Unfortunately the growth of these colts was somewhat irregu- 

 lar, so that the results do not allow as definite conclusions as 

 would otherwise be the case. It is especially noticeable that in 

 the third period animal No. 1 made a very small growth, a fact 

 which is due to some cause that is not evident. But notwith- 

 standing this irregularity of increase in weight, the outcome of 

 the experiment is such as to show no superiority for the oats as 

 food for producing growth merely. In fact, if anything is 

 indicated it is that the advantage was with the mixture of peas 

 and middlings. A gradual decrease in the average daily growth 

 in passing from one period to another, may be fairly charged to 

 the increase in the weight of the animal without a corresponding 

 increase of the amount of food. Granting that the ration of 

 mixed grains was not inferior, at least, to the ration of oats for 

 producing growth, the important question then becomes that of 

 the relative cost of the two rations. Of course the peas were a 

 costly food and were used in the case of this experiment merely 

 because they constituted a nitrogenous food which is a perfectly 

 safe one for horses. It is fair to assume that gluten meal would 

 have answered the purpose equally well. Now a mixture of 

 gluten meal and wheat middlings, if in the same proportion and 

 quantity as were the peas and middlings in the first period, would 

 cost about eleven cents a day,. whereas an equal weight of oats 

 would cost about sixteen cents a day, basing our estimates of
