cottonseed meal 2,601.8 lbs. of milk. With peanut meal at $40, velvet bean 

 meal at $32, and cottonseed meal at $50 a ton, milk was produced at IG, 1G.5, 

 and 16.6 cts. per gallon, respectively, when these concentrates were fed. 



Corn silage and sweet potato silage were fed by the reversal system to two 

 lots of seven cows each during four 16-day periods. In addition, the cows 

 were fed a ration of 2.5 lbs. of cottonseed meal and 7.5 lbs. of wheat bran. 

 Little variation occurred in the weight of the cows during the test. On corn 

 silage the cows gave 7,888.3 lbs. of milk at a cost of 11.8 cts. per gallon, while 

 on sweet potato silage they gave 7,598.4 lbs. of milk, at a cost of 14.2 cts. per 

 gallon. In thi^ test corn sUage was valued at $4 and sweet potato silage at 

 $13.33 per ton. 



Dairying- in Plorida, J. M. Scott {Florida Sta. Bui. 1^2 {1918), pp. 5D-76, 

 figs. 6). — The author discus.ses the need for increased dairy production in 

 Florida, especially on the average farm ; the factors affecting cost of milk 

 production ; the improvement of dairy herds by selection, the use of good sires, 

 and the raising of heifers from the best-producing cows ; the effects of feeding 

 stuffs on the color, odor, and composition of milk ; qualifications of a good 

 dairyman ; and cow-testing associations. 



The station herd is cited as an example of what may be accomplished in 

 improving dairy herds by selection and by the use of good sires. Ten years 

 ago the average annual milk production per cow of the 12 cows in this herd 

 was 2,600 lbs. During the past year the average of the 20 cows in this herd 

 was 4,440 lbs. The average total feed and labor cost of producing milk in the 

 station herd during the past year was 19 cts. a gallon. 



A study of share-rented dairy farms in Green County, Wis., and Kane 

 County, 111., E. A. Boeger {V. S. Dept. Agr. Bui. 603 {1918), pp. IJ,, fig. 1).— 

 The material for this study was obtained from 84 farm-management survey 

 records made in Green County, Wis., in cooperation with the Wisconsin Ex- 

 periment Station, and from 59 records made in Kane County, 111., all for the 

 crop year 1915, together with data from 147 survey records taken in the 

 Illinois region by the Illinois Station in 1912. 



With regard to rental terms, the landlord in the Illinois group generally 

 owned the cows and paid all the farm road tax, while in the Wisconsin group 

 he owned but half the cows and paid only part of the road tax. In the Wis- 

 consin group 76 per cent of the leases ran for one year, none being for more 

 than three years. In the Illinois group 63 per cent of the leases were for one 

 year, none being for more than five years. 



The average farm in the Wisconsin group had 140 acres tillable and 84 acres 

 in pasture and supported 25 cows. The Illinois farms averaged 139 acres 

 tillable and 58 acres in pasture and supported an average of 43 cows. The 

 Wisconsin cows produced an average of $70 worth of dairy products, and the 

 Illinois cows $94 worth per head annually. In the Wisconsin group both 

 landlord and tenant made least on farms selling milk fat, more on farms 

 marketing milk through the cheese factory, and most on farms selling milk to 

 condenseries. In the Illinois group none of the milk was made into cheese, 

 and the profits were about the same, both to landlord and tenant, whether 

 the milk was sold to the condensery or for market. The introduction of pure- 

 bred cows into the dairy herd in the Wisconsin group has been very profitable 

 both to landlord and tenant, but apparently only to the tenant in the Illinois 

 group. 



In both the Wisconsin and Illinois groups the tenant remained on the farm 

 longer under the yearly lease than he did where the lease was for a longer 

 period.
