Hazel, Ogham name Coll, rules 5th August to 1st September. Around Connla's well grew the nine Hazel trees which contained all the knowledge of the world. From those trees dropped nine nuts, which imparted this knowledge to the salmon living in the well who ate them. Fionn cooked the salmon for the chief Druid to eat, but burnt his thumb on the cooking fish and sucked it to ease the pain, gaining the wisdom instead of his master.
