Practical conclusions of economic value (pp. 1<>7-1G9). — The above 

 experiments afforded an opportunity for comparing Atlas gluten meal 

 with corn meal and bran and with cotton-seed and linseed meal. The 

 results are summarized below : 



Comparisons of corn and bran, Atlas, and cotton- seed-linseed rations. 



1 One and one-sixth times the fat . 



"The Atlas ration was more economical than the corn and bran ration. More 

 milk was made thereon, and the food cost more; hence the milk was made but X per 

 cent and the butter but 6 per cent cheaper on the richer ration. Atlas gluten meal 

 at $16 is not much cheaper than corn and bran at $15 and $13, respectively. 



"Apparently the cotton-seed-linseed ration made more milk and butter than the 

 Atlas ration, and cost more. The periods, however, were of different lengths, and 

 the animals were fed some 3 and some 5 periods; hence the figures arc in reality 

 useful only as means to arrive at the cost of food per unit of production. In this 

 respect absolute equality is found. So far as can be judged under the somewhat 

 irregular conditions of tins test, the 2 rations were financially of equal value." 



The fertilizing value of the different rations is considered. 



Some observations on the relation bet-ween body conformation 

 and production in cows, E. A. Bogdanow (Jour. Landw., 45 {1S97), 

 JVo. 3-4, pp. 271-293, pi. 1). — The author made various measurements 

 on 80 cows of the herd at Tapiau, whose record for several years was 

 known. The method of measurement followed was that described by 

 Werner. 1 Various groups were formed according to the production of 

 milk, butter, etc., and the measurements of the cows in the different 

 groups were studied and compared. 



From the results the author concludes that a close relation between 

 external conformation and production is so apparent as to be unmis- 

 takable. Furthermore, so far as could be judged from special studies 

 of early and late maturing cows, it appeared that the best yields were 

 obtained from cows which matured relatively early. 



Experiments on the effect of different grain and concentrated 

 feeds on the milk production of cows, Ramm (Landw. Jahrb., 26 

 (1897), Xo. 1-5, pp. 693-731). — This experiment was with 2 lots of 5 

 cows each, and included trials of 18 different grain rations, each fed in 

 addition to a basal ration of If kg. of hay, 6 kg. of straw, and 50 kg. of
