FOREST SERVICE. 427 



study and compile data on sawmill, logging, and miscellaneous 

 wood-working machinery and on pulp grinders, barkers, machinery 

 for shredding and hogging wood, and chippers; and will design 

 experimental types of open-tank and pressure-treating plants for 

 the treatment of posts, poles, ties, paving blocks, piling, etc. 



Wood-utilization projects will include a study in cooperation 

 with four manufacturers of the suitability for pencil manufacture of 

 the following Westein woods: Rocky Mountain red cedar, alligator 

 juniper, Western juniper, redwood, mcense cedar. Western red cedar, 

 Port Orford cedar, Alaska C3^press, and mountain cedar; a study of 

 the suitability for shuttle manufacture of yellow cedar. Pacific yew, 

 chinquapin, cascara sagrada, madroiia, Pacific dogwood, and moun- 

 tain mahogany; and studies of the suitability of short lengths of 

 cypress for tobacco boxes and butter tubs, and the suitability of 

 incense cedar for the manufacture of cigar boxes. A field study 

 will be made of the manufacture of hickory products, and statistics 

 of wood consumption will be obtained in Louisiana, Michigan, 

 ]\Iissouri, and Penns3dvania. All of the various forest regions in 

 the United States will then have been covered and information will 

 be available on the uses of all the domestic and many foreign woods. 



Statistics of prices will continue to be collected quarterly, both at 

 the mills and in the wholesale distributing markets. There will 

 also be made studies of substitution, which will include investigation 

 of the substitution of fiber packages for wooden boxes, to learn the 

 extent to which the substitution has gone and the character of the 

 raw material going into the fiber packages, whether mill waste or 

 material that should go into high-grade lumber; substitution of such 

 materials as cement, concrete, tile, and prepared roofings for woods 

 in general construction, instead of sheathing, siding, flooring, fencing, 

 shingles, fence posts, etc. ; substitution by the railroads in the manu- 

 facture of steel freight cars, passenger cars, and sleeping cars and in 

 the use of concrete for trestles and bridges, stations, and platforms; 

 and substitution in the furniture industry, as evidenced by the 

 manufacture of metal filing and office cabinets, tables, show cases, 

 ice boxes, and numerous other kinds of cheap and medium grades of 

 furniture. The vehicle and implement industry is still another field 

 where iron, steel, and aluminum are playing a large part in substitu- 

 tion. For each of these industries separate inquiries will seek 

 authentic information of the present and probable future effect of 

 substitution upon the demand for wood.
