as may bo desired. The lines of moot promise, however, have been 

 its use in paper making and in the distillation of pine sawdust 

 for the production of turpentine. Much remains to be accomplished, 

 however, to make this work an unqualified success. 



Still another dissipation of timber wealth has occurred 

 through prejudice or the ignorance of the properties of certain 

 woods. Fr-r some reanon certain species have been considered as 

 inferior largely because such a prejudice has been formed against 

 them as to render then. 1 , practically valueless on the lumber mar- 

 kets on which account they were left in the wood?, a tot-&,l loss. 

 In many cases the popular conception of their value has later not 

 been borne out by the facts, or has been found to bo the result 

 of ignorance of the proper method of handling these species. 



ITo table examples are those of the hemlock and red gum 

 in the East, which for a long time wore considered worthless and 

 woro wasted, but which upon a better understanding of their use 

 and properties have come to have considerable value as lumber 

 trees. The western hemlock and tanbark oak suffered the same 

 fate, and caused the total Ions of millions of feet of good lum- 

 ber. To eliminate this waste timber testing laboratories are 

 conducted by the Forest Service in which woods are tested to as- 

 certain their true value and properties and to formulate methods 

 whereby they ms.y take their rightful place among the woods of 

 economic.-. 1 ,! value to man.
