white pine. Altho it does best on a moist, porous soil, it will 

 make a very satisfactory growth on relatively dry situations. 

 The tree is more intolerant of shade than the white pine, and, 

 consequently, should not be planted under the shade of other 

 trees or along with other species which grow faster and may 

 overtop it. 



The Wood : The wood of the red pine is light, close 

 grained, relatively hard and of a pale reddish color. It is of 

 less technical value than the white pine, principally because 

 of its dark color and greater hardness. It is used in general 

 construction work, for box boards, lumber, piling and for 

 numerous other purposes. In Iowa the consumption of this 

 wood is much less than for the white pine. 



Planting*. The red pine has not been extensively planted 

 in Iowa, but its worth should make it a desirable tree for many 

 localities. 



For windbreak and shelterbelt planting the tree equals in 

 desirability the white pine except for the prejudice of some 

 people against the coarse appearance of its foliage. Space 

 the trees 8 to 10 feet in the rows and the rows 10 to 14 feet. 

 One of the spruces (Norway or Black Hills) would make a 

 good associate for the red pine if planted in alternate rows. 

 The spruce being slower in growth and capable of withstand-
