The Olive; in Arizona 517 



came out again the following year. The trees have succeeded re- 

 markably v^^ell considering the rather unfavorable soil conditions, and 

 have seldom failed to set good crops. Typical fruits of these varieties 

 are illustrated in Plates I, II, III, IV, and V. 



A detailed description of the varieties tested by the Arizona Ex- 

 periment Station at Tucson is given below. The measurement of the 

 fruit was obtained by securing the average of a large number of 

 typical specimens. 



mission 



Fruit of medium size, 12 x 16-sixteenths of an inch, broadly oval, 

 tending slightly to conical, oblique, borne singly or in clusters, and of 

 excellent quality; flesh very firm and withstanding comparatively 

 rough handling; season of ripening from the latter part of October 

 to December, the fruit not dropping readily. Tree large, very vigor- 

 ous, hardy, blossoming from April 10 to 25, partly self-sterile. Self- 

 sterility is overcome by interplanting with other varieties, particularly 

 the Manzanillo which is often used for this purpose in Arizona. The 

 Mission is the leading variety for ripe pickles and oil. 



RAZZA 



Fruit of large size, 14 x 20-sixteenths inches, ovate, tending to 

 oblong, of inferior quality and dropping badly after maturity; season 

 of ripening from early October to the middle of November. Tree 

 hardy, large, vigorous, blossoming from April 5 to 20, self-sterile. This 

 variety does not make satisfactory ripe pickled olives, but may be used 

 for green pickled ones. 



MANZANILLO 



Fruit above medium size, slightly larger than that of the Mission, 

 14 X 18-sixteenths inches, from almost round to slightly oval, ripening 

 and coloring uniformly, and with very good flavor ; flesh less firm than 

 in the instance of Mission olives, and hence the fruit requires more 

 careful handling; season of ripening from the middle of October 

 to the middle of November. The fruit drops badly if the picking is 

 long delayed after maturity. Tree of medium size, less vigorous and 

 less hardy than the Mission; heavy annual bearer, and blossoming 

 about the same time as the Mission, April 10 to 25 ; self-fertile. This 

 is an excellent olive for ripe or green pickles, ranking next to the 

 Mission, and is the kind so extensively used for pimento olives.
