 Fig. 3 : ) For the growth of the first 70. years the radial curve shows 

 a convex type, for that of the following SO years, a straight line, and 

 for that of the last 100 years, a conca" . : thus we got three 



types of curves from one and the same c.

majority of which showed the growth of less than 100 years, and had 

 the type of growth of the planted tree : while in older or wild trees. 

 the type was a complex one. The material No. X one of the lar_

institute of our University. Unfortunately, we can not tell its actual 

 age. because we miss the central portion owing to it but the 



central hollow portion may be estimated to be about 200 Years, bv 

 comparison with many other trees, and the whole age will be about 

 years, the outer 1400 years beinsr the actual counting. The radial
