same number of pounds of light oats. From August 24th 

 to September 22nd the grades of oats were reversed so that 

 the horses which received the heavy grade during the first 

 thirty-day period received the Hght grade during the second 

 period. During both periods the horses were allowed to eat 

 what they wanted of an average quality of mixed hay. The 

 weights of the horses were taken twice a week on successive 

 mornings before watering to note any changes. The aver- 

 age of these two weighings is taken as the weight for that 

 particular week.
