                    Find Which Direction Is South

     Do you have a good sense of direction? If not, please take

with you a compass. But if you forget to take a compass, you

can still find your way.

     It's never a good idea to imagine that the family member

who was entrusted (委托) with the job of map-reading actually

knows where the family is. You can tell by the slightly

confused load on their faces that nothing on the ground seems

to match the map. Never mind. The sun is shining and it's still

morning.If you don't know the exact time, you can still find

out where south is, but you'll need to be patient.

    ①Find a straight stick and put it in the ground in a place

where you can mark its shadow.

    ②Try to position the stick as vertically(垂直)as you can.

You can check this by making a simple plumb line (铅锤线)

with a piece of string and weight. You haven't got any string?

OK, use a thread from your clothes with a button tied at the

end to act as a weight.

    ③Mark the end of the shadow cast by the stick.

    ④Wait approximately half an hour and mark the end of

the shadow again.

    ⑤Keep doing this until you have made several marks.

    ⑥The mark nearest the stick will represent the shortest

shadow, which is cast at midday, when the sun is highest in

the sky and pointing to the exact south.

    ⑦Pick a point in the distance along the line between the

shortest shadow and the stick.

    ⑧That point is south of where you are.

    ⑨Now you can turn the map, like you did before, and

find which way you should be travelling.
