 as he will receive back more than twice its value in 

 the increased crop. 



In the series of experiments with chemical manures 

 made on the Madras Model Farm, the application 

 of saltpetre gave the following high results : 



It will thus be seen that a dose of about one cwt. 

 per acre nearly doubled the crop, and gave the 

 farmer a clear profit of nigh thirty rupees per 

 acre a result entirely due to the use of this manure. 



Similar results have been obtained in Europe, 

 and the utilization of this mineral manure is 

 therefore steadily increasing. It should be used 

 in quantities of one to two cwts. per acre, and 

 applied as a top-dressing when the plants are a 

 couple of inches high ; it will be well to mix it with 

 double its volume of dry earth or fine sand, so as 

 to ensure its more equal distribution. 



Saltpetre should never be used on a soil

 then an application of this manure will only result
