104 CLIMATE AND RESOURCES OF UPPER INDIA. 



management and giving up irrigation, the reh- covered lands 

 may be made to produce double or quadruple the crops they 

 ever did with irrigation. Proper management is all that is 

 required. We must undo all that has been done by irrigation 

 to these lands, and commence a new system. By deep culti- 

 vation and manuring we must keep the soil loose and open, 

 and thus we shall prevent water and the salts in solution rising 

 to the surface by capillary attraction, and at the same time, by 

 preventing loss of rain-water by evaporation, we shall encourage 

 the downward nitration of the water, and replenish the deeper 

 springs, and the salts will remain diffused in the soil at a 

 sufficient depth from the surface to supply the wants of plants 

 for ages, and still not be in such excess in the upper soil 

 as to be injurious. A few experiments carefully carried out 

 would prove the correctness or otherwise of the system I 

 advocate, and their cost would be trifling. 



Rain-water has two duties to perform, to furnish moisture 

 for crops, and to replenish the deep-seated springs. Where 

 drainage, either surface or subsoil, is carried out throughout 

 a country, the springs must suffer, and the water-supply will 

 be deficient in dry seasons.
