158 AGRICULTURAL COLLEGE BULLETINS. 



jiiiallv tlie more sym metrical and straighter limbed trees, as maples and 

 elms. 1 til ink it is desirable to plant with reference to the winter aspects of 

 deciduous trees and shrubs. 



The evergreens must comj^riso the chief attractions of winter landscapes, 

 however. A list of such as are desirable and have proved hardy at the col- 

 lege is appended. SomcAvhat similar lists as those which follow were given 

 in" a recent bulletin, but these are more complete. The climate at the 

 college is exceedingly trying on plants, and many trees and shrubs which are 

 hardy in villages in the vicinity have not endured the winters upon our 

 grounds.

XoTES. — For all purposes the Norway spruce is probably our best ever- 

 green, although it is too coarse and it grows too large for the immediate 

 vicinity of the house. In order to grow good Norways, they must not be 

 crowded by other trees, and the lower limbs must not be allowed to get 

 ragged. It is a great mistake to trim up evergreens from the bottom. Their 

 greatest beauty lies in compact lower limbs. The tree can be kept compact 

 and green to the base by heading in the branches a few inches every year or 

 two. There are many trees ujoon the grounds which are green and dense to 

 the ground, although they are twenty-five years old. These have not been 

 trimmed to such an extent as to destroy the natural form and grace of the 

 tree.
