DIRECT SEEDING. 41 



By this method it cost per acre for Norway spruce $3.75, for yel- 

 low pine $13.03, and for Douglas fir $5.79. 



Method D : Harrowing in strips 8 feet apart twice before and once after sowing. 

 Eight seed sown per square foot. 



By this method it cost per acre for Norway spruce $2.92, for yellow 

 pine $12.20, and for Douglas fir $4.96. 



Method E : Complete broadcasting without any preparation of the ground ; area 

 traversed once. 



By sowing 100,000 seed to the acre, the cost (per acre) for Norway 

 spruce was $1.52, for yellow pine $12.62, and for Douglas fir $4.22. 

 With 150,000 seed to the acre, the cost for Norway spruce was $1.97, 

 for yellow pine $18.62, and for Douglas fir $6.02. With 200,000 seed 

 to the acre, the cost (per acre) for Norway spruce was $2.42, for yel- 

 low pine $24.62, and for Douglas fir $7.82. With 250,000 seed per 

 acre, the cost for Norway spruce was $2.87, for yellow pine $30.62, 

 and for Douglas fir $9.62. If the area had been traversed twice in- 

 stead of once, the cost in each instance would have increased approxi- 

 mately 16 cents an acre. 



CLASS II SITE. 



Method A: Seed spots 12 inches in diameter, spaced 9 by 9 feet; the soil 

 stirred to a depth of from 1 to 2 inches ; seed covered. 



With from 10 to 15 seed per spot, the cost per acre for Norway 

 spruce was $1.86. for yellow pine $2.55, and Douglas fir $2. With 

 from 20 to 30 seed per spot, the cost per acre for Norway spruce was 

 $1.93, for yellow pine $3.31, and for Douglas fir $2.21. 



Method B : Broadcasting over entire area with no preparation of the soil ; area 

 traversed only once. 



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

 $1.65, for yellow pine $12.75, and for Douglas fir $4.35. With 

 150,000 seed to the acre, the cost for Norway spruce was $2.10, for 

 yellow pine $18.75, and for Douglas fir $6.15. With 200,000 seed 

 to the acre, the cost for Norway spruce was $2.55, for yellow pine 

 $24.75, and for Douglas fir $7.95. With 250,000 seed to the acre, 

 the cost for Norway spruce was $3, for yellow pine $30.75, and for 

 Douglas fir $9.75. If the area had been traversed twice instead of 

 once, the cost in each instance would have been increased approxi- 

 mately 29 cents per acre. 



CLASS III SITE. 



Method A: Seed spots 12 inches in diameter, spaced 6 by 6 feet; ground loos- 

 ened from 3 to 4 inches in depth ; seed covered ; soil not tamped. 



With from 10 to 15 seed per spot, it cost per acre for Norway 

 spruce $2.20, for yellow pine $3.89, and for Douglas fir $2.59. With
