Making and using an A-Frame

The A-Frame is a tool which can be made at home from local resources. It is called an A-Frame because it looks like the English let-
ter "A". The A-Frame is used for marking out horizontal lines, or contours, across a slope. These can be used to dig ditches or plant trees which will prevent soil, nutrients and water from being washed away. In this chapter we'll read about how to make and use an A-Frame.
