Our latrines are perhaps most responsible for rendering the air impure. Very few people realise the serious harm done by dirty latrines. Even dogs and cats make with their claws something like a pit wherein to deposit their f ces, and then cover it up with some earth. Where there are no lavatories of the modern approved types, we should also do likewise. There should be kept ashes or dry earth in a tin can or an earthen vessel inside the latrine, and whoever goes into the latrine should, on coming out, cover the f ces well with the ash or the earth, as the case may be. If this is done there would be no bad smell, and the flies too will not settle on it and transmit the filth. Anybody whose sense of smell has not been wholly blunted, or who has not grown thoroughly accustomed to foul smells will know how noxious is the smell that emanates from all filthy matter which is allowed to lie open to the weather. Our gorge rises at the very thought of f ces being mixed with our food, but we go on inhaling the air which has been polluted by such foul smell, forgetting the fact that the one is just as bad as the other, except that, while the former is visible, the latter is not. We should see that our latrines are kept thoroughly neat and clean. [Pg 19] We abhor the idea of our cleaning the latrines ourselves, but what we should really abhor is the idea of making use of dirty latrines. What is the harm in ourselves removing the filth which has been expelled from inside our own body, and which we are not ashamed to have removed by others? There is absolutely no reason why we should not ourselves learn the work of scavenging and teach it to our children as well. The filthy matter should be removed, and thrown into a pit two feet deep, and then covered up with a thick layer of earth. If we go to some open place, we should dig a small pit with our hands or feet, and then cover it up, after the bowels have been evacuated. We also make the air impure by making water at all places indiscriminately. This dirty habit should be given up altogether. If there is no place specially set apart for the purpose, we should go to some dry ground away from the house, and should also cover up the urine with earth. The filth should not be cast into very deep pits, for, in that case, it would be beyond the reach of sun’s heat, and would also pollute the water flowing underneath the earth.
