Oak, Pin Oak. 



This rapid-growing oak with its beautiful 

 trunk has been grown as a forest tree in certain 

 small areas in the Rhine province, Wiirtteinberg, 

 and Hungary, and it is on record that the pin 

 oak has attained, in 48 years a height of 21*3 

 metres and 44 centimetres in diameter, compared 

 to the pedunculate oak with a height of 16-9 

 metres and diameter of 36 centimetres. The 

 trunk and contents of the pin oak was 1^04 f.m., 

 and of the pedunculate oak only 0*49 f.m.

 oak, but the tanning properties of its bark are 

 quite equal to it.
