Treasure hunters.

Here come Robert and Earl

Metal detectors in hand.
What sort of treasures, will they find at leisure
in the earth all over the land.

Archaeology wonders
Like a ring all silver and bright
Saxon? No ring pull, think its from red bull

Shame it bought them less delight

I heard near the village of Nutley
They had found a rare burial hole
Animal bones plenty, well least under twenty
and a collar and kitty cats bowl

Near Lewes  they had just started
when they found an object in the ground
Digging it roughly as ever so toughly 

They discovered the object was round

A cannonball? Said Robert just guessing 

Course it is. Answered Earl

Then it started humming and they started running
and they heard the explosion in Firle
