1. Cotton-seed meal with a minimum percentage of oil 

 did not alter the percentage composition of the milk. 



2. The addition of one-half to thi'ee-fourths of a pound 

 of cotton-seed oil to the cotton-seed meal appeared to in- 

 crease the fat percentage in the milk about .4 of 1 per cent. 

 (5 to 5.4), and this increase was maintained during the six 

 weeks of the feeding period. 



3. The substitution of Cleveland flax meal for the cotton- 

 seed meal and oil resulted in a decrease of the butter fat to 

 about the percentage found in the tirst period, while tlie 

 nitrogen percentage was increased. This change in com- 

 position was probably due to the removal of the cotton-seed 

 oil from the ration, and not to the influence of the flax meal. 



4. Cotton-seed meal with mininmm oil caused no marked 

 variation in the chemical composition of the butter fat. 



5. The addition of cotton-seed oil to the cotton-seed meal 

 ration produced a noticeable increase in the melting point 

 and iodine number of butter fat. 



(). Cotton-seed meal with a minimum oil produced a firm 

 butter. 



7. The addition of cotton-seed oil, while it increased the 

 melting point of the ])utter fat, produced a softer, more 

 yielding butter than that produced by either the cotton- 

 seed meal or the standard ration. 



8. An excess of cotton-seed oil in the ration is likely to 

 afiect the health of the animal. 



Close attention was paid to the composition of concen- 

 trated feeds, and the farmers were warned of the following 

 adulterations : cotton-seed meal mixed with fine ground hulls 

 for genuine meal ; finely gi'ound corn-cobs for middlings in 

 mixed feeds ; finely ground rice hulls in the adulteration of 

 standard grains ; and oat ottal instead of ground oats in 

 mixing the so-called provender or cracked corn and ground 

 oats. 



In experiments with green crops, wheat and winter vetch 

 were found preferable to winter rye for early forage ; the 

 chief value of barnyard millet was found to lie in its use as 

 green fodder, by successive seedings using it until Septem- 

 ber. It was found to be not suitable for hay and taking the
