DESCRIPTIONS OF PLANTING SITES NOTED IN TABLES. 



1. Planted on block E under dense, tall oak brush with a generally unbroken 

 canopy about 5 feet above ground. ISTorth exposure, slope 25 per cent, elevation 

 7,200 feet. Soil silt loam to clay loam. Most of survivors under local breaks in 

 the canopy. 



2. On block E, immediately up hill to the south from the preceding planta- 

 tions. Similar site in all respects except that the oak brush is about knee high 

 and patchy. 



3. On block Q, moderately dense oak brush on a north exposure, slope 40 per 

 cent, 7,400 feet elevation, soil composed of 3 to 4 inches of humus over light 

 brown clay loam, clay and gravelly or stony clay (limestone). The stock used 

 in the first of the 1919 plantations listed is from Salmon National Forest seed, 

 the second from Sevier National Forest. Owing to excessive rabbit damage 

 these plantations were torn out at the end of the first year and replanted in the 

 spring of 1920 inside a rabbit-proof (poultry wire) enclosure. 



4. Planted on block Q, upon an area covered with oak brush of good develop- 

 ment forming an uneven canopy 4 to 5 feet above the ground. Aspect west, 

 slope about 15 per cent, soil much the same as on northern aspect preceding. 

 The first four plantations listed are tests of classes of stock, the fifth is a check 

 upon the results of the preceding year with 2-1 stock. The sixth and seventh 

 are fall plantations. On the first, each tree was protected by a conical pile of 

 oak brush built over it to protect it from the weight of snow, and hence snow- 

 fungus damage. It was ineffective. The last is a plantation upon a portion of 

 this site from which the oak was cut and the sprouts removed as they came up. 



5. Planted near block Q on a west slope under moderate to excellent oak 

 brush cover by common laborers. It is a portion of a large plantation set aside 

 for intensive observation. 



6. Planted on block 1 on a gentle west slope at 6,800 feet elevation. Site 

 covered by clumps of oak; plantation was evenly spaced, and some of the trees 

 were placed under oak shade and some in the open. Soil compact light yellowish 

 clay loam, overgrazed and eroded to a certain extent. Used as a site for testing 

 the age classes of stock. 



7. Planted on block 2, a north, aspect with 35 per cent slope, at '6,800 feet 

 elevation in the tension zone between the pifion-juniper and brush types. Area 

 is covered with scattered growth of mountain mahogany, bitter brush, pinon 

 and juniper. 



8. Planted near block Q, 7,400 feet elevation upon a south aspect, slight slope, 

 a severe site as indicated by the presence of cactus among the sagebrush and oak 

 clumps that cover the area. Soil is a dark compact, gray-brown silty clay loam, 

 underlain by clay. 



9. Planted next to block A in mixed sage and oak brush cover adjoining 

 aspen. Elevation 7,600 feet, exposure to west, slight slope. The soil is a 

 light-brown loam grading into clay loam, ground cover scant. 



10. Planted on block Q, 7,400 feet elevation on a flat covered with dense 

 sagebrush 2 to 3 feet tali. Part of the area cleared in the spring of 1917. 

 Soil is colluvial wash from slopes; on the surface, a dark grayish-brown com- 

 pact, silty clay loam succeeded by a light-brown compact clay to the depth of 

 15 to 20 inches, beneath which lies a stiff yellowish waxy calcareous clay. 



11. Planted on block Q, 7,400 feet elevation upon a ridge, top and brow of 

 ridge having a south exposure, covered with a low growth of manzanita 1 to 2 

 feet tall, interspersed with many openings. The soil is a yellow-gray and brownish 

 very fine sandy loam overlying a grayish-pink moderately compact clay. Soil 

 shallow, practically no humus. 



12. Planted on block Q on south slope immediately below preceding. The 

 ground cover here consists of isolated bushes of mountain mahogany and wild 

 apple with many barren openings between the bushes. The soil is similar to the 

 manzanita site above, but it tends to be deeper owing to colluvial accumulation.
