Note that this procedure is equivalent to taking a Shadow-Tip Method reading (par. 1), the only difference being that you observe t!ie star's movement directly, rather than that of the shadow tip on the ground. The latter is a re-flcction of the star's movement, with identical results.
As an alternative method, implant the slick vertically. Lying down, eight dlonj» the scick with your eye (like a rifle sifcht) to any overhead star, and observe its direction of movement.
c. MOON - If the moon is bright enough to cast a distinct shadow, use the Shadow-Tip Method (par. J) che same as in daytime to obtain an approximate east-west line. Persons having a watch can make a shadow-clock and use the Ower.doff Watch Method (par. 41, which will avoid the 10-minute wait for subsequent readings. However, for time-telUng purposed, remember tHe moon shadow-clock time may be quite different from regular clock time or sun ahadoxu-clock time.
Shculd the moon be dim, drive an at least 4-foot stick (which may be inclined) Into the grcur.d. Lying down, establish a lire of sight through the tip of the stick to the moon. Without moving your head, wait a :>v minutes to observe,the moon's direction of movement.
As with the sun and stars, the moon always moves generally from east to west.
6. POCKET NAVIGATOR (FIGURE 5) - This is an original dcvice for finding crue daytime direction by means of shadow-tip curves. The navigator is intended primarily for troop training in the continental U.S. (48 states), but it will w«jrk anywhere around the world at the same latitude band.
a. Place a 1-lnch pin vertically at the "cross, " and scat it securely. Check by eye to ensure that the pin la Iruly uprtght. Press elbows firmly against sides, pull card taut with thumb and forefinger at cach end, and face the sun.
b. Close one eye and look straight down at the pin with the other.
Keep pinhead Just covering the "cross" while you swivel from the htpi until the shadow tip just touches the proper month curve. Arrow now points true north. tfumbers on the csrve show time of day (sun time).
c. Use a.m. half of curve before noon, and p. rn. half in afternoon.
If not certain whether midday haa passed, take a shadow-clock reading, which will unerringly tell you. Or. lay th« navigator flat on the ground and observe
the changing shadow length. If it ahortens, it is morning. If il gets longer, it is afternoon.
d. The circles are for practice iri getting the card level. Experiment to find particular circle which Ihc shadow tip just follows an you slowly swivel from the hips (keeping une eye on the pinhead as described above). Interpolate between "level circles' if necessary.
e. Where "level circle" touches the month curve is where shadow tip shculd be when you take a reading. If shadow t;p is off card, let the shadow line just touch the very end of the month curve.
f. For 'in-between" dates, let the shadow tip touch the 'level circle1' at that point between month curves which roughly represents the actual date.
g. Keep several pins in yjur wallet to use with the navigator If ycu have no pin, use a stick to take shadow-tip readings for direction. The month curve on the navigator .s a 'map" of your course of travel during the day if frequent shadow-tip readings are taken to maintain direction. For example, if you wish to travel southeast, the "map' will be the same, bur it will be slanted southeasterly instead of easterly. If you don't have a watch to find out "where you are" on the curve, make a fchadow-cJock and correct your shadow.tip direction to true direction. (See page« <H c* 45 for navigator)
