evidences of the intra-annuals of 1944 are so faint that they would 

 be completely disregarded unless one knew them to be present on 

 the inner sections.

Sections at 15 cm. in TTP 20-36 (table 81) came from the middle 

 of the first 1943 tip flush ; those at 8.5 cm. came from the middle of the 

 second 1943 tip flush ; and those at 4 cm. came from the middle of the 

 1944 tip flush : In the 1943 increment the inner tip flush corresponds 

 to the one diffuse, complete, entire growth layer, and the outer to the 

 one sharp, complete, entire growth layer. In the 1944 increment one 

 tip flush corresponds to two growth layers. The relations among tip 

 flushes, diameter flushes, and years are apparent.

TTP 20-38 and 39 (tables 82-83) should be contrasted with pre- 

 ceding branches, especially TTP 20-36 (table 81).
