78 SEEDS AND I'LANTS IMrORTED. 



of propagation is to graft the pistaclie on the terebinth tree {Pislacia terehinthus) , a 

 near relative of the pistache, native of the Mediterranean countries where the pistache 

 is cultivated. It is preferable to grow the terebinth trees from seed in place in the 

 orchard, but they can be transplanted, if necessary. The present importation com- 

 prises three-year-old trees which were grafted in nursery rows and dug up early in 

 March. 



"The pistache will endure a temperature of from 10° to 20° F. It is about as hardy 

 as the fig and olive, possibly rather hardier. Its crop is not so liable as that of the 

 almond to injury by late frosts, because it fl(jwers much later in spring, a matter of 

 great importance in the Southwest, where the almond is often injured because of its 

 habit of blooming early. The pistache thrives best on a deep soil containing lime, 

 but it succeeds also on other soils. A warm southern hillside is the best location. 

 The tree is adapted especially for culture in regions having a dry summer season. It 

 requires about the same climate as the olive, and will doubtless succeed in parts of 

 California, Arizona, and possibly in some regions in Florida. Around the shores of 

 the ^Mediterranean, where it is commonly cultivated, the tree is not irrigated. It 

 needs about as much water as the olive, and, like it, can succeed on hillsides too dry 

 to support most other fruit trees. 



"The trees comprised under this number are female trees, and should be planted 20 

 to 25 feet apart, with a male tree (No. 6350) in the center of the group of females. 

 The grafts should be cut back to two buds. The trees should be watered judiciously 

 this season until properly started, after which no special care is necessary. Although 

 these trees are already older than is desirable for transplanting, it is hoped that by 

 care, they can all be made to live, and that a small quantity of nuts will be produced 

 year after next. The trees will bear full crops when they are 7 years old. The 

 average yield is about 20 pounds." ( W. T. Swingle and D. G. Fairchild.)

"Plants of a verv large, thin-shelled walnut Avhich grows in the mountains of 

 Karpenisi, Southern Thessaly. I did not see specimens of this nut, but heard that 

 an unusually large one from one of these trees w^as sent to the Paris Exposition of 

 1898. It was so thin shelled that it was necessary to pack it in cotton. Mr. Xantho- 

 poulo, who secured the plants, says he took them from the original trees in Karpenisi 

 which bore the giant nuts sent to" Paris. ' ' ( Fairchild. )
