CONDITION AND GROWTH OF THE DIFFERENT 

 VARIETIES. 



The following discussion is made on the different varieties 

 in order of their occurance throughout the plats, beginning with 

 plat No. 7: 



BLACK HILLS SPRUCE. 



This variety occurs in plats 1, 24, 29 and 30. This is the 

 first season in which the spruce has made anything like satis- 

 factory growth. In 1891, the trees in plat 1 made an average 

 growth of one inch, only a very few trees showing any tendency 

 to put out a leading branch and to develop tree form. The 

 trees of this variety in the other plats, being set that season, 

 made almost no growth. During 1892 an average growth of 

 three inches has been made by the trees in plat 1. A large part 

 of them are establishing leading branches, the longest new 

 growth being nearly six inches. The fact that these trees have 

 made three times as great a growth as during any previous year 

 is no doubt partly due to the unusually wet season. This indi- 

 cation is emphasized by the fact that, during this season, other 

 spruces in plats of two years planting made greater growth 

 than did these spruces at that stage of planting. Again, the 

 spruces in plat 1 have, during this season, made greater growth 

 than those of any of the later planted plats. This would indi- 

 cate that, as the trees become longer established their yearly 

 growth increases, and the increased tendency of the oldest trees 

 to put out leading branches, would seem to confirm this prob- 

 ability. With the exception of the Scotch Pine, the Black 

 Hills Spruce is the most promising evergreen now growing at 

 this Station. 



SCOTCH PINE. 



This evergreen occurs in plats 1, 8 and 30. Like the Spruce 

 just discussed, it makes slow growth when first transplanted,
