HEDGES 
A number of kinds of trees and shrubs were set out in hedgerows 
of various lengths 10 feet apart, 1 to 3 feet apart in the row. With 
the exception of three, all were planted in 1915. Most of them are 
still growing. The most successful ones were Spiraea, Syringa, 
Lonicera, Elaeagnus, Rhamnus, and Acer. Two forms of hedges, 
those sheared or trimmed and unsheared ones, were included. 
The following is a list of the trees and shrubs planted in the sheared
