THE SUBJECT OF HYBRID WALNUTS 



is a fascinating one. Dr. Beadle in the 

 June number of this magazine tells how 

 Mr. Burbank, by crossing the Black 

 Walnut with the walnut of California, 

 has obtained a walnut of larger size, 

 better flavor, and parting more readily 

 from its shell than either of its parents. 

 Another remarkable hybrid was ob- 

 tained by crossing the English Walnut 

 with the California species, the resulting 



tree being of greater beauty than 

 either of its parents and only sur- 

 passed by the Eucalyptus among 

 Californian trees, in the rapidity 

 of its growth. The Vilmorin, 

 originating near Paris, in France, 

 is, however, a less successful hy- 

 brid. Whilst superior to one of 

 its parents the Black Walnut, it 

 is inferior to its other parent the 

 English or Persian Walnut. 



We come next to the recently 

 introduced 



WALNUTS FROM JAPAN AND 

 EASTERN ASIA. 



J. seboldiana and J. cordifor- 

 niis the two principal forms ob- 

 tained from Japan, andy! mand- 

 shurica from eastern continental 

 Asia, are almost the same in 

 wood, foliage and habits of 

 growth, and to quote again the 

 U. S. bulletin of 1896 on " Nut 

 Culture." " They are very closely 

 allied botanically and no distinct 

 characters seems to have been 

 noted except in regard to the 

 form, size, and smoothness of 

 the nuts, the varying thickness of 

 the shell and the quantity and 

 quality of the meat. Of the three, 

 the nut oi J. tnandshurica bears a close 

 resemblance to our butternut, while 

 that oi J. seboldiana more resembles an 

 elongated form of Persian walnut, and 

 J. cordiforjfus a small thin-shelled, 

 heart-shaped form of the same species." 

 The first trees oi J. seboldiana were in- 

 troduced into California about i860, 

 and of late years it has become quite 

 widely distributed in the United States. 

 It has been found perfectly hardy at 

 the Experimental Farm at Ottawa, where 

 it has been fruiting for the past two 

 years. The nut obtained from this
