Important Results from Plywood Meeting 



Plywood Manufacturers Adopt New Grades and Subscribe to Big Advertising Fund 



The iiKist marked iiulication of ]jri)giess ile>'eloping from tlie 

 big meeting of the Plywood Manufacturers' Association held at 

 Cincinnati, February 8 and 9, was the preparation and presentation 

 of new grading rules which were submitted by the executive com- 

 mittee and adopted at the meeting. These rules are shown in the 

 chart carried on this page of Hardwood Eecord. The meeting was 

 one of the best ever held and great interests was displayed in the 

 various workings of the various committees. In addition the next 

 most spectacular action was the resolution to join the National 

 Veneer and Panel Manufacturers' Association, with a fund of 

 $.50,000, for preliminary work in the national advertising of built- 

 up plywoods the purpose being to eradicate the pojjular misconcep- 

 tion of the worth, utility and value of this material. 



Further action involved the appointment of a committee to go to 

 Washington for attendance at the present hearing before the Ways 

 and Means committee of the Senate in the interest of having an 

 import tariff placed on ph'woods. This is an exceedingly important 

 phase of future development of domestic plywood markets. 



Other important action was the resolution to join tlie National 

 Veneer and Panel Manufacturers' Association in its fight to put 

 docket 81ol into immediate effect. Tliis docket has been approved 



by the Interstate Commerce Commission l:)ut held up because of 

 Federal operation. It calls for the classification of all veneers ex- 

 cept mahogany as thin lumber at lumber rates. All multiple or 

 built-up woods call for ten per cent advance over lumber rates. 

 A committee was appointed to pursue this work. It was reported 

 that the second annual meeting is to be held at Chicago at the 

 Drake hotel on April 12 and 13. 



Much interesting work has transpired in' the effort to work out 

 .1 policy of standard glues. This matter came in for considerable 

 discussion at the meeting, it developing that quite a little progress 

 had been made toward this much desired accomplishment. 



An equally important part of the work of the association is the 

 preparation of the cost instruction book which is now in the process 

 of development. This work is under the su%)ervision of the cost 

 engineer who at the meeting presented the "first outline covering 

 the first work he has done. 



A discussion of market conditions developed the fact that trade 

 is still at a standstill, but an optimistic attitude was apparent 

 throughout the meeting. 



The Northern Manufacturing Company, Tippecanoe City, C, was 

 admitted to membership.
