BUILDING MAT E R I A L 



LUMB3R 



Before commencing to prepare a bill of lumber 

 for a building, the grade of lumber appropriate for specific 

 uses is the first thing to determine. 



Oregon mills grade according to certain establish- 

 ed standards; California mills grade finer and to somewhat 

 different standards. 



In term practicable of application an endeavor 

 ie made in the preparation of the following data to list 

 grades of various kinds of lumber of both Oregon and Cali- 

 fornia makes, Small local mills as a rule do not make any 

 pretense of grading beyond clear, and material that is not 

 clear. In purchasing from them, to secure proper material 

 is largely a matter of pick and choose.
