AN APPLE ORCHARD SURVEY OF WAYNE COUNTY, NEW YORK. 245 



The yields for 1903 were secured by letters to the growers. They 

 doubtless average too high, for those who had a very small crop some- 

 times considered it too small j;o be worth reporting. 



The records of the 1902 yields are the most complete and the most 

 accurate of all. 



Method of making the computations. Since every orchard in Wai- 

 worth was examined, all computations have been made for this town 

 by itself, and separate ones made for the south and for the north parts 

 of the county. In some cases Ontario and Macedon townships were 

 each considered separately. Nearly all these computations when 

 yields are concerned are made for the crops of 1900, 1901, 1902, 1903. 

 The conclusions have almost invariably been the same for each year 

 and for each part of the county. In this bulletin they have, in most cases, 

 been summarized under two heads, Wai worth and the remainder of the 

 county. 



In computing yields under various methods of treatment, the yields 

 of the orchards set before 1880 are ordinarily used. Trefcs set since 

 that date have mostly not arrived at maturity. 



In computing any one item the others have generally been ignored. 

 The justification for this lies in the fact that so many orchards have 

 been examined that other items will balance. For example, in deter- 

 mining the average yields for orchards having trees set at different 

 distances apart, no attention has been given to the care of the orchard. 

 There are orchards set at all distances that have been well cared for 

 and others that are neglected. The large number examined makes 

 an average of conditions. The danger of this method of making calcu- 

 lations lies in possible coordinate factors. The man who tills his 

 orchard may be the man who sprays. Some points of this kind are 

 discussed under the different chapters. To test the method, some compu- 

 tations have been made on the basis of sub-groups of orchards otherwise 

 similarly treated. The results have sometimes been changed in absolute 

 amounts, but have been unchanged in their relation to each other, or have 

 been so slightly changed as not to alter the conclusions to which they 

 point. 



The independent calculations for Walworth township and for the 

 north and the south parts of the county, furnish additional checks. 

 There are usually twelve independent calculations one for each of 

 these divisions for each of the four years. When these results all
