NATURE'S OPPORTUNITY 



Health is the normal condition of the tree, just as it is of the human body. Disease and 

 decay are the result of a perversion of the natural order. A cavity in a tree is indisputable evidence 

 of neglect or abuse — it is a danger signal which, if unheeded, proclaims the inevitable death of 

 the tree. 



Examine the tree shown in the picture above. Before it was placed in the hands of the tree 

 surgeon, it appeared perfectly healthy and sound on every side except one. But there a condition 

 was revealed which startled its owner. Decaj^^insidious decay — was eating away the interior, 

 robbing the tree of its physical strength. Not only was the process of decay faster than the process 

 of healing, but there was no surface over which the bark could heal. 



The tree was placed in our hands for treatment. The decayed wood was completely removed. 

 The cavity was prepared and filled in accordance with our perfected methods. The contour of the 

 tree is preserved, as clearly indicated in the photograph above. Over this new surface the bark will 

 completely heal. The life forces are now unhampered, and another century has been added to the 

 life of a noble tree. This is Nature's opportunity. 



The owner of this tree, Mr. Gustav H. Schwab, expresses himself as follows:
