THE RANGE OF BLACK WALNUT 



That there is a considerable quantity of walnut still left in the 

 country is due to the immense area on which the species grows 

 and not to the presence of large supplies in any one region. 



tender tree and will not endure the cold of our northern 

 winters. Even if its fruit was less valuable it might 

 still be planted for its wood, which supplies the famous 

 Circassian Walnut lumber so widely known and so high- 

 ly prized in the furniture business throughout Europe 

 and America. In addition to these economic values, this 

 tree also has merits from an ornamental point of view, 

 since it has an attractive bark and beautiful foliage. 



Another Walnut which is occasionally introduced into 

 the United States is the Japanese Walnut. It is a small 

 tree of the Butternut type, and promises to become quite 

 profitable in the re- 

 gions where the Eng- 

 lish Walnut is not 

 hardy. It is a prolific 

 bearer and its fruit is 

 said to be superior to 

 that of our native 

 walnuts. 



Ihe Walnuts as a 

 group tend to vary 

 and inter - cross, and 

 consequently many 

 natural hybrids have 

 been produced. New 

 and better kinds of 

 Walnuts will undoubt- 

 edly be propagated by 



h o r t i c ulturists 

 from time to time 

 but it behooves 

 us all to keep on 

 planting the old 

 kind, especially in 

 the regions where 

 they are native. 

 We may thus 

 atone for some of 

 the sins of our 

 forefathers, who 

 stiipped the land 

 of the first and 

 most valuable 

 VValnut crop, and 

 u n f o r t unately 

 were not able or 

 willing to provide 

 for another crop. 

 Walnuts are 

 not hard to grow. 

 It is recommend- 

 able, however, to 

 plant the nuts 

 rather than seed- 

 lings, for during

BERED PITH 



An almost infallible distinguishing charac- 

 teristic of the black walnut is its cham- 

 bered pith, readily discovered by splitting 

 a twig lengthwise or cutting into it, as il-

planting the little 

 trees the tap-root 

 is very apt to be 

 injured, and 

 sometimes the ef- 

 fect of such injury may continue to interfere with the 

 tree's growth for many years. Considerable work has 

 already been done in the establishment of walnut plan- 

 tations in the United States. Many fine groves can now 

 be seen throughout the country. Boy Scouts have been 



doing good work along 

 this line, and many of 

 the forest organiza- 

 tions throughout the 

 country have also taken 

 up the work. In 1919 

 more than 150 bushels 

 of Black Walnuts were 

 planted in a single nur- 

 sery in southern Penn- 

 sylvania, and in 1920 

 more than 200 bushels 

 of Black Walnuts were 

 planted in the nurser-
