204 THE PRACTICAL SIDE OF 



upon grass-land is followed by an increase 

 in the yield of milk. This fact has been 

 amply demonstrated on the farm attached 

 to the Midland Agricultural College near 

 Derby. Two plots of land, each four acres 

 in extent, were dressed with 10 cwt. of ground 

 lime per acre. One of these plots, however, 

 received in addition to the lime 4 cwt. of super- 

 phosphate and 1| cwt. of sulphate of potash 

 per acre. Cows were fed upon both plots 

 during three seasons, with the result that 

 while the yield of milk upon the unmanured 

 land was 5586 lb., it reached 8921 lb. 

 on the land receiving the phosphates and 

 potash. In the first year the increase in 

 the milk reached 84 gallons, in the second 

 86 gallons, and in the third year 81 gallons. 

 At a value of 6d. per gallon the total profit 

 returned per acre after the deduction of the 

 cost of the manure was £4 16s. 6d. It was 

 not only found that the manured land pro- 

 duced more milk, but that it kept more 

 stock. The small holder may therefore 

 take it for granted that by the judi- 

 cious employment of phosphatic manure 

 he will be able to keep more stock upon 

 his land, and, in consequence, produce more 

 milk
