form, having beautiful shining foliage. It also is subject to the 

 attacks of the cottonwood leaf beetle. 



The birches are native far north, but they prefer a cool, 

 damp atmosphere, and may not, for that reason, prove success- 

 ful in all parts of the state. Many trees have died in the college 

 lawn, b'ut those that survive are in fine condition. There are a 

 few line specimens of cut-leaved birch growing in Brookings, 



Among the flowering shrubs which may fairly be entitled 

 to a share of attention in lawn planting, the iollowing have 

 proven hardy at this Station: White, common and Persian lilac, 

 mock orange or syringa, snowball, Spiraea opulifolia and Spiraea 

 Van Houtii, flowering current, purple-leaved and common bar- 

 berry, wahoo, snowberry, rugosa rose and other roses. 



EVERGREENS. 



At the last meeting of the State Horticultural Society held 

 at De Smet in December, 1890,- a number of fine specimens of 

 cornifers were exhibited. They were grown in the drouth- 

 stricken part of Kingsbury county, but in spite of three years of 

 unprecedented dry weather some species showed fine growth and 

 all were in the best condition. 



In the Station grounds the growth of several conifers has 

 been excellent, and there would seem to be no good reason why 

 at least three species should not be included in the plantations 

 of the state, and probably five varieties can be successfully 

 grown as lawn trees over the larger part of the state. The 

 hardiest of the evergreens seems to be the Scotch pine, and it is 

 also the most rapid grower, at least while young, The red 

 cedar and the white spruce, in addition to the Scotch pine, can 

 be grown in any part of the state. Red cedar is native along the 

 Missouri bluffs, and the white spruce is one of the principal 

 forest trees of the Black Hills. 



In addition to these species, which should be generally 

 grown throughout the state, balsam fir, Norway spruce and 

 arbor vitae may be successfully cultivated in the southern 

 counties. Colorado blue Spruce is quite as hardy as white 

 spruce, but it is a high-priced tree. It' can be safely recom- 

 mended as a fine species for the lawn.
