opponent out of position.

8. "Cock fight": Contestants hop on one leg with the arms folded closely over the chest. Object: by butting with the fleshy part of the shoulder without raising the arms, or by dodging to make the opponent change his feet or touch the floor with his hand or other part of his body.

9. One-legged tug of war: Contestants hop on one leg and grasp hands firmly. Object: To pull the opponent forward or make him place the raised foot on the floor.

10. The "siege": One contestant stands with one foot in a circle 14 inches in diameter, the other foot outside, and the arms folded as in 8. Two other contestants, each hopping on one leg, endeavor to dislodge the one in the circle by butting him with the shoulder. The besieged one is defeated in case he raises the foot in the circle, or removes it entirely from the circle. The besiegers are defeated in case they change feet or touch the floor as in 8. As soon as either of the latter is defeated his place is immediately filled, so that there are always two of them. The besieged should resort to volting, ducking, etc., rather than to depend upon his strength.

11. One-armed tug: Contestants stand facing each other; right hands grasped, feet apart. Object: Without moving feet, to pull the opponent forward. Shifting the feet loses the bout.

12. "Tug royal": Three contestants stand facing inward and grasp each other's wrists securely with their feet outside a circle about three feet in diameter. Object: by pulling or pushing to make one of the contestants step inside of the circle.

13. Indian wrestling: Contestants lie upon the ground face up, right shoulders in close contact, right elbows locked; at one the right leg is raised overhead and lowered, this is repeated at two, and at three the leg is raised quickly and locked with the opponent's right leg. Object: to roll him over by forcing his leg down.

14. Medicine ball race. Teams of five or six men are organized and a track for each team is marked out. This track consists of marks on the floor or ground at distances of 4 yards. On each of these marks stands a man with legs apart, the team forming a column of files. At "ready," "get set," the contestants prepare for the race, and at "go," the first man in the column rolls a medicine ball, which he has on the floor in front of him, through his legs to No. 2, he in turn rolls it to 3, etc., when it reaches the last man he picks it up and runs to the starting place with it and, the others all having shifted back one mark, the rolling is repeated. This continues until the first man brings the ball back to the starting place and every man is in his original position. The ball should be kept rolling: each man, as it comes to him, pushing it on quickly. Any ball about 9 inches in diameter will answer; it may be made of strong cloth and stuffed with cotton waste.

SIGNALING

Signals and Codes

General Service Code. (International Morse Code.)

861. Used for all visual and sound signaling, radiotelegraphy, and on cables using siphon recorders, used in communicating with Navy.

THE MORE IMPORTANT CONVENTIONAL FLAG SIGNALS

For communication between the firing line and the reserve or commander in rear. In transmission, their concealment from the enemy's view should be insured. In the absence of signal flags the headdress or other substitute may be used.

(See par. 96 for the signals.)

Wigwag

Signaling by flag, torch, hand lantern, or beam of searchlight (without shutter)[6]

862. 1. There is one position and there are three motions. The position is with flag or other appliance held vertically, the signalman facing directly toward the station with which it is desired to communicate. The first motion (the dot) is to the right of the sender, and will embrace an arc of 90°, starting with the vertical and returning to it, and will be made in a plane at right angles to the line connecting the two stations. The second motion (the dash) is a similar motion to the left of the sender. The third motion (front) is downward directly in front of the sender and instantly returned upward to the first position. This is used to indicate a pause or conclusion.

2. The beam of the searchlight, though ordinarily used with the shutter like the heliograph, may be used for long-distance signaling, when no shutter is suitable or available, in a similar manner to the flag or torch, the first position being a vertical one. A movement of the beam 90° to the right of the sender indicates a dot, a similar movement to the left indicates a dash; the beam is lowered vertically for front.

3. To use the torch or hand lantern, a footlight must be employed as a point of reference to the motion. The lantern is more conveniently swung out upward to the right of the footlight for a dot, to the left for a dash, and raised vertically for front.

