than the production of either of these crops to the exclusion of the 

 other. In the most western region of its development the growing 

 of durum wheat, emmer, millet, and alfalfa will probably constitute 

 the best crop adaptation for this type of soil under conditions of 

 scantier rainfall. 



FARM EQUIPMENT. 



The farm equipment upon the various areas where the Carring- 

 ton loam has been encountered varies considerably. In the more 

 eastern locations the regular equipment of the central prairie States 

 dominates with heavy two or four horse teams and an adequate 

 supply of power machinery. In many instances the farm buildings 

 include the dairy barn and silo. In Iowa this form of equipment 

 predominates, although stock raising for beef purposes is more preva- 

 lent than dairying as yet. In Minnesota and Xorth Dakota the farm 

 equipment is usually that of numerous teams and power machinery 

 for the seeding and harvesting of large acreages of spring wheat. 

 The barns for the housing of dairy cattle are not so numerous, 

 although dairying is gaining a foothold, particularly in Minnesota. 



The type is rather easily tilled and is not difficult to keep in good 

 condition, provided proper crop rotations are adopted. Light-weight 

 teams and equipment, however, are out of place in the cultivation of 

 this soil; and in the areas where it is developed as a prairie soil, 

 particularly, the four-horse hitch and power machinery are better 

 suited to the Carrington loam than any lighter equipment. 



SUMMARY. 



The Carrington loam is an extensive and important general farm- 

 ing soil. It is developed as a timbered soil in the region around the 

 southern end of Lake Michigan and as a prairie soil in Iowa, Min- 

 nesota, and North Dakota. 



The Carrington loam is one of the most extensive soil types derived 

 directly from glacial till to be found in the central prairie States. 



Both in its physical characteristics and in its organic matter con- 

 tent it is a soil well suited to the production of a wide range of gen- 

 eral farming crops. Chief among these are corn, oats, and grass, 

 which dominate the acreage in the more southern locations. Spring 

 wheat dominates the more northern areas where the Carrington loam 

 is found, while flax and barley are here subordinate crops. 



Irish potatoes are well suited to production upon this soil and 

 should constitute a commercial crop throughout a considerable por- 

 tion of the territory where it is found. 



Aside from the general farming interests developed on the Car- 

 rington loam there is a considerable production of beef cattle in the
