242 ELEMENTS OF AGRICULTURE 



trees is often the first object. Miles and miles of road 

 stretch away without so much as a bush to shield the 

 traveler from the fierce summer sun. The idea prevails 

 that trees keep a roadbed damp, but this is true only 

 where the soil is naturally very damp. A properly 

 constructed road is never injured by shade trees, but on 

 the other hand is made very much more comfortable 

 for travelers. 



Xo pasture should be without its group of shade 

 trees; if unprovided with shade, animals suffer very 

 much from the summer sun. In the heat of the day 

 they love to collect in the shade of some tree and wait 

 for the cooler hours of the day, during which they feed. 

 No pasture is complete without its shade trees for the 

 protection of animals during the heat of the day. 



For ornamenting and shading the grounds about 

 dwellings, trees are often grown, and for this purpose 

 various kinds of trees and shrubs are used according 

 to the fancy of the owner. No country home is com- 

 plete without its setting of ornamental trees or shrubs, 

 and the market value of a place may be increased by a 

 growth of trees or shrubs about the house.
