This chunk of limestone lies close to a hedge in the school yard. There are millions like it along the shore at Enniscrone. Four hundred million years ago, our area was under the sea and limestone was formed from tiny particles of lime in the water. When the sea-water evaporated, the lime sank to the bottom of the sea. It covered plants and dead creatures and hardened around them. Sometimes we see lime in our kettles. When the water boils off, the lime is left behind. People burned the limestone in Stokane to make lime about 50 years ago. There is a lime kiln close to the school.
