YELLOW POPLAR. 



The prospects for yellow poplar, shown in Table 5, are somewhat 

 better than for red oak. It grows a little more rapidly, gives a little greater 

 yield, and has a correspondingly lower reproduction cost. At 50 years 

 there is an estimated yield of 18,000 feet of timber averaging 12.8 inches 

 in diameter, costing $5.17 per thousand under Case 1, and $5.61 under 

 Case 2. Yellow poplar is such a highly useful wood that it will always be 

 needed by our varied industries. We can evidently obtain the smaller sizes 

 at a cost which is not excessive. If we want big trees we must pay a high 

 price for them.

DOUGLAS FIR. 



From every viewpoint, Douglas fir is one of the most interesting 

 species. There is more of it now standing than of any other timber in the 

 United States. It grows rapidly in extremely heavy stands, and can be 

 protected cheaply. 



Table 6 gives estimates of the cost of growing Douglas fir in the 

 region of its best development ; that is, in western Washington and Oregon. 

 The first cut is placed at 40 years, with an average diameter of 10.6 inches, 

 and a yield of 24,000 feet per" acre. This makes the cost of production $2.47 

 per thousand in Case 1, and $2.76 in Case 2. At 70 years, with timber 

 averaging 18.4 inches in diameter and ranging from 14 inches to 28 inches, 

 the yield is 50,000 feet per acre, making the cost $4.50 per thousand in 

 Case 1, and $4.56 in Case 2. At 100 years, with timber averaging more
