Summary: 
We will introduce W-trees of a W-graph which is a graph containing wild components. A wild component is an incompletely defined subgraph which is known to be a tree but what kind of the tree is unspecified. W-tree is defined as a set of edges and vertices of wild components obtained from a non-sigular major submatrix of a W-incidence matrix. The properties of a W-tree are useful for studying linear independent W-cutsets and so on in a W-graph.
