drawn from the cow, not allowed to stand for a single 

 minute. The amount of cream was measured in the 

 mornincr after the milk had stood in the tube between 

 fourteen and fifteen hours. The tube stood in the milk- 

 room at the usual temperature for setting milk in win- 

 ter. The cow had been fed as usual that day, and for 

 days before — say about two quarts of mixed bran and 

 feed per day, on cut hay, with a little oat-straw. I may 

 add that this heifer had been milked on the morninof of 

 the day of trial as usual. I know of no reason why this 

 experiment is not in all respects a iair one. 



'' ' The mother of this heifer was tested in the first 

 davs of November, 1866, immediately after havinof been 

 purchased, and yielded i quart of cream from 3 J quarts 

 of milk, fed onlv on orass, and short at that. The 

 average yield of my Jerseys, tested by the tube yester- 

 day (Januar}' 29), was 20'45 P^^ cent, of cream, after 

 standinor less than fifteen hours.' '•' 



" The age at which Jersey cows should calve seems by 

 common consent to be fixed at two years. If allowed to 

 ofo much longer, thev seem to lose somethinor of their 

 natural tendency to lactation. The precocity of the 

 breed, however, is so great that, unless care is taken, 

 they sometimes come in much earlier. Mr. Mackie 

 writes, under date June 3, 1870, 'My yearling "Hebe 

 4th," out of ''Hebe ist," by "Cliff," dropped a calf last 



* The heifer in question gave 2%. quarts per day at the time her milk was tested. 

 The herd gave four quarts on an average. Of course, the proportion of cream was 

 very laige, as the herd was drying off.
