APPENDIX 55 



bark. The third plantation is on a gentle slope with northeast exposure. The 

 soil is less rocky, a clay loam. There are no shrubby associates of the scrubby 

 aspen, the scanty ground cover being composed of grasses and herbs. 



85. Planted on a moderate slope with northeast aspect in permanent brush 

 type composed of many species such as serviceberry, ninebark, rose, myrtlebrush. 

 The soil is a shallow loam, with a heavier subsoil near the surface. Altitude is 

 6,200 feet. 



86. Planted near the preceding in aspen cover of moderate density. The 

 exposure here is north, the slope moderate, and the soil is a sandy loam. 



87. Planted on a flat in an irregular stand of aspen interspersed with sage 

 openings. The soil is a sandy loam. 



88. These four plantations are adjacent, two on a flat above the brow of a 

 hill, two on the slope below. The entire area is covered with an open stand of 

 aspen, interspersed with young lodgepole pine and Douglas fir. The aspen is 

 more dense and uniform on the slope than on the flat. The ground cover on the 

 slope is pine grass; on the flat there is considerable Symphoricar-pos . Burrowing 

 rodents have done much damage, especially on the flat bench. The first planta- 

 tion listed on each site was planted by the center-hole method, the second being 

 by the slit method. 



89. Planted on a spruce fiat burned over in 1910 on the south side of Darby 

 Canyon at 6,600 feet elevation. There is a heavy sod on the area. The soil is 

 a sandy loam. 



90. Planted in the bottom of a ravine entering Darby Canyon from the south 

 at an elevation of 6,600 feet. The slope is gentle and aspect west. The soil is a 

 rocky clay loam. The ground is covered with a moderate herbaceous and grass 

 cover heavily grazed in summer. This area has been logged but not burned. 



91. Planted in the lower aspen on the west exposure south of the mouth of 

 Darby Canyon. The aspen is dense and there is a dense cover of pine grass 

 sod on the ground. The soil is a sandy loam. The slit method of planting was 

 used. Altitude is 6,600 feet. 



92. This plantation is in a mixed brush type of willow, ninebark, snowbrush 

 and rose, mixed with various herbaceous species on an old burn in Darby Canyon. 

 The slope is moderately steep. The exposure north. The altitude is 6,850 feet. 

 The soil is a very rocky clay loam. 



93. Planted on block L, in the middle of the natural blue spruce range at 7,800 

 feet elevation on a well-watered flat with a slight north exposure. Natural 

 blue spruce exists upon the area. The soil is a heavy clay loam, wet in spring 

 and likely to bake in summer. The plantation has been partly destroyed by a 

 small flood and by the digging of a pipe line trench through the area. 



94. Planted on block J at an elevation of 8,900 feet, above the natural limit 

 of blue spruce, along a small intermittent mountain torrent, exposure northeast, 

 slope 40 per cent. The ground is covered in the summer with a dense growth 

 of elderberry and niggerhead (Rudbeckia occidentalis), and in winter is subject 

 to snowslides. The soil is a brown clay loam underlain by brownish or grayish 

 clay. The surface layer consists of only partly decomposed vegetable material 

 brought down by snowslides. 



95. Planted in aspen of average density on a north exposure, moderate slope, 

 immediately adjacent to the Cottonwood Nursery. Plants placed in favorable 

 spots fairly free from competition. 



96. There is little description of this site in the records. 



97. These two plots are located on the slope and on the flat at the foot of the 

 slope, respectively, and adjacent. The general site is on the south side of the 

 canyon in an old Douglas fir burn, grown up to brush, willow, ninebark, rose and 

 snowbrush mainly. The flat has a moderate sod, while the slope bears only a 

 scattering of herbs among the brush. 



98. Planted in thin aspen adjacent to a sage flat. The cover is light, ground 

 cover scant grass and herbs, the slope very slight, with an easterly exposure. 



99. Planted in a large sagebrush flat burned over the previous year, and 

 bearing a dense cover of geranium. The site is almost flat, the soil a rather 

 compact silty loam. 



100. These plots are adjacent, one set on a northwest exposure, the other upon 

 a near-by flat bench. The first planting on each site is by the center-hole method, 

 the second by the slit method. The soil is a brown loam, well suited to the latter 

 method. The area is covered with small aspen, intermixed with some lodgepole 

 pine and Douglas fir. There is a fair ground cover of pine grass and herbs. 

 Ground squirrels and gophers did much damage.
