( / ) My own theory at present is that bamboos felled during November and 

 the first half of December and immediately piled or stacked in the sun will not be 

 attacked by the borers. I should like a verification of this by experiments 

 carried out in different parts of the country. 



It would lay me under a deep obligation if all who institute such experiments 

 would forward me 5 a copy of their notes and observations, together with the 

 deductions they draw therefrom.
