damage in thin open plat, than in plat 1, where the Box Elders 

 overshadow it with their shade. None of the trees have died 

 this season, and the tree, thus far, seems to withstand this 

 climate well, once it gets established. The Birch is a dense 

 shade tree, allowing no weeds to grow beneath it. Thus far no 

 deleterious effects from using hard woods entire, in this plat, 

 can be noticed. Whether or not they will continue to thrive as 

 well as they would with soft wood neighbors remains to be seen 

 as growth continues. It will be noted from the table that the 

 annual growth of the Yellow Birch has increased each year. 

 The trees now average about 9| ft. in height, the largest being 

 13 ft. high, with a diameter of 3-| in., one foot from the ground. 



WHITE BIRCH. 



For the four seasons since the plantation was begun, the 

 growth of the White and Yellow Birch has been nearly parallel, 

 some years the balance of growth being in favor of the one, and 

 again, in favor of the other. This season, the White Birch has 

 made less growth than has the Yellow.. The largest White 

 Birch is 12 ft. high, and 3^ in. in diameter, one foot from the 

 ground. The Birches succeed well, not only in the cultivated 

 plats, but as a lawn tree. The cut leaf, or Weeping Birch, is 

 one of the finest ornamental trees on the College grounds. 

 BURR OAK. (Quercus macrocanpa.} 



The burr Oaks in the plantation are yearly becoming more 

 promising. They grow very slowly at first, but during this time 

 they are making strong root growth, so that once established, 

 they withstand the trying features of our climate with impunity. 

 At time of transplanting, care should be taken not to mistake 

 live trees for dead ones, as they nearly always look dried and 

 lifeless, when taken up. During the present season, those trees 

 that have only moderate shade from the Box Elders, have made 

 a little better growth, than those growing in that section of the 

 plat, where the nurse trees are larger, and shading denser. The 

 largest Oaks in the plat are about 4 ft. in height. 



WHITE ELM. 



The Elm is one of the most desirable hard wood trees yet 

 planted'at the Station. It has few insect enemies, is a strong, 

 vigorous grower, and, year by year, proves itself more valuable.
