Windbreaks and Shelter Trees 31 



With clean growth the fire risk would be a very small one, fov 

 we must presume the trees to be around cultivated fields, grow- 

 ing grain crops, green Winter fodder, or good grasses, and not 

 as mere divisions to the natural veld. Where they are planted 

 for veld protection it will be necessary to take the usual pre- 

 cautionary measure against fires during the Winter. Coniferous 

 trees, which will probably form the outer lines, are very inflam- 

 mable, and this portion of the break should reach right down to 

 the ground, the lower branches sweeping the soil. 



SHELTER BELTS FOR SPECIAL PURPOSES are to be planted on the 

 same general principles as those for the fields. These may be 

 wanted for orchards, dams, outbuildings, garden, or house. Trees 

 to protect orchards should be chosen for freedom from scale and 

 other diseases, and probably Cypresses and Oyster Bay Pine are 

 the cleanest.* These should be planted well away from the fruit 

 trees, fully 40 feet away from the nearest line. Trees for the 

 homestead should be kept well away from the buildings. It i? 

 more healthy to have a clear space of lawn, gravel, and yard 

 around, than to be absolutely closed in by foliage. 



When planting shelter trees for any purpose, it is wise to care- 

 fully choose the seedlings, so that all those planted are vigorous 

 and shapely. Equal and strong growth are of great importance, 

 and the whole effect, both for shelter and appearance, will be 

 spoilt if gaps occur.
