In ancient days, rivers were very conveniently arranged. The water flowed down one bank, and up the other, so that you could go either way without the least trouble. Those were the days of magic. People were then able to fly six or seven miles, and to light on the trees like birds, when they went out hunting. But now the world is decrepit, and all good things are gone. In those days people used the fire-drill. Also, if they planted anything in the morning, it grew up by mid-day. On the other hand, those who ate of this quickly-produced grain were transformed into horses.
