THE WALXUT. 247 



to revert to the original or tree form. This may not 

 show itself very strongly in the first generation if the 

 nuts are obtained from grafted trees of some age, but in 

 the second and third generation the early-fruiting and 

 dwarf are usually entirely lost. The only certain way of 

 securing the true variety is by grafting or layering, but 

 it is to be feared that very few trees propagated by these 

 modes are in cultivation, at least in the Eastern States, 

 although nurserymen have been offering Pra3parturiens 

 walnut trees in their catalogues during the past fifty 

 years. In one now before me, published in New York 

 city in 1844, trees of this walnut are offered at one dol- 

 lar each, or about what is charged for seedlings at the 

 present time. As nothing is said in the catalogues about 

 the mode of propagation, we infer that they are seed- 

 lings, as grafted trees would be worth more than one 

 dollar. The nuts of this dwarf 

 walnut are of medium size, thin- 

 shelled and of excellent flavor; 

 valuable for gardens of limited 

 extent. 



SEROTINA. Late Walnut, St. 

 John Walnut. A very peculiar 

 sort, inasmuch as it is the latest 

 of all to bud and bloom in spring, 

 and yet it pushes forward so rap- FIG 98 SEROTIXA OR

others in the fall. They are of medium size (Fig. 98), 

 with a rather hard shell, but the kernel is plump and 

 good flavored. The tree is very productive, and sure to 

 escape late spring frosts. 



VTLMORIN. This is claimed to be a hybrid between 

 some variety of J. regia and our native black walnut, 

 J. nigra. Scarcely known outside of France.

 Vourey, a small town in southeast France. It has much
