MALLERY.] CHEYENNE AND ARAPAHO SIGNALS. 543 
When a war party encamps for a night or a day or more, a piece of 
wood is stuck into the ground, pointing in the direction pursued, with 
a number of cuts, notches, or marks corresponding to the number of 
days which the party spent after leaving the last camp until leaving the 
present camp, serving to show to the recruits to the main party the 
course to be followed, and the distance. 
A hunting party in advancing takes the same precautions as a war 
party, so as not to be surprised by an enemy. If a scout ascends a 
prominent elevation and discovers no game, the blanket is grasped and 
waved horizontally from side to side at the height of the shoulders or 
head ; and if game is discovered the Indian rides back and forth (from 
left to right) a short distance so that the distant observers can view the 
maneuver. Ifa large herd of buttalo is found, the extent traveled over 
in going to and fro increases in proportion to the size of the herd. A 
quicker gait is traveled when the herd is very large or haste on the part 
of the hunters is desired. 
It is stated that these Indians also use mirrors to signal from one 
elevation to another, but the system could not be learned, as they say 
they have no longer use for it, having ceased warfare (?).
