WHERE DOES THE DUST GO?

UST is made of very different things, and its fate varies accordingly. Some dust is mainly made of particles of carbon, and these are gradually washed into the soil by the rain. We do not know whether they are useful there. Some of them get into our lungs and stay there. Then much dust is made of organic matter-substances derived from ‘living creatures, such as horses, for example. These street deposits of animals are a very important part of town dust. They find their way into the sewers, and so to the seas; or often to the soil, where, like all organic matter, they are extremely useful for the growth of vegetable life. This dust often gets into our eyes and throats, and probably helps to cause the colds that are so common in towns. ; Town dust will be really healthier when horses, dogs, and cats are kept under. better control-if, indeed, they are allowed in towns at all.
