content: A surveyor’s cross is used to lay out straight lines and lines at right angles to one another. There are two forms. The open form has four arms set at right angles to one another, with an open sight at each end. The closed form is solid, with four slits at right angles to one another; this seems to have been introduced around 1803 by William Jones, an instrument maker in London.
