 crease 360

Lumber for use in construction 375 



Residential construction may reach three 



million units annually by 2000 375 



Nonresidential construction closely related to 



economic growth 384 



Maintenance and repair construction requires 



substantial quantities of lumber 391 



Railroads' use of lumber consists chiefly of ties. 397 

 As farm output increases, more farm service 



structures will be needed 403

double by 2000 406

chiefly for household furniture 407 



Many other manufactured products require

Major shipping use is for wooden boxes, cases, 



and crates 413

 jections 421
