 so that the results for the six cows may be averaged for eaeli period. 

 The following table shows the averages per animal during each of the 

 three periods. In calculating the net cost of food, corn meal was val- 

 ued at §24, wheat bran at 820, linseed meal at $20.50. hay at 815, green 

 vetch and oats at $2.75, and green soja beans at $4.40 per ton, and 80 per 

 cent of the value of the fertihzing ingredients of the food was deducted 

 from the first cost.

The analyses of milk show no considerable changes in composititm 

 which can be attributed to the intiuence of the diiierent rations. The 

 cows all slightly increased in weight during the experiment. The table 

 indicates only slight differein-es in the average milk yield in the dry 

 matter consumed, and cost of food per quart of milk in the several 

 periods. The results in general seem to be slightly better during the 

 first period, and are fiivorable to the green-fodder crops as compared 

 with rowen hay. They are similar to the results obtained in ])ievious 

 experiments with green vetch. Southern cowpeas, and serradella, and 

 lead the author to "recommend very highly the raising of any of the 

 stated new fodder crops, either alone or as mixed crops, for the purpose 

 of increasing the fodder resources of the farm during summer and autumn. 

 They may serve as green fodder as well as hay; most of them have a 

 higher nutritive ratio than either English hay, corn fodder, or corn 

 stover: they tend to im]>iove the soil chemically and idiysically; they 

 yield liberal returns, and are, as a rule, highly relished by cattle." 



Creamery record of the station for 1889 and 1890 (pp. 54-C9).— This is 

 a record for 1889 and 1800 of anumnts, kinds, and market values of the 

 feeding stufis fed. the fertilizing ingredients of the same, the average 

 composition of the milk, the cost of producing cream per quart and per 

 space, the amount received for the same from a cooperative creamery, 

 the calculated value of skim milk with whole milk at 3 cents per 

 quart, the analyses of cream and l»ntter fat, and the fertilizing constit- 

 uents of cream. The methods used at the station in the analysis of dairy 

 products are fully described. The feeding stuffs given consisted of the 

 ordinary grain feeds, hay, corn tVKlder, stover and silage, roots, and 

 numerous gieen fodders. The following statements are from the author's
