A. Norby, Madison, S. D., reports in Feb., 1907, on White 

 pines eighteen years planted: u The noble timber tree of 

 the northern forest, the White Pine, is not considered safe 

 in exposed places in this state, being a native of a more 

 humid section. Still, I have some nice specimens 15 to 18 

 feet, thrifty and vigorous, standing in a sheltered place. It 

 is the prettiest of pines." 



Red Pine. 



Red Pine. (Pinus resinosa, Ait.). Leaves about six 

 inches long, two in a sheath. Also called the Norway pine, 

 but this is a lumberman's term; it is purely an American 

 species and is not a native of Europe. Native from New- 

 foundland and New England westward to Manitoba and 

 Minnesota. A handsome ornamental tree of vigorous growth, 

 attaining a height of 70 feet and a diameter of two feet. In 

 open exposure at this Station the Red pine has not proved 

 long-lived, which is the general experience with it. However, 

 it endures prairie conditions better than the White pine. It 

 is not a common pine in the nurseries which may account 

 for the limited experience with it. 



A. Norby, Madison, S. D., reports his 18 years test as fol- 

 lows: "The Red pine is also a native of our northern for- 

 ests, and by some thought valuable for prairie planting, but 

 here it is not equal to our test winters, when young at least, 

 and should be planted with caution." 



Limber Pine. 



Liimber Pine. (Pinus flexilis, James). Also called 

 Western White Pine, is a tree attaining a height of 50 feet; 

 leaves, five in a sheath like those of the common White pine. 

 It is a native of the Rocky Mountains from Alberta, Canada, 

 to Arizona. It is rare in cultivation and of slow growth. A. 

 Norby, of Madison, S. D., has tested it the past eight years 

 and reports it hardy but not as pretty a tree as the common 

 White pine.
