FARM AND SCHOOL PROBLEMS. 



W In 1911 we shipped out of the United States, forest products 



to a total value of over $100,000,000. We consumed at home 23 

 billion cubic feet of wood.* 



FIGS. 1 and 2. Two Forestry Experts. 



PROBLEMS. 



1. The Bureau of Corporations of the Department of Commerce 

 and Labor has estimated that the existing supply of saw timber in the 

 United States is less than 3,000 billion board feet. What is this amount 

 equal to in cubic feet? 



2. At the present rate of shipment and home consumption how 

 many years will it take to consume the products of saw timber in the 

 United Stajes if we consume all of our product at home? 



We are already importing woods for certain purposes. We 

 are now annually consuming 5 million cords of wood for pulp. 

 Nearly half of this amount is imported. 



Since 1902 a systematic study of the strength and uses to 

 which woods may be put, has resulted in large economies in 

 consumption. 



* With an annual cut of about 23,000,000,000 cubic feet of standing 

 timber and a forest area of about 545,000,000 acres, the cut per acre is 

 42 cubic feet/ while the annual growth on the area has been estimated at 

 12 cubic feet per acre.
