[Three men, saw, and undercut in douglas fir]
B&W photograph depicts three men standing in front of douglas fir tree with undercut.
Written on verso: "Picture shows the undercut chopped by double bit axes. Purpose of the undercut is to determine the direction in which the tree will fall. The next process to be followed by the men in the picture will be to cut through from the opposite side of the tree with a crosscut saw. The saw cut will be four or six inches higher than the base of the undercut."
