Smoke Signals

Smoke.

Typically coded:

one puff: Attention

Two puffs: All's Well.

Three puffs...Danger.

We must stand at a high point for this to be seen. Create a secret code so the enemy can't decipher the visible smoke.

Have we all looked up at the smoke drifting up from our cigarette. Searching for answers? Signals? Who knows our code? If we slouch very low will it soar up high enough?

Big circles. Small circle. Falling back down. How many drags did I take?

Take my Polybius square.

I want your petroglyphs. All those ideograms and alphabets.

Morse code.

Intimate signal lamps and and semaphore line.
