ratiou." When corn took the place of part of tbe silage, tlie silage 

 forming an average of 44 per cent of the total fDod, tbe gross cost of 

 l)ork was about tbe same as wbere uo silage was fed. "Altbougb tbe 

 moisture in tbe silage ration was six times as mucb as in tbe grain ra- 

 tion, tbe animals drank witb it 7.9 pounds of water a day as average 

 for 100 pounds of pig (live weigbt) and 6.8 pounds of silage." 



Rations loitli and icWiout salt. — Two lots of pigs, eacb containing one 

 Cbesbire and one Duroc- Jersey, were fed from Marcb 20 to July 10 on 

 similar rations, except tbat one lot received a.small amount of salt eacb 

 day and tbe otber none. Tbe rations, consisting of grain and eitber 

 silage, prickly comfrey, or silage and comfrey togetber, were nearly tbe 

 same in amount for eacb lot, except tbat wben comfrej' was fed tbe lot 

 receiving salt consumed considerably more of tbe green food. Tbe re- 

 sults of tbe trial are stated in a table. " Tbe lot baving salt showed tbe 

 better gains under every ration, altbougb only under tbe grain ration did 

 tbey make a profitable growtb. Wbile under grain food only tbey drank 

 more water, but wbile baving a more succulent ration during warmer 

 weatber, they drank very mucb less than those without salt. While 

 prickly comfrey was fed the pigs without salt required 52.8 per cent 

 more water-free food for a pound of gain, tbe cost being 55.7 per cent 

 greater than witb salt, neither lot making a profitable growtb, how- 

 ever." 



Feeding pricMy comfrey. — During three weeks ))igs averaging about 

 64 pounds each in weight, were fed all the chopped comfrey they would 

 eat, receiving no otber food except about 5 ounces of corn meal each daily. 

 They refused to eat more than about 3 pounds of comfrey each per day, 

 and lost 0.9 to 1.6 j^ounds in live weight per animal each week of the 

 trial.

Cream raising by dilution, H. H. Wma, B. Agr., and C. D, 

 Smith (pp. 61-67). — These experiments were made to compare the 

 separation of the cream by two methods, one witb ordinary Oooley 

 creamer cans set in ice water, and tbe other by diluting the fresh milk 

 witb water of different temperatures and setting it in deep cans with- 

 out ice. The milk was in all cases mixed milk of the university herd, 

 consisting of about two thirds high grade Holstein and one third high 

 grade Jersey cows. The analyses were made by H. Snyder, assistant 

 chemist. 



Eleven comparative tests were made in which mixed milk from tbe 

 same milking was divided into two portions, one part being diluted 

 witb an equal weight of cold water (47 to 60° Fab.) and set in a Cooley 

 can in an open room having a temperature of 60 to GQ^, and the other 

 part set at once in ice water in tbe Cooley creamer, the time of setting 

 being the same in all the cases but two. Tbe milk taken was in some 

 cases freshly milked, in others "' had been carried on the milk route for
