activities to work out a thing on a laboratory scale, and then we 



go ahead and show it can be done commercially. The first step, 



of course, is to work it out in the laboratory, get your data, and 



then co-operate with some commercial concern that manufactures 



some similar product on a large scale, and test out the ideas for ** ow th ^ 



commercial work. Now, this satchel I have here, except for the ice Experts" 



corners, is made out of wood. I paid a dollar for it. Before the 



war I bought it for fifty cents. Since the war the price of all 



paper products has gone up tremendously. 



A product you are very familiar with, no doubt, is wall board. 

 I have several different kinds of wall board that can be made 

 from wood 'waste. Here is one that is extraordinarily light 

 lighter than cork. That is being used extensively. Here' is a 

 board that is much heavier very strong and stiff. There is a 

 wall board made from wood waste, absolutely fireproof. This 

 particular product goes largely into the construction of sailing ves- 

 sels, because of its lightness and fire resistance. It is used in 

 building ceilings and partitions of sailing vessels. 



Here is a new use of wall board which is coming into rather 

 extensive use making blackboards out of this wall board. It 

 is nothing but wood, ground up fine, run over a machine and, 

 pressed into a board, and then covered with a light crushed stone, 

 which is rolled in. And they make this in dull green, which is 

 claimed to have a more soothing effect on the eyes of the school 

 children than black. It is being used quite extensively. 



To show you the extent to which some of the manufacturers 

 of these products go, I show you this, which you readily recognize, 

 and which is being distributed to a lot of the hotels in the United 

 States, to hang up your coat in the hotel, and really is meeting 

 with quite a favorable reception. 



Now, here is some of this class of wrapping paper that we 

 made ourselves from long leaf pine. This particular quality I 

 have here is considerably stronger than the best grade of wrap- 

 ping paper that is now being made in the United States, and com- 

 pares very favorably with the best grade of wrapping paper made 

 in the world. 



Here is twine made out of one hundred per cent wood. This 

 twine is now being experimented with by your Association for 

 tying up lath and other products, in place of sisal twine which, as 

 you know, comes from Mexico. If we can make out of this
