many instances there will be a loss also in efficiency or satisfactory 

 service. 



Lumber and planing-mill products constitute that portion of the 

 industry of lumber manufacture exclusive of logging, which takes place 

 within the state. Logging as an industry in Illinois is relatively insignifi- 

 cant, constituting an enterprise equivalent to less than }i of 1 per cent of 

 the total manufacturing industries. But the planing-mill industry is of 

 greater importance, handling in 1909 12.53 per cent of all lumber con- 

 sumed within the state, and having closest contact with the building in- 

 dustries and the use of finished lumber for the construction of buildings 

 in cities and on farms, which, with other uses of lumber outside of manu- 

 factures, absorb nearly 40 per cent of all lumber consumed in the state. 



The manufacture of wooden furniture as an industry must cease 

 to exist with the substitution of metal for wood. This industry will be 

 one of the last to abandon the use of wood altogether, since the prefer- 

 ence for wood remains strong enough to permit high prices to be paid 

 for woods of high quality, such as walnut. 



Holding chief place among these in point of demand for wood and 

 its place in industry, is the construction and repair of steam and electric 

 raihcay cars, which, while listed under manufactures, is one of the chief 

 uses of wood in the transportation industry. Car-making uses for new 

 cars alone 28.42 per cent of all lumber used in manufacturing, and em- 

 ploys 7.7 per cent of all the factory employes. 



Although the use of steel in car construction is increasing, yet out 

 of 158,022 cars of all types made in 1919 in the United States, 6G.15 per 

 cent were built with a wooden superstructure on a steel frame, 2.68 per 

 cent were all of wood, and 2.61 per cent had wooden interior finish or 

 linings, making a total of 71.44 per cent of new car construction all or 

 in part of wood. 



Agricultural implements and machinery rank next as large con- 

 sumers of wood, taking 5.74 per cent of all lumber used in manufacture. 

 In this industry, more and more of the parts formerly made of wood 

 are being replaced by metal, and it is difficult to predict how far the 

 substitution will go. The same is true of wagons and vehicles, requiring 

 2.00 per cent, and to a certain extent of others of the industries shown 

 in tabulation B; but substitution becomes an urgent question first in 

 the great industries which require large and dependable supplies and 

 can not exist on the precarious output of second growth or cut-over 

 areas.
