 growth) 



Buds largely 

 killed, bark 

 and cambium 

 taken near 

 ground se- 

 verely in- 

 jured. The 

 very young- 

 est wood 

 showed little 

 or no injury. 

 In the wood 

 near the 

 ground, the 

 browning was 

 uniformly dis- 

 tributed. In 

 wood higher 

 up the brown 

 was irregular 

 and in spots. 

 In the young 

 wood, cam- 

 bium appear- 

 ed normal 

 only cortex 

 injured.

 The most 



s e ve rely 

 browned sec- 

 tion was 2 ft. 

 aboveground, 

 at the crotch 

 of a rapidly 

 growing 

 branch. The 

 section at the 

 ground was 

 less injured 

 than the one 

 1 foot above.
