If, in the rainy season, the water should be without flavour or the sky of the colour of the cows eye or clear and without clouds or if salt should turn into water or if the colour of the sky should be that of the crows egg or if the atmosphere should be still and no wind should blow or if the fish should be found to jump from water on the bank or if the frog should be heard to croak incessantly, there will be immediate rain.
