resembling those of the butternut. Fruit globular, husk very 

 thin, nut yellowish, thin shelled. Kernel intensely bitter. 

 Wood rather soft, white, but often quite tough. A small, slen- 

 der tree of a graceful habit when allowed room for full develop-

 Canada to Florida, and westward to Texas. 



C. aqnatica, Nutt. Water Hickory. Leaflets nine to eleven, 

 oblong-lanceolate, pointed, smooth. Fruit roundish, four ribbed, 

 husk thin, nut flattish, four angled with thin shell, and kernel 

 very bitter. A small tree with rough, somewhat furrowed 

 bark. Wood similar to the last, and I may add a closely allied

C. myristleaformis. Nutmeg Hickory. Leaflets five, ovate-

 of preservation and propagation. But in our northern climate, 

 budding and grafting the hickory is seldom successful, although 

 several of my correspondents assure me that they find little 

 more difficulty in grafting hickories than they do the apple or
