PROFITABLE FARMING. 69 



Estimating the value of the milk at the low 

 price of 6d. per imperial gallon at the farm : 



251 Gallons of Milk at 6d. per gallon 



Less cost of production (Fertilisers) 



Total Net Profit per acre 4 16 



or an annual average net profit of i. I2s. 2d. 

 per acre. 



If the milk is valued at 8d. per imperial 

 gallon, the total clear profit is 6. i8s. 4d., or 

 2. 6s. id. per annum per acre. 



Here again the quick action of the water- 

 soluble phosphatic manure is to be noted. 

 Within three weeks- after application the bene- 

 ficial effect of the fertilisers was clearly visible, 

 and within six months of their application the 

 outlay was practically covered. But this is 

 not all ; there has been other grazing during 

 the remaining thirty weeks of each year which 

 is not included in these figures. 



We have no hesitation in stating that it is 

 only possible to realise such immediate returns 

 from a fertiliser in which the phosphate is water- 

 soluble. 



The speedy effects of water-soluble phosphate 

 are further confirmed by experiments at Hook, 

 Hants. The field, described as " a moss and 

 weed-ridden pasture, the soil being a gravelly 

 loam on gravel/' was manured on the 8th 

 February, 1912, two days previously lime, at 

 the rate of 10 cwt. per acre, having been applied 

 to some of the plots. About the middle of
