In Table No. 8 are given the cost in man and horse hours of 
labor for manuring alfalfa. These costs are reported in man and 
horse hours on the assumption that the amount of man and horse 
labor can be directly compared on the College and privately owned 
farms, while the value of that labor may vary widely between the 
College and privately owned farms, and may vary widely between 
privately owned farms in the same and different sections.
