which may result in the formation of terminal buds indi- 

 cating the passing of the tree into a dormant stage. Where 

 this occurs before the close of the normal-growing season

 sirable, producing a weak and abnormal condition. Such 

 trees as may have this extra growth can easily be detected 

 by the formation of the terminal bud rings with a few inches 

 of lighter colored wood beyond.
