WALNUTS 201 



names "Siebold walnut" and "heartnut" are discrimi- 

 nating enough, leaving out the word "Japanese" 

 altogether. 



The result of planting nuts from American grown 

 Japanese walnuts threatened to disturb international 

 relations at one time. Nurserymen sold young seed- 

 lings grown from such nuts as Japanese walnuts, 

 but when the trees came into bearing they bore "but- 

 ternuts" ! Were the nurserymen dishonest? Perish 

 the thought ! They had planted nuts of the Japanese 

 walnut growing in the vicinity of butternut trees, 

 and there seems to be evidence that the Japanese 

 walnuts frequently seize upon the pollen of the but- 

 ternut in preference to their own, giving us hybrids, 

 which have a tendency to show the characteristics 

 of the butternut as a dominant factor. This par- 

 ticular observation will be interesting to the biologist 

 in relation to the question of the descent of the but- 

 ternut and the Japanese walnut. The butternut ap- 

 parently represents the primitive type toward which 

 newer types have a tendency to revert in accordance 

 with organic law. The result of examination into 

 this question at least cleared honorable dealers from 

 the suspicion that they had been palming off butter- 

 nut trees instead of Japanese walnuts upon their 

 customers. 



Grafted stock of choice varieties of the heartnut 

 may now be obtained in quantity from dealers. The 

 nut has not as yet become established in the market, 

 being too new. Because of the beauty, hardiness, 

 and early bearing of the tree it should be found in
