This is their number: five Oghmic groups, i.e., five men for each group, and one up to five for each of them, that their signs may be distinguished. These are their signs: right of stem, left of stem, athwart of stem, through stem, about stem. Thus is a tree climbed, to wit, treading on the root of the tree first with thy right hand first and thy left hand after. Then with the stem, and against it and through it and about it. (Lines 947-951)
