FIRST LINE OF EXPOSURE 17 



first shelter to the trees in the belt (see illustration 

 No. 3). 



The hedge is shown as a dotted line on the 

 inner side of the boundary line on the eastern 

 side (diagram No. 6), and is continued all round, 

 forming the boundary on the western side of the 

 belt. 



The boundary fence on the north, east, and 

 south is not continued all round the belt, for the 

 reason that on the western side the trees would 

 not be so exposed to strong, cold winds, and a 

 hedge alone might be considered quite sufficient 

 as a means of shelter. But it must be under- 

 stood that this is only conditional. In some 

 positions it might be necessary to provide a 

 better means of shelter from the west, as being 

 the most exposed side. 



The method of planting is also shown on the 

 plan (No. 6), which is explained as follows : 

 Very thick planting of the hardiest kinds of trees 

 (see Chap. VI. p. 52) is a requirement in the first 

 line of exposure, so that a dense mass of growth 

 of branches and foliage is formed to catch and 

 break up the first force of the gales. On the 

 Belvedere estate, thick planting has been con- 

 sidered so essential that deciduous trees are to be 

 seen growing from two to three feet apart, the 

 clumps forming almost impenetrable thickets. In 

 the less exposed parts, in wide belts or large
