to 2.4 inches; while two 80-year old trees, grown in the open, were 

 55 and QQ feet in height and 35 and 24 inches in diameter, with 

 crowns spreading 50 and Q5 feet 8 to 10 feet above the ground. This 

 tendency to spread and grow into branches, behaving somewhat like 

 beech, makes it necessary to plant close, and, if possible, with even 

 more rapid growers, like ash, as nurses or admixture. The species 

 is lightneeding, hence if mixed with shady species like maple or 

 beech, these must be slow growers. 



In an 80-year old stand of 2 acres, where it is mixed with oak and 

 maple on a favorable site — deep, humase, sandy loam soil in a cove 

 with southern exposure — the 38 trees have diameters of 1 1 to 27 inch- 

 es and a height of 90 to 95 feet, with excellent form, the crown diame- 

 ters being 18 to 38 feet, and the average contents 92 cubic feet per 

 tree. The oaks and maples, planted at the same time, have hardly 

 the diameters and are lagging far behind in height. These trees 

 bear annually from 24 to 28 bushels of nuts, which showed a germin- 

 ation per cent, of 90; usually 80 per cent, is considered good. One 

 bushel weighs about 175 pounds and contains about 1,150 nuts or 

 QQ nuts to the pound, which is sold at 4.5 cents in Vienna. 



Other points in favor of the species, besides its great usefulness 

 and high price for wood, are its immunity from insects and damage 

 from game animals. It is said to be very sensitive to late frosts, 

 which is not the case in its native habitat. 



Regarding its cultivation, the following points are given: 



The most suitable soil is a deep, fresh, not too compact, mild, 

 loamy sand. The nuts, freed from the green shell, are wintered in 

 sand. [Unless planted in the fall, which is better. — Ed.] In plant- 

 ing them, preferably using nuts directly, they should be carefully 

 placed with the germinating point downward, 2 to 3 inches deep. If 

 plants are first grown in the nurseries, the pruning of the very large 

 tap root, as with all taproot trees, has the effect that at least for two 

 years the height growth is retarded. Though lightneeding, it re- 

 quires in its youth side protection and partial shade.
