Explanation

_The Director_: “You will note that the situation indicates that the

advance guard is assumed to have been marching for two hours. This would

make the distance we have marched a little more than 5 miles. As a

matter of fact, we have only come a few hundred yards from our starting

point. You will have to draw on your imagination in this matter,

disregard all things behind you, and consider only those to the front.

It would consume too much time to actually go the distance assumed and

it is not necessary to do so, for we are now on new terrain, which

serves our purpose equally as well as if we were the full distance of 5

miles farther to the front.”
