General Miles introduced the heliograph into Arizona, in 1886, to improve the communications between army units hunting for Geronimo. The heliograph consisted of two mirrors mounted on a tripod. One was the sun mirror used to focus the sun onto the station mirror which was focused on a distant station. A second tripod held a shutter which could be opened and closed rapidly allowing the transmission of Morse Code.
Stations were established on mountain tops scattered over Arizona. A test message sent from the extreme eastern station to the extreme western station, a total distance of about 800 miles, required only four hours for transmission.
This set consists of a heliograph, an operator with code book, a Sergeant with binoculars an officer writing in his message book, and a station flag.
