 every case is stated in round numbers, and is estimated at the point of 

 production.

Fig. 3.— Forest products in 1907. 



Nearly three-fifths of the total value of our forest products is made 

 up of lumber, shingles, and lath, and a little less than one-fifth of fire- 

 wood. No other group of products contributes as much as 10 per 

 cent of the total value. 



The quantity of forest material required for these products under 

 present conditions of logging and manufacturing is shown graphically 

 in figure 3. The total exceeds 20 billion cubic feet. Of this, lumber 

 and shingles take a little more than two-fifths; firewood, one-third; 

 posts, poles, and rails, about one-twelfth; and hewed cross-ties, about 

 one-sixteenth; relatively small quantities are required for the other 

 products.
