1030 JOURNAL OF FORESTRY 



Present and Possible Products from Canadian Woods. By J. S. 

 Bates. 1917. Pp. 16. 



This is a paper read before the Canadian Society of Civil Engineers 

 by the Superintendent of the Forest Products Laboratories — a rapid 

 survey of the subject of utilization of wood and its derivatives. 



The discussion is based on a chart which enumerates the various uses,

 it in full. The italicized items are materials now manufactured in 

 Canada.
