C, sometimes read as K, is Coll, which is the Hazel tree. August is known as the Hazel Moon, because this is when Hazel nuts appear on the trees -- the world Coll translates to "the life force inside you", and what better symbol of life than the nut itself? Hazel is associated with wisdom and creativity and knowledge. Sometimes it is connected in Celtic lore with magical springs, sacred wells, and divination.
Hazel was a handy tree to have around. It was used by many English pilgrims to make staffs for use upon the road -- not only was it a sturdy walking stick, it also provided a modicum of self-defense for weary travelers. Certainly, it could have been used as well for ritual. Hazel was used in weaving of baskets by medieval folk, and the leaves were fed to cattle because it was believed this would increase the cow's supply of milk.
In the Irish myth cycles, there is a tale that nine hazel nuts dropped into a sacred pool. A salmon came along in the pool and gobbled up the nuts, which then imbued him with wisdom. A variation of the story appears in the legend of Finn Mac Cumhail, who ate the salmon and then took on the knowledge and wisdom of the fish. Note that Mac Cumhail is often translated as Mac Coll.
