resources of this country. From this wood, by industrially developed 

 chemical methods, the entire output of naval stores, embracing 

 turpentine, rosin, tars, pitch, rosin spirits, and rosin oils, having an 

 annual value of at least $30,000,000, may be obtained without box- 

 ing or turpentining a single live tree. 



There is more than sufficient waste material to yield annually all 

 the papers (except news), paper and box board, and building board 

 required, for which wood is suitable. 



More methyl alcohol, acetate of lime, and acetone can be pro- 

 duced from this wood than is now made in the country, and large 

 quantities of ethyl alcohol may also be recovered. While it has not 

 been proved that these four products can be made profitably from 

 waste resinous wood, it is not at all improbable that the manufac- 

 ture of one or more of them, in conjunction with other products, 

 would be practicable. 



There are millions of acres of cut-over land covered with stumps 

 and dead and down timber, all of which, because of its resinous 

 nature, decays very slowly, enduring for years. There is enough of 

 such material to supply all demands for the above-mentioned prod- 

 ucts for a very long period. The processes, equipment, and technique 

 for the utilization of this material are either in operation or may be 

 readily devised. 



LOCATION, MANAGEMENT, AND OPERATION OF PLANT. 



The financial success of the production of wood turpentine and 

 other materials from waste wood is not controlled by the yield of 

 valuable products alone, but is also largely affected by the location 

 of the works with reference to transportation of raw material, and 

 the business ability and technical skill with which they are con- 

 ducted. As labor and transportation charges are the chief elements 

 in the cost of conducting these plants, they should be located as close 

 to the supply of raw material as possible, in order that the cost of 

 collecting and hauling the wood and disposing of the products may 

 be reduced to a minimum. It is well to give the most careful at- 

 tention to location; the plant should always command two inde- 

 pendent avenues of transportation for raw material and finished 

 products. Other things being equal, the cost of wood is least when 

 the works are located close to a sawmill, as in this case much of the 

 wood has already been collected for mill purposes, the wastes from 

 which are available at the smallest possible cost. Mill waste, how- 

 ever, is seldom as rich in turpentine as what is known as "lightwood," 

 so that if the mill is located at some distance from the lightwood 

 supply it may prove more profitable to locate the plant at the light- 

 wood supply and haul the mill waste. Each case must be decided 

 after careful consideration of all the circumstances, and therefore
