University of Chicago). And its high resistance 
to plagues,.drought, and its consistently healthy 
and vigorous habits and growth make it seem that 
NATURE created this variation to help achieve 
the ecological balance necessitated by the new 
tree plantations on former grass lands.

dies, most people will find it unusual and begin 
to search for outside forces that killed it. Many 
New England elm trees which have been thought 
to have succumbed in recent years to one of the 
elm plagues have died rather of old age; and 
many of the deaths in the Middle West can be 
attributed to a natural adjustment of an eco-

TREEVPLANIING 
Surely there must be a purpose and program 
in order to plant memorial trees. John Greenleaf 
Whittier said that “the wealth, beauty, fertility 
and healthfulness of the country largely depend 
upon the conservation of our forests and the 
planting of trees.’ To impress this truth upon 
the minds of the young, the Nebraska State Legis-
