ing in America, and this has recently come into pro- 

 fuse bearing on the Burbank experimental farm, eight 

 miles from Santa Eosa, California. According to good 

 authority, this Japanese walnut not only attains its 

 greatest perfection in this favored climate, but it thrives 

 equally well in countries too cold for the common 

 walnut, /. regia. In its wild state in Japan, the Juglans 

 Sieboldiana (whose curious raceme of nuts is shown in 

 Fig. 80) makes a wide-spreading tree about fifty feet in 

 bight, with pale, furrowed bark ; nuts an inch and a 

 half long, with a diameter one-third less, and a kernel 



having much the 

 flavor of the com- 

 mon walnut. The 

 tree bearing so 

 thriftily on Califor- 

 nia soil, suggests its 

 \ possible value as - a 

 » marketable nut, 

 while it already fur- 

 nishes a remarkable 

 addition to horticul- 

 tural interests."
