The value of technical knowledge of KILN 

 DRYING is self evident, this book, as does 

 no other upon the market, gives the reader 

 the most recent and most clearly expressed 

 information. The United States is taking a 

 lead in th? adoption of the KILN DRYING 

 method an 1 this volume will increase our 

 lead. It is a practical as well as a theoreti- 

 cal treatise. The text and illustrations guide 

 the way to the most efficient methods of 

 work. 



KILN DRYING improves the condition of 

 the wood for the purpose for which it is used; 

 it reduces losses from warping, checking, 

 case-hardening and honey-combing that occur 

 in Air Drying; it reduces the interest charge, 

 the Are risk, the weather attacks by reducing 

 the period necessary to carry wood from the 

 time it is cut to that when it is fit for use; 

 it reduces the weight and thus facilitates 

 handling and shipping. 



The present losses in preliminary Air Dry- 

 ing can be reduced by KILN DRYING from 

 12 per cent, for Hard Woods and 5 per cent, 

 for Soft Woods to 2 per cent. There is a 

 possible annual saving of $17,178,000.
