 observed, after traveling over a plain in winter, that if 

 one enters a forest the temperature is much more moder- 

 ate, apart from the protection from the winds which the 

 forest affords as a mechanical harrier to their violence. 

 This greater warmth engendered by tree planting spurs 

 the adjoining vegetable growth, while the maturity of 

 fruits and grain is not so much checked by cold at night 

 and at other times. 



Besides this actual mitigation of the temperature, 

 trees, by checking the force of the winds in this way, also 

 conserve the water in the soil by minimizing evaporation. 

 All know how much more quickly an article will dry in 

 even cold wind than it will hanging quietly in the warmest 

 sunlight. Wet roads will dry much more speedily from 

 wind than from sun action. 



After the rain has fallen, water stands visibly around

One of the secondary, but important, results of the

 and the attendant train of ill which follows deforestation. 



Some fifty years ago, Commodore Matthew Fontaine 

 Maury (well known as the Christopher Columbus of the 

 Gulf Stream) found the national observatory at Washing- 

 ton unwholesome, those living there suffering continually 

 from fever and ague. To remedy this condition he planted 

 large fields of sunflowers, and, though the Potomac malaria 

 made the fever and ague extensively prevalent in the city 

 generallv, none of those living at the observatory, or in 

 the vicinity of the sunflowers, were so attacked.

It mav he remarked, parenthetically, that trees are the 

 homes of birds, and, to say nothing of the eesthetic charm 

 of their beauty and song, birds free the fields from insects 

 and from bugs to such an extent that they deserve to rank 

 high in the list of the farmer's friends. It is probable that
