ENGINEERING ON THE FARM 



lumber grading which would include all the terms used 

 and their meaning would require a small volume, and such 



knowledge is necessary only 

 to the expert lumberman. 

 For farm purposes lumber 

 is usually bought at a local 

 yard which will have in 

 stock the kinds of lumber 

 that can be most readily 

 secured at the least cost and 

 will answer the requirements 

 of that locality. The follow- 

 ing are standard grades of 

 white pine, Norway pine, 

 spruce, and tamarack, for 

 which there is the most call 

 at the smaller lumber yards 

 and which are carried in 

 stock :

No. 3, No. 4, and No. 5 Mixed Widths 



These may be had rough, surfaced on one side, or surfaced 

 on two sides. The No. 1 common boards can be used for 

 outside finish where it is to be painted. The general practice 

 is to order No. 4 boards and pick out the best for sheathing, 

 taking the poorest for first or rough floors. This cannot 

 always be done, as a great many of the country yards do 

 not handle grades lower than No. 2.
