XSC 9-4-0' {1938-1941) 

 7 see + I dee + I sL + i msL +1 dL + i ddw + inc L — 3* years. (See 

 table IIS, P- 171-) 



Branch XSC 9-4 was cut off June 14, 1941, after having been 

 frozen artificially on May 9, 1941. One see plus an inc L constitutes 

 1941. 



XSC io-2-a (1938-1940) 



3 see 4- 2 psce 4- i dee +1 sL 4- 2 msL 4- 2 psL 4- dw — 3 years.

 2 see 4- 1 msce 4- 2 psee + i dee 4- i sL 4- 2 dL 4- i d ^L + i ddw — 3 years. 



In XSC ii-2-a, the 1939 increment is terminated radially outward 

 by the i msce. Poor annual contacts are by no means a rare feature. 



XSC i2-i-a (1938-1940) 



6 see 4- I msce 4-isL + 2dL4-i d^L + i ddw + i dw — 3 years. (See

 p. 177.) 



Branch XSC 13-1, as summarized above, appears to have one extra 

 see in the three years. This is not true : 1938 has 3 msce + 1 psce 4- 1 

 sL+i ddw, whereas 1939 has 3 sce4-i dee. 



XSP 1-2 (1936-1940) 



a. 6 see 4- 1 sL 4- I ee 4- 1 ddw — ? tf — s years. 



The ce of XSP 1-2 makes up the outer growth layer of 1940. Its 

 densewood is feeble and intermittent because scattered radial columns 

 of cells do not become narrow radially. 



Sections h (1939-1940), 29 cm. outward from a, can be summarized 

 as: 



b. 3 see 4- 1 sL 4- I ee — 3 tfs — 2 years. 



XSP 2-i-a (19 36-1939) 

 6 see 4- 2 dL 4- ares 4- 1 ddw— 4 years. (See table 131, p. 180.)
