would enable a person to turn over two crops of hogs to 

 one when the hogs were fed on milk alone." The Utah 

 station made seven experiments comparing grain and 

 milk rations with others of milk alone and grain alone, 

 embracing tests with grain in several combinations with 

 the milk. The grain used was equal parts of corn and 

 wheat, corn meal and wheat bran, wheat and bran, barley 

 and wheat bran, and also ground wheat alone. The grain 

 or meal used alone was made into a thin slop with water. 

 The experiments were conducted at different periods of 

 the year, mainly in summer and autumn. In addition 

 to the grain or milk rations, the hogs had plenty of 

 water, with access to charcoal and wood ashes ; they 

 were fed twice daily. A comparison of the various ra- 

 tions of skim milk alone, milk and grain together, 

 and grain alone is given in the following summary of 

 the Utah experiments :
