42 REFORESTATION ON THE NATIONAL FORESTS. 



from 20 to 30 seed per spot, it cost per acre for Norway spruce $2.31, 



for yellow pine $4.69, and for Douglas fir $3.09. 



Method B : Complete broadcasting with no preparation of the ground. 



By sowing 100,000 seed to the acre the cost for Norway spruce 

 was $1.85, for yellow pine $12.95, and for Douglas fir $4.55. With 

 150,000 seed to the acre the cost for Norway spruce was $2.30, for 

 yellow pine $18.95, and for Douglas fir $6.35. With 200,000 seed to 

 the acre the cost for Norway spruce was $2.75, for yellow pine $24.95, 

 and for Douglas fir $8.15. With 250,000 seed to the acre the cost for 

 Norway spruce was $3.20, for yellow pine $30.95, and for Douglas 

 fir $9.95. 



An estimate is here given of the cost of sowing western white pine 

 and red pine by Method A on Class III site, and by Method B on 

 Class II site. The figures given are exclusive of the cost of the seed 

 and are based upon the same cost given in the preceding examples 

 for the same methods and sites. The cost of western white pine seed 

 is placed at $4.50 per pound and that of red pine at $9 per pound, 

 figures which are conservative for the calendar year 1910. If the 

 cost of sowing yellow pine, the most expensive of the three species 

 previously mentioned, is compared with that for sowing western 

 white pine and red pine, it will be seen that on an average it costs 

 approximately one-third more to broadcast the two last species than 

 the first, and a fraction over one-fifth more if the sowing is done 

 according to Method A in the Class III site. 



By sowing from 10 to 15 seed per spot in accordance with Method 



A, Class III site, it would cost per acre for western white pine $4.62 

 and for red pine $4.66. By the same method, but with from 20 to 30 

 seed per spot, it would cost per acre for western white pine $6.95 and 

 for red pine $7.04. 



By broadcasting 100,000 seed per acre in accordance with Method 



B, Class II site, it would cost for western white pine $16.82 and for 

 red pine $17.13. With 150,000 seed to the acre it would cost for 

 western white pine $24.87 and for red pine $25.32. With 200,000 

 seed to the acre it would. cost for western white pine $32.88 and for 

 red pine $33.51. With 250,000 seed to the acre it would cost for 

 Avestern white pine $40.94 and for red pine $41.70. The above esti- 

 mates are based upon the assumption that the area was traversed 

 only once. If it was traversed twice the cost would be increased 

 approximately 29 cents per acre.

An area, known as the Soleduck Burn, comprising 6,000 acres 

 within the Olympic National Forest, was burned over in the summer 

 of 1907 by a very severe fire, which destroyed the entire original
