22 TREES AS GOOD CITIZENS 



so unfortunate as to be denied the grateful shade of tree- 

 lined thoroughfares. 



In addition there is a different stimulus produced on 

 the nervous system by the various colors. The effect of 

 green is soothing, so that foliage masses tend to counteract 

 the irritating effect of many of the colors common in city 

 streets, especially that of red brick buildings. 



What has been said for trees in the city holds equally 

 well for the open country, although, to those familiar 

 with country conditions in the eastern United States 

 a country lacking in trees can hardly be realized. In nat- 

 urally treeless regions, tree masses are also valuable in 

 protecting small areas from the sweep of the drying 

 winds and making possible the growing of plants, not 

 otherwise practicable, as well as making living conditions 

 more comfortable. 



From every point of view, shade trees are of vast im- 

 portance to the dweller in city, town or country. In 

 beauty, in comfort and in public health the shade tree is 

 the indispensable and never failing friend of man.
