STEERING BY THE SUN

In the daytime, you can find your way using the Sun. Find a stick that’s about a metre long and fix it vertically into the ground. Place a stone on the tip of the stick’s shadow. Wait at least ten minutes, and then place another stone at the tip of the stick’s shadow. The line between the stones will point directly from east to west, the second stone at the east end, and the first stone at the west end.
