A recommended scree for replacing soils that 
are close textured and impervious, or too rich 
and moisture retentive, or to counteract inescap- 
able shade from remote trees or other objects, is 
mixed from equal parts of ordinary soil, coarse 
sand and fine gravel or rock chips, including 
some lime. This provides an excellent base for 
all Great Plains plants. The needs of certain 
subjects for portious of richer soil may be met by 
adding leafmold or other humus, locally, in 
planting or in top-dressing.
