taken that all conditions of cows, feed, care and housing, 

 were equally good. With all these factors fairly balanced, 

 astonishing results were secured. 



Results of This Demonstration. 



Doubling the production of the best dairy farms in a 

 steady six-year run of practical and economical dairying is 

 obviously worth doing. It should challenge the best thought 

 and highest ambition in the dairy field. The balance of 

 right crops, right cows, right feed and care of the cows 

 spells outstanding and economical success in plain, practical 

 farm dairying, without introducing any extraordinary ele- 

 ment unless it be giving the right place to alfalfa. 



Yield Per Man. 



The area chosen for the Milk Per Acre demonstration 

 at the University of Illinois was surveyed and the 20 acres 

 enclosed by a fence built exactly on the line. An additional 

 acre was occupied by the buildings, yards, and garden, one- 

 third of this acre being used for the barn and cow yard. So 

 201/3 acres were devoted to the production of milk. 



This was the poorest piece of land on the University 

 farm, selected because it was similar to much of the soil 

 on which dairy farming is conducted. It was somewhat 

 rolling and had been continuously cropped for many years. 

 About three-fourths of the area was brown silt loam; one- 

 eighth, gray silt loam on tight clay; and the remaining por- 

 tion gravelly loam. 



Enough manure was produced by the cows to apply 10 

 to 12 tons per acre on the corn land each year and this was 

 the only manure used. The summer manure was hauled out 

 in the fall, and the land thus covered plowed and the re- 

 mainder of the corn land was manured and plowed the 

 following spring. 



The land was disced and harrowed to prepare a good 

 seed bed and planted to corn about May 10th, drilling the 

 corn one kernel every nine inches in the row. The land 

 was then harrowed and after the corn was up it was culti-
