 This is judged by the thickness of the xylem for 1941. 

 Multiplicity decreases outward on the branch.

TTC 34-5 (table 58) was frozen artificially May 18, 1941, and 

 was cut from the tree November 29, 1941. Multiplicity decreases 

 outward in general. In 1939, the mostly sharp, complete, entire 

 growth layer at 50.5 cm. changes to a mostly sharp lens at 42.5 cm. ; 

 to a mostly sharp, complete, entire growth layer or a long lens at 35.5 

 cm. ; and to divided densewood at 27.5 cm. The situation of 1939 at

35.5 cm. is of interest because some of the sections show a mostly 

 sharp, complete, entire growth layer, whereas others show a long, 

 mostly sharp lens. In the 1940 increment, at 35.5 cm., the lens is 

 concurrent.
