Hearing depletion, two things must happen, either the wood-using 

 industries will have to secure their supplies from other States, or 

 shut down and move to other localities."

This report, prepared co-operatively by the U. S. Forest Ser- 

 vice and the State Board of Forestry, covers the use of lumber 

 which by machinery or some other process has undergone some 

 change in form from the rough material. The products of the 

 planing mill, such as siding, flooring and ceiling, were not included 

 in the totals of material used. 



As a lumber producer Wisconsin now ranks fifth, having fallen 

 from first place in 1900 and 1904. The total annual production 

 of lumber is over 1,600 million board feet. The wood-using in- 

 dustries of the state use 930 million feet of lumber valued at $20,- 

 000,000. Very nearly half (49 per cent.) of this material was 

 imported. A large proportion was supplied by the Rocky Moun- 

 tain and Pacific Coast states, though freight rates permit the 

 manufacturers to draw their supplies from all parts of the country 

 and ship the finished products into the same sections from which 

 the material was obtained. 



Twenty-two different wood-using industries are represented in 

 the state. Forty different woods are used, of which nineteen are 

 local. Basswood is employed in twenty of the twenty-two in- 

 dustries. Seventeen use white pine ; sixteen, ash and elm ; fifteen, 

 maple ; and fourteen birch and oak. It is interesting to note that 

 100 M. feet of willow lumber worth $9.70 per M. was used in the 

 manufacture of woodenware. 



Inspections made in the various factories show a waste of from 

 5 to 35 per cent — average at least 20 per cent — of the total volume 

 of lumber consumed. The introduction of box factories as ad- 

 juncts to sawmills has materially decreased the waste of lumber 

 at many mills. One prominent concern operates profitably a 

 chemical plant in connection with its sawmill. The small and 

 defective hardwoods, together with the tops of felled trees on 

 the logged-off lands are utilized. The removal of the slash tends
