San Patrick day

hello everyone between now and Thursday in English class we Sant Patrick.
Howrah we will see some symbols.
Symbol number 1. The leprechaun.
  Legend has it that if you find the pot of leprechaun gives you. One trick to know how to find a pot is to look at the end of a rainbow.
To see if you find one.

Symbol # 2. The green color.
I can not tell you what that is a long story.

Symbol # 3. The three-leaf clover.
Another long story.
