Experiments with method.s or setting and churning milk, 

 Isaac Ross (pp. 3-(>). — These were with the milk from three Jersey 

 cows for six weeks. Six diflferent methods of setting milk were used, 

 each for one week. The record as given shows that in this case the 

 best results as regards amount and quality of butter were obtained 

 when the milk Avas set twenty-four hours in well-water, changed 

 twice daily. Apparently, however, no allowance was made for dif- 

 ferences in the feeding and treatment of the cows, nor for the nat- 

 ural variations in milk and butter yield. 



Experiment in setting milk verst'S creaming with the De 

 Laval separator, J. AT. Hart (pp. 7, 8). — Tests were made for six 

 days with the milk of eleven Jersey cows to compare the two methods. 

 Circumstances stated in the bulletin made the tests inconclusive. In 

 this case, however, as in other experiments in the South, the indica- 

 tions vv^ere that for that region the centrifugal is more economical 

 than the deep-setting system of creaming milk, because of the great 

 expense attending the use of ice. 



Experiments with varieties of vegetables, James Clayton (pp. 

 9-16). — Notes are given on tests of forty-six varieties of tomatoes, 

 twenty of potatoes, fifty-three of bush beans, and forty of English 

 peas. Among the varieties of tomatoes. Acme, Golden Queen, and 

 Paragon are named as A-ery desirable. Of potatoes, Burbank, Mam- 

 moth Prolific, and Pose's Xew Giant, are specially recommended.

 contains brief statements regarding composition, formation, and 

 deterioration of soils; composition of plants and commercial fer-

 of cotton seed as a fertilizer; commercial Aalues of fertilizers for 

 1889; methods of mixing fertilizers; and the provisions of the Ala-

The manufacturer who sells his goods in Alabama is required by law to brand 

 on each bag or package his guaranteed analj'sis of the fertilizer contained 

 therein. To protect the farmer against fraud, an official chemist has been pro- 

 vided by the State whose duty it is to furnish the commissioner of agriculture
