78 Hints on Landscape Gardening 



has so far not been applied to avenues, but from 

 which I expect the best results, especially in a 

 sandy region like ours, I run a furrow, wide or 

 narrow according to the locality, along both 

 sides of the road, which, following the English 

 way, slopes toward both sides with subterranean 

 drainage where necessary and a few side gutters. 

 This furrow is closely packed with young trees 

 as in a grove, mixing in with them here and 

 there groups of larger trees which form a kind 

 of continuous, irregular avenue rising above the 

 undergrowth. Where I do not own the adjacent 

 ground, I continue these high groups without 

 the undergrowth in a narrow strip along the 

 road. (See Plate IV, ^.) The trees are generally 

 treated as undergrowth or underbrush and are 

 pruned every six or ten years, while the larger 

 trees are left to grow undisturbed. In this way 

 even barren regions will soon appear attractive 

 when seen from the road ; and a variety of effects 

 may be produced subsequently by various differ- 

 ent modes of treatment, allowing larger masses 

 to grow high, carefully trimming some of the 

 older trees, keeping others down, etc., or, finally, 

 the landscape, where it is unattractive, may be 

 hidden by a wall of greenery. Should some of the 

 larger trees that have been set out die off in the 

 course of time, or not thrive well, the neighbor- 

 ing trees may be allowed to grow up, and in this 

 case any kind of tree that thrives well may be 

 used. This mode of treatment will do away with 

 unsightly bare spaces and make a natural avenue
