High in the Black Mountains, on the windswept slopes of Mount Plynlimon,
three sisters met to discuss the weighty problem of what was the best
way to the sea - for, being water spirits, they were fond of the oceans.
The first decided to take the direct route, and headed westward. She
became the river Ystwith, and was the first to mingle with salty waters.
The second sister had a taste for landscape, and made her way through
purple hills and golden valleys - her name was Wye. The remaining sister
decided against short-cuts and it took her 180 miles to reach the sea,
The Severn.
