Experiments by Martiny and Peters are cited, the results of which 

 "in general coincide with our own except that in the second of the two 

 trials closer results were obtained as between the two methods than in 

 any of ours." 



Variations in fat of milk served to customers in dipping 

 FROM CANS, H. H. Wing, B. Agr., and C. D. Smith (pp. 68-71) —It 

 has been asserted that injustice is done to consumers by milkmen dip- 

 ping the milk from the top of the can or drawing it by a faucet at the 

 bottom, in that the cream rises to the top of the can and is given to the 

 customers served first, so that those who are served last get a milk with 

 little fat. To determine the variations in the percentage of fat in milk 

 served to different patrons along the route by dipping from the can, 

 milkmen were accompanied at three different times and samples of the 

 milk as it was about to be served taken for analysis, at least three dif- 

 ferent samples being taken from the same can at different times. The 

 milk was in each case the mixed milk of herds. 



It would seem from the duplicate gravimetric analyses that " where 

 milk is peddled by dipping from the can with an ordinary dipper, and 

 where no stirring is done except by the motion of the wagon and rais- 

 ing the dipper, substantial justice is done all the patrons so far as the 

 amount of fat apportioned to each is concerned. This conclusion seems 

 the more justified as each trial was made on a different milk route, and 

 represents the usual custom of three different milkmen, since each 

 man was cautioned at the beginning to in nowise depart from his or- 

 dinary practice."

Co OPERATIVE field TESTS DURING 1889, H. B. BATTLE, PH. D. 



(pp. 3-28). — A series of CO operative experiments similar to those made 

 by the station in 1888 was made on farms in fourteen different coun- 

 ties of the State, nine trials being with cotton and five with corn. In 

 general twenty-two twentieth-acre plats were used in each experiment, 

 acid phosphate, cotton-seed meal, and kainit being applied in different 

 quantities, singly on six plats, two by two on six plats, and all three 

 together in "complete fertilizers" on four plats, two plats being ferti- 

 lized with barn-yard manure or compost, one with " 2>^orth Carolina am-
