of Group I, and the 391 orchards of Group II. The typical size of or- 

 chards in Group II is 2 to 3 acres, while that of Group I is 5 to 6 acres. 

 The number of orchards of 2 acres in Group I, however, is but one less than 

 the number of orchards of 5 acres. We may consider, therefore, that the 

 mode* in size of orchards in this county is 2 acres. The median (t}'pical 

 size) in both groups is 5 acres. The mean acreage in Group I is 7 to 8 

 acres, and in Group II approximately 7 acres. In general, therefore, the 

 distribution in Group I follows that of Group II and may be considered 

 representative of the orchards of the county. Plate III represents graph- 

 ically the distribution of orchards according to size. 



Relation of size of orchard to yield and income 



In tabulating the results of the survey, the general run of the figures 

 seems to show that the smaller orchards yield better returns per acre 

 than the larger orchards. Table 4, showing the relation of the size of 

 orchard to yield and income, is based on the four-year average yield and 

 income per acre in order to avoid the yearly fluctuations. The figures 

 for the single-acre classes fluctuate considerably. The 4-acre class 

 (Table 3), especially, is misleading because three out of the sixteen or- 

 chards of that class yielded practically nothing. The general trend of 

 the results is more clearly shown by arranging the orchards into classes 

 of 3 acres as shown in Table 4. The averages there given are for orchards 

 of I to 3 acres, 4 to 6 acres, etc. The influence of the low yield of the 

 orchards of the 4-acre class (Table 3) is shown in the mean for the 4-6- 

 acre class (Table 4), namely 60.3 barrels, the averages for the 5-acre class 

 and the 6-acre class (Table 3) being approximately 63 and 64 barrels per 

 acre respectively (shown in original data not here presented).
