ing the past spring has not come into bearing. At the Uni- 

 versity Farm the Early Harvest blackberry proved an abundant 

 yielder; and in fact, it was the only one of a collection of ten 

 varieties that bore a satisfactory crop. The Gregg and Kansas 

 black cap raspberries bore fairly good crops, while the red 

 varieties set only a few scattering fruits. 



NEW FRUITS 



A number of little known fruits and nuts that appear prom- 

 ising under Arizona conditions are being tested in different 

 parts of the State. Among these are the jujube, Feijoa, loquat, 

 white sapote, Hovenia, medlar, pistach, guava, paw paw, and 

 avocado. The jujube and Feijoa have done well at the Yuma 

 and Salt River Valley farms and at the University Farm, the 

 former bearing fruit the second season from planting. The 

 white sapote was killed to the ground during winter at the 

 Salt River Valley Farm the second year from planting, but at 

 the Yuma Farm it has not been injured by cold. The avocado 

 stood the winter temperatures at both the Yuma and Salt River 

 Valley farms but died during the summer. It has been difficult 

 to get the loquat to succeed in summer under ordinary field 

 conditions. 



GRAPE ANALYSES 



Very interesting and valuable data are being obtained from 

 samples of grapes secured from different parts of the State and 

 tested for their sugar content. According to the Balling test, 

 about one-fourth of the crop in some vineyards in southern Ari- 

 zona had a sugar content of twenty percent on June 30, 1921. 

 It thus appears that grapes grown in southern Arizona mature 

 considerably earlier than the same varieties do when grown m 

 some other commercial grape centers. 



VARIETY TEST OF BEETS 



The results of a variety test with beets are given in Table 

 VII. Cooking tests showed the Basano to be of superior 

 quality, in point of flavor and texture, to the other varieties, 

 with the crimson Globe a close second.
