Land manured with crude nightsoil, per acre 48 tons 



2 cwts. by weight of sugarcane. 

 Land manured with nightsoil supplied in irrigation water, 



per acre 49 tons 6 cwts. by weight of sugarcane." 



The use of nightsoil produced an increase of 

 29 tons 2 cwts. over the unmanured plot ; and when 

 we consider that this increase represents some- 

 thing like Rs. 150 while the outlay on manure was 

 only Rs. 20, we cannot but admit that rational agri- 

 culture with inexpensive manure ought to be one of 

 the most remunerative undertakings for a capitalist. 



Nightsoil and village sweepings are suited as 

 manure for all crops and food -stuffs consumed by 

 mankind, as they contain all the mineral constituents 

 of plant-food. The composition of a manure consist- 

 ing of human and animal refuse, village sweepings, 

 and dry earth prepared in the manner detailed 

 before, would almost equal that of farm-yard 

 manure, the ashes of which have been shown by an* 

 analysis by Liebig to consist of the following 

 percentages : 



Potash 2-7 



Soda 2-7 



Lime 8-2 



Magnesia TO 



Oxide of Iron 1-8 



Chloride of Sodium 2-7 



Phosphoric Acid 6*4 



Sulphuric Acid 3'6 



Carbonic Acid 4'5
