The only sounds that would be heard were the clopping of her own hooves and the waving sound of the water in the tanks. For the rest it was as silent as a cemetery. The sounds of the sloshing water, its very rhythm had a strange but positive and relaxing effect upon the mare. If she didn't pay attention to her work, she found herself moving back and forth with the current of the waves.
