The condition of the grama-erass range of Pasture 2 is now about 
normal. In this case about 21 acres per head, yearlings and above, 
will furnish 365 animal-days’ feed over a period of years, provided 
the range is not stocked heavier than approximately one animal to 
40 acres during July, August, September, and October. During 
the remainder of the year enough additional stock can be grazed 
to make up for the reduction during the growing season. 
This conclusion is substantiated somewhat by the records for 
Pasture 5 (fig. 2). The grama-grass range of Pasture 5 actually 
furnished 365 animal-days’ feed per 20.4 acres during the year from 
May 1, 1915, to April 30, 1916, though the heaviest grazing was 
during late summer and fall, when it should be light. Study of the 
vegetation on this pasture shows that the condition of the range is 
only approximately 75 per cent as good as similar range in Pasture 
2. This and the fact that there was a shortage of feed in Pasture 
5 led to a decision that the pasture was 25 per cent overstocked 
during 1916. With a reduction of 25 per cent in the total grazing 
during the year, and light stocking during the growing season, it 
is estimated that the forage production can be increased 25 per 
cent in three to four years. The area will then carry stock at the 
rate of 365 animal-days’ feed annually on from 20 to 21 acres of 
the grama-grass area. If heavy grazing during the growing season 
is continued, the carrying capacity will, without doubt, be further 
reduced. 
These two pastures are typical of large areas of plains range where 
the grama grasses predominate. For such range in good condition,
