In either case, how-ever, the range involved is used from a number of central of using the camps in the same order every year, the ordercan be changed so that during a period of five or six years the rangeused from each camp will stand its share of grazing prior to seedmaturity, so far as is consistent with the use of the range when theforage is suitable for sheep. Such a plan is shown in figure 3. In a few cases the difficulty of adjustment has been overcome byusing three or four sheep allotments as the unit for a system ofdeferred ai*d rotation grazing, one allotment at a time being pro- Bui. 790, U.

The area to the right has been grazed during the maingrowing season. Much of the vegetation to the right is weeds and grasses of secondaryforage value. To the left the vegetation is mainly the best forage grasses of the region. Bui. 790, U. S. Dept. of Agriculture. PLATE XXX.
