as we have learned , much to the sorrow of the overmind , the man-things have many sticks with teeth with which they can cause hurt-and even death-to the servants of the vlagh , but these sticks with teeth are not parts of their own bodies , but are separate and may easily be carried away by those of us which serve our dear vlagh , and the overmind in its wisdom advised us to gather up those sticks with teeth which had been carried by man-things which had died during our struggles with them .
