Alarm
Three or more smoke columns reads impending danger from flood, fire or foe. This signal may be communicated from one camp to another, so as to alarm a large section of the country in remarkably quick time. The greater the haste desired the greater the number of smokes used. These fires are often so hastily made that they may resemble puffs of smoke caused by throwing heaps of grass and leaves upon the embers again and again.
Attention
"This signal is generally made by producing one continuous column and signifies attention for several purposes, viz., when a band had become tired of one locality, or the grass may have been consumed by the ponies, or some other cause necessitated removal, or should an enemy be reported which would require further watching before a decision as to future action would be made. The intention or knowledge of anything unusual would be communicated to neighboring bands by causing one column of smoke to ascend."
Establishment of a Camp, Quiet, Safety
"When a removal of camp has been made, after the signal for Attention has been given, and the party have selected a place where they propose to remain until there may be a necessity or desire for their removal, two columns of smoke are made, to inform their friends that they propose to remain at that place. Two columns are also made at other times during a long continued residence, to inform the neighboring bands that a camp still exists, and that all is favorable and quiet."
Therefore, Three or more smokes in daylight, or Three or more flames at night, is a signal of alarm, One smoke a signal for attention, Two smokes tells us that all is well, peaceful and happy.
Smoke Signals
The usual way of signalling with smoke is to make a smudge fire of browse or grass and use a blanket as an extinguisher. By covering the fire with the blanket and suddenly removing it, a large globular puff of smoke is made to suddenly appear, and is certain to attract the attention of anyone who happens to be looking toward the site of the fire.
