ing from two to forty-eight hours. The reducing sugars were then 

 deteraiiiied. 



On the day that tree niimber 5 died, or rather ceased to flow sap, it was cut 

 down and two sections, one about 35 centimeters from the top and the other about 

 40 centimeters from the ground, were immediately brought to the laboratory and 

 analyzed. 



The dimensions and the weights of the sections were:

Volume 2.71 cubic meters. 



Borings were taken from the center and from points 2 centimeters from the 

 outer edge of both the top and bottom sections and analyzed, with the following 

 results :
