While 102 heifers secured certificates under the 175 lbs. fat standard, 

 43 made 275 lbs. fat and over, and averaged 26.7 months old at the 

 time of calving, and in their nine months' test period, yielded 6,032 lbs. 

 milk; test, 5.21; fat, 314.5 lbs.; and 15A lbs. milk on the last day of 

 the nine months. When the fat is taken at Is. per lb., the return is 

 equal to £15 14s. 6d. per head, which would be considerably augmented 

 in a twelve months' season, as they are yielding nearly 1 lb. fat on the

 Progeny, ' ' Bloomer of Gowrie Park. ' ' 



last day; so that the return would be in the vicinity of £17 per head; 

 aJso the value of the skim milk, rich in non-fatty solids, which, in these 

 days of high prices, is worth at least 2d. a gallon, but for comparative 

 purposes is put at Id. per gallon, equals £2 10s. In addition must be 

 added the value of the pure calf, which, in the case of the above heifers, 

 is easily worth £20. Seeing, then, that at two years three months, 

 which is slightly above the average, they started to produce, if they 

 had begun at three years old, the above-mentioned returns would be lost. 

 Such heifers can be reared for £7 —
