What qualities should such an honoured servant of society exemplify in his person? In my opinion an ideal Bhangi should have a thorough knowledge of the principles of sanitation. He should know how a right kind of latrine is constructed and the correct way of cleaning it. He should know how to overcome and destroy the odour of excreta and the various disinfectants to render them innocuous. He should likewise know the process of converting night- soil and urine into manure.
