112 PEACH LEAF CURL: ITS TSTATURE AND TREATMENT. 



Following the figures in the above table which .show the number of 

 peaches in 100 pounds of fruit are those giving the number of pounds 

 of fruit gathered at the first and second pickings. From these four 

 columns of figures has been calculated the number of peaches gathered 

 from the trees of each row of the block for both the first and second 

 pickings. By adding these numbers the total number of peaches 

 matured by the trees of each row was quite accurately determined. 

 To this amount is now added the number of peaches thinned from the 

 trees, where thinning was required, the grand total representing the 

 number of peaches firmly set by the trees of each row. By dividing 

 this grand total by the number of trees in a row it has been possible 

 to show the average number of peaches set per tree on both sprayed 

 and unsprayed trees, and for every row in the experiment block. 



COMPARATIVE QUANTITY, QUALITY, AND CASH VALUE OF FRUIT FROM 



SPRAYED AND UNSPRAYED TREES. 



(Pis. XI and XII.) 



The actual yield in pounds of peaches, the quality, and the cash 

 value of the fruit produced by the sprayed and unsprayed trees of the 

 experiment rows of the Rio Bonito orchard in the season of 1895 are 

 fuU}^ and accurately shown in the table which follows. This table 

 gives a full record of the yield as it was taken in the orchard, and the 

 results are of the greatest value from a practical standpoint, convey- 

 ing an accurate idea of the cash gain resulting from this spra}^ work. 

 If the reader will compare the average value of the fruit produced by 

 the sprayed trees of row 21, for example, with that of the fruit pro- 

 duced by the unsprayed trees of row 20, some conception of the 

 possible gains resulting from thorough spraying ma}^ be obtained. In 

 studying this table, it should be remembered that the results shown 

 were obtained from the use of 35 different f ormul?e and sprays. Some 

 of the sprays were of little value, others of medium value, etc., hence 

 the gains shown for the entire block are far below what they would 

 have been had the trees of each of the rows been sprayed with such 

 sprays as those used upon rows 21, 22, or others of the better-yielding 

 rows of the block.
