BOXELDER. 



Boxelder has but scrubby growth, and there is little reason why it 

 should be chosen where so many superior species grow well. It has, 

 however, been planted extensively as a street tree, and is still being 

 grown for this purpose. 



CHESTNUT. 



Of the two chestnut plantations examined, only that in Sangamon 

 County was originally spaced close enough to produce good form. 

 Even then the trees have been gradually dying, and the general con- 

 dition of those still standing is poor. A few good chestnut trees are 

 found in the towns, but the species is likely to winterkill in the north- 

 ern part of the State. Attempts were made to establish a block of 

 chestnut in the experimental forest at Urbana, but without success. 



BUTTERNUT. 



Of the two butternut plantations measured, that in Lee County is 

 in good condition, while that in Champaign County has done very 

 poorly. Nowhere is there any indication that the general planting 

 of this species will be successful. 



WHITE ELM. 



White elm has been planted only for ornament or for protection. 

 It does well throughout the State, and is one of the best trees for the 

 purposes for which it is planted. 



WHITE PINE. 



The white pine plantation at the University of Illinois was the 

 only one found in the course of the study which had been properly 

 spaced in the beginning, and which, accordingly, had developed as it 

 should. Its excellent growth demonstrates that plantations of this 

 species can be established successfully on prairie soil, though there 

 is little inducement to undertake them as an investment. 



White pine has been largely used for ornamental planting in parks 

 and yards, nearly always with success. It grows better in Illinois 

 than any other planted pine, and makes an excellent shelter belt. 



SCOTCH PINE. 



Scotch pine has been widely planted as an ornamental tree, but 

 has little to recommend it. It is generally short-lived and scrubby. 

 When open grown it is likely to become flat-topped. Because of the 

 ease with which it is propagated and transplanted it is a favorite 

 with the nurserymen, and with others who desire a quick-growing 

 evergreen without regard to its later development.
