A hunting trip

I heard there was treasure in the caves
Along the rocky sea-shore
So I picked up a spade
A basket with it,and a map
Then I wore my hiking shoes
And set up the stony cliff
The hike was rough
The weather tough
But I made it to the caves
Then I started inspecting
All the caves with my spade
Only one could be dug by spade
So I starting digging deep
Whew!It was hard work
And took quite some strength
I waited for the sound of metal hitting wood
But I waited in absolute vain
I dug for two hours
In the end I was completely exhausted
I sat down with my back
Resting on the stone wall
In my anger,I threw my spade away
The spade hit the wall
But the sound of hitting stone didnt come
Instead,it sounded like wood
When I examined it
I found it was the treasure!
I found jewels and lockets
And golden coins too
But I learnt a lesson about treasure hunting
Its not necessary for it to be buried!
