Can You Answer These Questions on the Gluing 

 of Wood? 



1 . At what temperature should animal glue be melted 

 and kept before using in order to reduce deterioration to 

 the minimum? What effect does a temperature much 

 above or below the correct temperature have on animal 

 glue? 



2. Can a strong joint be made with animal glue after it 

 has chilled on the wood and formed a firm jelly? 



3. What is the most desirable pressure to use in gluing 

 joints? 



4. What are the principal causes of starved joints? 



5. On which are starved joints most likely to occur, 

 white oak or birch? 



6. List in order the following glues from the highest 

 to the lowest in water resistance: high-grade animal, blood 

 albumin, casein and vegetable. 



7. What are the chief causes of wrarping in plywood? 



8. What causes sunken joints in veneered panels? 



9. Name two detrimental effects possible from heating 

 wood before gluing. 



1 0. Will tooth planing the wood before gluing make a 

 stronger joint? 



These are just a few of the points that will be discussed 

 in the short course of instruction in the gluing of wood 

 which will be given at the United States Forest Products 

 Laboratory, Madison, Wis., September II to 16, 1922. 



A Comprehensive Book on Glue 



The manufacturer of plywood or of veneered products should 

 find much both interesting and instructive in the book on "Modem 

 Glues and Glue Handling," written by Clyde H. Teesdale, A. B., 

 and C. Mortimer Bezeau. The title of certain chapters, "Glue 

 Room Equipment," "Veneering Scroll Work," "Laying Fine Face 

 Veneers," suggest the value of this book to the wrood\vorking estab- 

 lishment using veneers. In fact, the whole subject of glue, from 

 the historical beginnings of its use to methods of selling is treated 

 comprehensively in this book. The book is published by the 

 Periodical Publishing Company, Grand Rapids, Mich. 



Allen Remains Head of Allen-Eaton Company 



W. H. Russe, who recently purchased the interest of J. Q. Eaton, 

 Memphis, and Otis A. Felger, Grand Rapids, Mich., in the Allen- 

 Eaton Panel Company, has been elected secretary-treasurer of that 

 firm. He was vice-president before acquisition of his additional 

 interest therein and he is therefore vice-president and secretary- 

 treasurer. C. B. Allen continues as president, and there will be 

 no other changes in official personnel. 



The plant is on the eve of resuming operations. Mr. Russe has 

 taken hold with characteristic energy, with the result that plenty 

 of coal has been secured, while logs are in the pond in sufficient 

 volume to enable working pretty close to capacity. Mr. Allen is 

 off now on a selling trip. Mr. Russe says that demand is fairly 

 active and that prices, while lower than they should be, are fairly 

 remunerative. 



The next exposition of Jamestown, N. Y., furniture manufac- 

 turers is to be held from October 30 to November 1 I. 



Walnut 

 that adds to 

 the quality of 

 your goods 



"Pigs is pigs," so they say. And 

 walnut is walnut. But there are 

 guinea pigs, and razor backs, and 

 Durocs, and just plain hogs. 



And there is plain ordinary wal- 

 nut and the IOWA walnut that 

 grows in the black, rich soil of 

 Iowa river valleys and grows finer 

 in texture and more beautiful in 

 marking and greater in strength, 

 just as corn grows taller here than 

 anywhere else in the world. 



Its superior quality adds to your 

 quality, and makes your goods sell 

 better.
