it is fast growing in disgrace, this tribe is the 

 best substitute. This kind seldom exceeds 

 fifty feet high, is generally round-headed, 

 with an inclination to become flat. The 

 finest specimen at Bartram is fifty-five feet 

 high and fifty-four inches in circumference. 



It thrives best in a cool, deep, and rich 

 loam; and is best propagated by sowing the 

 nuts about four inches apart, in rows, early 

 in spring, covering them about two inches 

 deep. They are in general difficult to trans- 

 plant, and the sooner they are removed to 

 their final positions the better. They also 

 take easily by grafting on each other. * & 



2. J. NIGRA, Linnceus. Leaflets about fif- 

 teen, ovate lanceolate, nearly heart-shaped 

 at the base. Fruit globose, dotted, spongy. 

 Nut nearly round, wrinkled. Black walnut. 



This is a larger tree every way than the 

 preceding, and the handsomest of the group. 

 It is somewhat round-headed, but frequently 

 quite cylindrical, or even conical. They 

 should always grow by themselves, on ac- 

 count of their unneighborly propensity of 

 injuring everything growing about them. 

 The finest Bartram specimen is eighty feet
