48 REFORESTATION ON THE NATIONAL FORESTS. 



The seed was sown broadcast, one-half on the snow and the other 

 half on bare ground, without in any way preparing the soil. The 

 weather at the time of sowing was clear, warm, and dry. Inspection 

 made July 17, 1909, showed an average of 43,000 Engelmann spruce 

 and 10,000 lodgepole pine seedlings per acre. A recent inspection 

 showed that the drought during the summer of 1910, combined with 

 winter killing, had killed a large number of the seedlings, but there 

 still remained per acre an average of 10,000 Engelmann spruce and 

 4,000 lodgepole pine. 



BLACK HILLS NATIONAL FOREST, SOUTH DAKOTA. 



On July 2, 1905, 38 pounds of yellow-pine seed, collected in 1903 

 on the Pecos National Forest, New Mexico, were broadcasted on bare 

 ground in the center of what is known as the Elk Creek burn of 

 1893. The area is on nearly level ground, sloping gently to the 

 south, and the soil is a shallow loam with schist outcropping. At the 

 time of the sowing there was a scanty ground cover and a scattering 

 growth of aepen. About 30 per cent of the area, however, was bare. 

 On October 30, 1909, an inspection showed an average of 24,700 

 seedlings per acre, all of which were making a good growth. 



SEQUOIA NATIONAL FOREST, CALIFORNIA. 



In November, 1909, a tract within the Sequoia National Forest, 

 known as the Shake Camp experimental area, situated in Tulare 

 County, in the west slope of the Sierra Nevadas, was sown to Doug- 

 las fir. The tract was near the top of a low ridge, with north and 

 east exposures, at an altitude of approximately 4,100 feet. The soil 

 was dark, sandy loam. An open stand of black oak (Quercus 

 emoryi) covered the area and the ground cover was of grass and 

 filaree. Sowing was done by the seed-spot method, the spots being 

 from 12 to 16 inches square, and spaced 8 by 8 feet. Each spot was 

 cleared and the soil stirred to a depth of from 4 to 6 inches. The 

 seed was covered one-half inch deep. Six pounds of seed were used 

 per acre, some of the seed being coated with red lead. An examina- 

 tion on May 29, 1910, showed that rodents had taken most of the 

 untreated seed. In that portion of the area sown with treated seed 

 the majority of the seed spots contained seedlings, some as many as 

 10, but with an average of 4 or 5. 



TRINITY NATIONAL FOREST, CALIFORNIA. 



An area on this Forest burned over many years ago, and since 

 then rather heavily grazed, was sown in December, 1909, and in 

 March, 1910. The tract has a hot southern exposure and an eleva-
