 Questions 



The Chairman: As I started to say, before Mr. Hines so 

 thoughtfully provided for the vote of thanks for the Doctor, I 

 don't know how the school of salesmanship can thank him. But I 

 do think that- the people of Houston are going to be very fortunate 

 next October, when he is going to be with us for two weeks. 



Dr. Krebs : Thank you, Mr. Kendall. 



The Chairman : I wish to say that those who have not se- 

 cured banquet tickets had better do so immediately. There are 

 only four hundred tickets. No reservations will be held after 1 :00 

 o'clock, as the lumbermen of St. Louis desire to take up all of 

 the unsold seats. You can get the banquet tickets only in the 

 foyer from now on. Gentlemen, we stand adjourned until 2:00 

 o'clock and please be prompt. 



(At this point, at 12 :40 o'clock p. m., the school took a recess 

 until 2 :00 o'clock p. m. of the same day.)

Dr. von Schrenk: Does the treatment of wood increase its 

 strength and durability? If either, why? 



The answer to that is, that no treatment will increase the 

 strength. The inherent strength of wood fibre cannot be increased 

 by any process of treatment beyond that which it originally has. 

 As to durability, practically every acceptable form of chemical pres- 

 ervation will increase its durability. I will have a good deal more 

 to say in answering that question tomorrow. In general, I might 

 say that if wood is properly treated chemically, its durability may 

 be increased anywhere from twice to an indefinite length of life. 



Second question : What relation has pitch to the durability of 

 timber ? 



In general it may be said that pitch, in and of itself, has no 

 relation to the increase or decrease of the durability of timber. If 

 the pitch percentage cease at ten or fifteen per cent, or more, as in 

 cut pieces from turpentine logs, the durability would be very ma-
