As the above Tables will show, the species tested are arranged 

 according to the suitability as timber in the following order: — 



1. Hinoki. 



2. Akamatsu. 



3. Sugi. 



4. Asunaro. 



(11) Modulus of rupture differs according to the size of the beam 

 tested. Assuredly, beams of smaller breadth and thickness are stronger 

 than those of larger breadth and thickness.
