The extension of the dry-farming area in Utah and the bringing of many thousands of acres of virgin land under wheat cultivation, in large farms, has, in recent years, caused much improvement in the use of farm machinery. One great improvement has been the adoption of the Combined Harvester, which cuts, threshes and sacks the grain in one operation in the field at a minimum of cost. This has been an important factor in the success of the dry-farming movement.
