ern wheat-grass, slender wheat-grass, meadow fescue, tall fescue, 
ved fescue, redtop, orchard grass, Canadian bluegrass, and alfaifa, 
both singly and in various mixtures. A few species have given good — 
results in pure stands, though the best results have come from certain 
mixtures. The value of the different species is discussed in the fol- 
lowing pages.? 
BRO ME-GRASS. 
Brome-grass (Bromus inermis) has been used with good success, 
whether planted alone or in mixture with-other species. This grass 
is well adapted to the climatic conditions of the Northwest, and on 
Fic. i.—A canal bank, showing western wheat-grass in the foreground and brome-grass 
and western wheat-grass in the middle of the picture. 
account of its habits of growth it is well adapted to the particular 
purpose of soil binding. The initial growth is fairly rapid, so that 
the grass gets well established the first season. It endures drought 
well and is quite resistant to alkali. 
The growth of brome-grass is unhindered where the alkali is of the medium 
grade (0.5 per cent). In fact, this grass can make excellent growth and seed 
production where the alkali is medium strong (0.7 per cent), and it has been 
observed to ripen some seed in the presence of very strong alkali (1.5 per cent) .* 
1Jt should be understood, however, that the results here reperted apply only to the con- 
ditions under which the experiments were made and do not necessarily indicate that the 
same species would behave similarly in other parts of the country.
