You can draw straight lines on the globe. This is
usually hard to do. You can't use a ruler on a curved surface.
However, your globe sits in a cradle that has a ring around it. This
ring is the Horizon Ring.
Because your globe sits halfway on this cradle, you can draw a straight
line from one place to another.
A straight line on a globe is important because it shows true direction.
The picture below shows how you can use the globe and the mounting
to do this.

 |
 |
Step 1
Circle any two cities,
say Chicago and Moscow.
|
Step 2
Place your left thumb on Chicago and
your right on Moscow.
|
 |
 |
Step 3
Move the globe forward until
Chicago and Moscow are even
in the Horizon Ring.
|
Step 4
Draw a line, using the Horizon Ring as a
straight edge connecting the two cities. |
