The Walnut is the only tree belonging to this 

 order with which we are familiar in England- 

 It is a native of Persia and Cashmere^ whence it 

 was probably introduced before the beginning 

 of the sixteenth century. Of the Hickory -tree 

 there are many species, all natives of North 

 America, where they are greatly valued for their 

 nuts, as well as for their timber, which is of 

 great weight, strength, and tenacity. It is used 

 for various purposes, especially for cask-hoops