4. To call a station, make the call letter until acknowledged, at intervals giving the call or signal of the calling station. If the call letter of a station is unknown, wave flag until acknowledged. In using the searchlight without shutter throw the beam in a vertical position and move it through an arc of 180° in a plane at right angles to the line connecting the two stations until acknowledged. To acknowledge a call, signal "Acknowledgment (or) I understand (——front)" followed by the call letter of the acknowledging station.

Notes on Wig-wagging

5. In order to avoid the flag wrapping itself about the staff, stand facing the receiving station, with feet apart. Hold the staff with the left hand at butt and right hand 24 inches from end. In moving flag to the right, bring it down with an outward and inward sweep, and then return it to the vertical. When the tip is farthest down the staff inclines to the right front and as the flag is brought upward it is swept inward and upwards and as it approaches the vertical position it sweeps forward slightly. In moving to the left the motion is similar,—at the lowest point the staff inclines to the left front. A combination of right and left is made with a figure-of-eight motion.

In making "front" the flag is lowered and moved very slightly to the left front and then swept slightly to the right front, making a figure-of-eight.

The body should be twisted and bent at the waist in making the light and left motions.

Care should be exercised in keeping the flag in front of the body in making "front," the figure-of-eight is necessarily very flat.

Do not make letters in a careless slipshod manner.

The Two-arm Semaphore Code

(See Plates I and II)

863. Semaphore signaling may be done with or without flags. Without flags it is rarely dependable beyond 600 yards.

In sending stand with feet apart, squarely facing the receiver.

In making letters which require the use of both arms on the same side of body, twist the body to that side and bend at waist, so as to throw both arms well away from body. But be careful to keep arms in plane of original position of body.

When a letter repeats—bring both hands (if a two-armed letter) to chest after first, then make second.

Do not try to send rapidly so as to exhibit your ability. Remember that the receiver's ability determines the speed to be used. Anyone can send faster than he himself can receive. If you want to display your skill have some one send rapidly to you.

In receiving, if you miss a letter—let it go and get the others. If you miss a word signal—"O" (waving flags or arms) and signal the last word you have received.

Rapidity is secondary to accuracy.

Take the positions for the various letters accurately. The horizontal position should not incline upward nor downward. In making an "L," for example, if the left arm is midway between its proper position and the horizontal it is difficult to tell whether it is L or M.

In making D, J, K, P, T, and V, the arm in the vertical position should be brought exactly in front of the body by carrying the shoulder in almost under the chin, twisting the elbow in until it is directly before the eyes, and the forearm held in the vertical position with the palm to the rear. When so done there is no possibility of this position being mistaken for any other.

"Manila Milkman" may be sent without changing the position of the right hand. In making I, be sure to twist body well to the right in order that the left arm may be seen in the upper slanting position to the right. City and similar words may be so made.

D may be made with either hand.

Be sure how next letter is made before moving hands. Make no false motions.

Acquire accuracy; then try for speed.

"CHOP-CHOP." The "chop-chop" signal is made by placing both arms at the right horizontal (that is, by bringing the left arm up to the position of the right arm as in the figure for letter "B"), and then moving each up and down, several times, in opposite direction, making a cutting motion.

END OF WORD. After each word the "Interval" signal is made.

END OF SENTENCE. After each sentence the chop signal is made twice.

END OF MESSAGE. At the end of a message the chop signal is made three times.

ERROR. Signal "A" several times quickly, followed by interval; then repeat the word.

TO BREAK IN. Signal "Attention."

NUMERALS. Numbers are always preceded by the signal, "Numerals." After "Numerals" has been signaled, everything that follows will be numbers until "Interval" is signaled, after which what follows will be letters.

Signaling with heliograph, flash lantern, and searchlight (with shutter)[7]

864. 1. The first position is to turn a steady flash on the receiving station. The signals are made by short and long flashes. Use a short flash for dot and a long steady flash for dash. The elements of a letter should be slightly longer than in sound signals.

2. To call a station, make the call letter until acknowledged, at intervals the call or signal of the calling station.

3. If the call letter of a station be unknown, signal a series of dots rapidly made until acknowledged. Each station will then turn on a steady flash and adjust. When the adjustment is satisfactory to
