Fic. 4—Ornamental plantings at the Northern Great Plains Field Station 
The Quercus, Celtis, Ostrya, Juglans, and some of the Ulmus 
species suffered severely from winter injury, and most of them died 
the following spring. The rest, with the exception of Acer plata- 
noides, which died after the second year, have made splendid growth 
and apparently are doing well. 
The following species or varieties were added in 1916 to the plant- 
ings, and all have made good growth:
