716 FRUIT CULTURE IN FOREIGN COUNTRIES. 



figures which in my opinion only apply to a small grove of exceptional 

 excellence are as follows : 



Pesos. 



Gross yield 90 arrobas of oil, worth 675 



Plowing Pesos.. 10 



Pruning and cleaning do 60 



Harvesting do... 75 



Pressing do... 90 



Interest and wear and tear of plant do... 100 



335 



Net 340 



From which deduct taxes (about 20 per cent, of net yield) . 68 



Leaving net income .. 272 



Equal to about $58 per acre. 



The following data, in reference to a grove of 180 aranzadas situated 

 near Ecija (province of Seville), show what, in my opinion, may be con- 

 sidered mean results of careful culture on a large scale : 



Fruit collected (in fanegas).* 



Fanegas. 



1868 1,624 



1869 1,045 



1870 2,910 



1871 2,784 



1872 6,131 



1873 2,346 



1874 1,205 



1875 1,317 



1876 5,706 



1877 820 



1878 3,076 



1879 920 



1880 8,375 



Mean annual product (equal to 16. 35 per aranzada) 2, 943 



Taking the oil yield at 15 pounds per fanega of fruit, and estimating 

 oil at 7.50 pesos per arroba (of 25 pounds), the average value of the 

 harvest per aranzada will be 73.50 pesos (equivalent to $15.28 per acre). 

 This estate previous to 1868 had not been carefully tended, And it is, 

 therefore, fairer to take the mean of the last five years (1876 to 1880) 

 as a standard, the extraordinary crop of 1880 being offset by the very 

 small yields of 1877 and 1879. For this quinquennium the account stands 

 thus: Total of five years' yield, 18,897 fanegas of fruit ; annual yield, 

 3,779 fanegas 5 annual yield per aranzada, 21 fanegas, yielding 315 

 pounds, equal to 12f arrobas of oil, which, at 7.50 pesos per arroba, 

 have a value of 94.50 pesos, equivalent to $19.66 per acre. Great 

 as is the range of estimates in relation to the results of olive culture 



* The fanega of olives weighs from 65 to 75 pounds, and yields from 12 to 16 pounds 

 of oil.
