THEIR AUTUMN GLORY 



according to the number of species and individuals 

 associated together in a particular spot. But the 

 greatest display of colour is seen when the neigh- 

 bourhood is sprinkled with trees having evergreen 

 foliage, when it often happens that a relatively small 

 area of woodland appears decked in all the colours of 

 the rainbow. 



The most casual observer knows that all trees 

 do not assume tinted foliage in autumn. Some, like 

 the Alder, the Locust (Robinia), the Elder, and most 

 Willows exhibit little or no change save, perhaps, a 

 number of yellow leaves scattered through the green

 and only adds additional contrast to the landscape. 

 Again, plants whose leaves are covered with silky or 

 woolly hairs or with a felted mat of hairs never 

 present any autumn colouring, and in those in which 

 the green colour disappears the change is to pale 

 gray and white. 



In a rather large group of trees which includes the 

 Walnut, Butternut, Catalpa, Elm, Hickory, Chest-
