clumps, other kinds of trees may be more thinly 

 planted than those advised in Chap. VI. pp. 52-55. 



Belts of trees also should be as wide as 

 possible ; narrow belts are practically useless as 

 a means of shelter from the winds. 



In some situations round or oval clumps of 

 trees may be arranged in such a manner that 

 their total effect is similar to that obtained by a 

 single wide belt of trees, so as to break up the 

 winds on their onward course (see illustration 

 No. 7).
