tributed to accidental causes, and as the nature of the food was 

 the same, there being no radical change, one succulent food 

 being exchanged for another equally succulent, it cannot be said 

 that the digestive prgans were in any way overtaxed. Neither 

 was the food less palatable for it was perfectly preserved and 

 greedily eaten. There is no escape from the conclusion that 

 the Southern corn ensilage was less valuable in the feeding 

 barn as its analysis shows it to have been in the iaborator}* 

 The next step was to increase the grain ration by feeding 

 four pounds of mixed grain instead of i^. Looking at our 

 curved lines in Cut i ixom. period two to three it is found that in 

 four of the individual records a small shrinkage still manifests 

 itself. In five cases there is a small increase in product while 

 the total milk, Sec. 3, remai s almost constant, there being but 

 7-10 of a pound increase daily on the milk of the entire herd. 

 There is reason for believing that this ration, had it been fed 

 at the commencement of Period 2, would have kept up the flow 

 or at least would have come very near to it, but from the bot- 

 tom of Table A it is seen that t-he ration for the third period 

 cost fifteen cents daily for each cow while for Period i it cost 

 but 11^ cents. 



During the _/b?/rM/^r/<?^ a still further addition was made 

 of two pounds of ground buckwheat, increasing the cost of the 

 ration to seventeen cents per head daily. The effect of this 

 was to increase the daily yield of eight of the cows, as shown 

 by the upward direction of the lines in the cut, one. No. 15, re- 

 maining stationary, while the total milk increased 3^% 



Period five y^ -3.% \\V.^ four, except that six pounds of corn 

 fodder were fed in place of five pounds of bean vines, but as the 

 feeding value of the two is nearly identical this variation was 

 probably without effect. All of the cows, except No. 8, increas- 

 ed in quantity during this period, and by the indication of the 

 lines in the cut it appears that the increase was neaaly identical 

 with the previous period. 



Period sixth. A radical change was made in the grain fed, 

 gluten meal three pounds and corn and ccb meal two pounds 

 being used, the ensilage and dry fcdder remaining the same. 

 The result was a decided increase, the total yield coming up to 

 and slightly surpassing the yield at the commencement of the 

 work. This closes the work with Southern ensilage, and gives
