irrigation either from streams or wells should be carefully studied. If 

 pumps have to be used, their efficiency should be tested from time 

 to time, or if the water is delivered by canals the leakage or seepage 

 should be determined by measurement, as no good management can 

 be had where the losses are not known, and knowing where losses occur 

 is the first step towards preventing them. This is just as important 

 in the fields as in the factory.
