196 FOREST TREES. 



United States. The growth is slow, but if they should 

 be grafted into the black walnut or shagbark with suc- 

 cess, their cultivation would be an object worthy atten- 

 tion. 



The Pig-nut, has a productive growth, and furnishes 

 timber of equal or greater strength, than any other species 

 of the walnut. The fruit is small with a thick shell, not 

 agreeable, and of our course of little value, except to re- 

 produce ils kind. 



This tree grows through an extensive range, and south of 

 Vermont and New Hampshire, is common in every part 

 of New England. 



Bitter-nut is a common tree in various parts of the 

 United States. It rises to the height of seventy or eighty 

 feet, and furnishes timber of some value, though of less 

 than most of the species ju-t mentioned. The nuts are 

 small, with thin shells and disagreeably bitter. 



It will be concluded from this slight description of a 

 few species of the walnut, that they are an important arti- 

 cle of the natural growth of the United States. Although 

 the properties of the two general divisions in this genus, 

 do not resemble each other, and of course the timber of 

 each is fitted for different uses, all are of great value in 

 the arts, and deserve both preservation and cultivation. 



The hickories resemble each other in the size, form 

 and general appearance of the tree, arid in the quality, 

 and of course the uses of the timber. The timber of each 

 possesses great weight, strength and flexibility, but are 

 all subject to rapi I decay, when exposed to heat and 

 moisture, and are attacked and nearly consumed by worms. 



Botanists have described fourteen species of maple, 

 seven of which belong to America. They are among the 

 most lofty and beautiful trees of our forests, and grow in 

 great abundance over a large extent of territory. They 

 extend on both continents to northern latitudes, and 

 flourish well in the coldest, hardest soils. 



The different species of maples are not only among 

 the greatest ornaments of the forest, but are applied to 

 numerous important uses in the arts.
