WEDNESDAY, JUNE 28TH, 1916 AFTERNOON SESSION. 



At 2 o'clock p. m. the meeting was called to order by Mr. 

 Harry T. Kendall, chairman. 



The Chairman : It is going to be necessary, gentlemen, for 

 Dr. von Schrenk and Mr. Sterling to leave the meeting early 

 today to fill some engagements they have. I am going to ask 

 Dr. von Schrenk to read a few of the questions he has, and 

 answer them. Mr. Sterling has only one question that has been 

 referred to him. Now, in case any other questions occur to you, 

 gentlemen, that we might properly ask either Dr. von Schrenk 

 or Mr. Sterling, I wish you would present them. Dr. von 

 Schrenk ! 



Dr. von Schrenk : The question is asked : 'Ts the strength 

 of pine lumber affected, when tapped for turpentine?" 



The answer to that is, that it is not. Turpentine or rosin in 

 a pine tree is an excreted product. In other words, it is a 

 product that is formed by the pine tree as a result of the growth, 

 which the pine tree, so to speak, wants to get rid of. It is 

 produced in resin canals, and when the tapping operation takes 

 place the only rosin or turpentine which flows from the tree 

 comes out of the sap wood. No turpentine ever forms from 

 heart wood. So the presence or absence of turpentine in the 

 timber has no significance as far as its strength is concerned. 

 That has been demonstrated very thoroughly by a great many 

 tests which were made years ago by the United States Forest 

 Service, and has since that time been substantiated time and again. 



"Does creosoted silo stock cause the ensilage to become 

 poisonous and injurious to the stock?" 



It does not. Practically all authorities on ensilage deal 

 very thoroughly with that particular phase. A great many 

 creosoted silos have been used in various parts of the country 

 and the cattle seem to take the ensilage right close up to the 

 creosoted side, just as readily as from the center itself. 



"How long will a heart-sawn pine shingle last?" 



That depends. It will last anywhere from two to forty 

 years, depending upon the conditions in which it is placed, the 

 character of sawing, the amount of rainfall in a particular region. 

 It is practically impossible to give that a definite or specific 

 answer. Under ordinary circumstances I should say, ten or 

 twelve years would be a very fair estimate; but that should not 

 preclude its lasting very much longer, or very much shorter.
