The drainage where tiles were used, cost, according to his estimate, 20 Rs. or £2 per acre. 50,000 square miles are, according to " Forecast of Expenditure on Canals" (mentioned on page 73), to be secured from liability to drought by irrigation- works, at an expenditure of some £20,000,000. If by this it is meant that an area of 50,000 UPPER INDIA. 103 square miles, or 32,000,000 acres,is to be irrigated at the above cost, then the cost of irrigational works is, in the first case, 12s. 6d. per acre; but as irrigation produces "reh "on the surface of the land, it is suggested an expenditure of £2 per acre be incurred to get rid of the reh. A certain sum having been spent in endeavours to improve the land, which endeavours, instead of improving, have caused deterioration, it is proposed to expend more than three times the original sum in endeavours to mitigate the injurious effects of the first injudicious expenditure. Leaving aside the question of expense, where could the fuel be found to burn the tiles? Supposing subsoil-drainage were carried out, and the reh were carried away by the drains, would this be beneficial or hurtful to the country? It is generally admitted that reh rises by capillary attraction from the subsoil in a state of solution. Such being the case — and I believe it is not disputed, the lands now covered with reh, and sterile from its effects, must have held the reh (except such as may have been brought in the water used for irrigation) in the subsoil at the time they were fertile and bearing good crops, viz. the first few years after they were irrigated ; thus showing that land containing the salts composing " reh " in the subsoil, are not sterile but fertile. Getting rid of the reh by the drains might be the means of securing good crops for a few years; but as the salts composing reh are in moderate quantities absolutely necessary for vegeta- tion, we might be securing a temporary benefit at the cost of a permanent loss to the country. We might benefit the present generation by ruining posterity. Many people look on lands once covered with reh as irre- claimably barren. I do not take such a pessimist view of the case ; I look on reh as a safeguard thrown up by nature to protect herself from further spoliation, and as a warning to man not to violate her laws ; and I believe that by judicious 104 CLIMATE AND RESOURCES OF UPPER INDTA. 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. Kain-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.
