derneath. The fruit is large, roundish, depressed at top, the 

 green shell exceedingly thick, and separating completely into 

 quarters. The nut, Avhich constitutes but a small part of the 

 \yhole fruit, is white, angular, flattened, thin shelled, its kernel 

 greatly superior to eithei of the preceding, and in considerable 

 request. 



The wood of the thvfee foregoing species of walnut posses- 

 ses similar properties. It is hard, compact, heavy, and of very 

 great strength. At the same time it is liable to warp and de- 

 cay, especially if exposed to the weather. It is principally 

 used for purposes where strength is required, as in hoops, 

 bows, the handles of tools, &c. It furnishes one of the best 

 kinds of fuel known, and commands a higher price in our mark- 

 ets than any other species of wood

This tree differs from the hickories already described, in its 

 wood, flowers, and fruit. The leaves consist of about fifteen 

 leafets, which are lanceolate, rounded at base, serrate, and some- 

 what pubescent. The amcnts are single, not united three to- 

 gether, as in the foregoing species. The fruit is large, oblong, 

 somewhat pointed, with a viscid, adhesive surface. The nut 

 is oblong, acuminated, very rough, with deep, irregular depres- 

 sions, the kernel containing a great quantity of oil. 



The wood is lighter and weaker than that of the preceding 

 kinds, but is said to be durable. An extract made from the 

 bark is in great estimation for its medicinal qualities, being one 

 of the most useful laxatives. According to an experiment pub- 

 lished in the Massachusetts Agricultural Journal, the sap of the 

 butternut tree is capable of producing as much sugar as that of
