A Dwarf Chestnut Tree
This bush-like tree is a fine example of a Burbank hybrid chestnut. The workman who stands beside the tree is five feet seven inches tall. Note the abundant crop of nuts on the tree and under the tree. Gathering chestnuts becomes a simple matter when the trees are of this type.
