 which were thickly covered with the Bordeaux mixture, thus showing that 

 the work of the fungus began very early in the season. The first applica- 

 tion should be made, at the latest, immediately after the blossoms fall, and 

 it is probable that good results will follow one made earlier. 



The orchard was sprayed a third time July 1, and again July 22. the 

 mixture in each case being prepared as for the first application. 



The apples were harvested early in October and at that time they were 

 carefully examined with regard to the amount of scab and number of 

 worms present. The yield from two to four trees of each lot sprayed was 

 counted and graded. In most cases all the apples borne by the tree were 

 examined, but occasionally only a portion sufficiently large to give a fair 

 estimate of the character of the yield. The apples were divided into four 

 grades as follows: 1st, those entirely free from scab; 2d, ranking as first- 

 elass, or those whose market value has not been affected by insects or 

 fungi, although attacked; 3d, ranking as second-class, or evaporating 

 apples, those whose market value had been more or less reduced by insect 

 or fungous injuries, the apples as a rule being smaller than the above, but 

 not seriously misshapen; 4th, cider apples, or all those remaining after the 

 preceding grades had been removed. The apples of each grade were 

 counted, as was also the number of wormy ones borne by each tree. The 

 following table shows the result. The numbers represent the average of 

 the results obtained from the different trees:

It will readily be seen from the large proportion of poor fruit shown by 

 the table that the season was one which would put to a severe test any 

 application that might be made. Nearly nine tenths of the King and 

 three fourths of the Baldwin apples on the unsprayed trees had but little 

 market value, and from twenty-five to thirty-eight per cent, of them were 

 wormy. Figure 2 is a photograph of an average lot of untreated King 

 apples. These untreated apples are smaller than the treated ones,
