The Signal
Then Ogallah and one of his men held his blanket spread out so as almost to force the thick smoke to the ground, but such was not their purpose. The blanket was abruptly lifted, then swayed in a peculiar fashion, the two moving in perfect unison, without speaking, and repeating their pantomime with the regularity of machinery, for the space of fully ten minutes.
The results were singular. The inky column of vapor was broken into a number of sections, as may be said, so that when viewed from a distance the figure was that of a black broad band of enormous height, separated by belts of colorless air into a dozen pieces or divisions, the upper ones gradually melting into nothingness. Besides this, so deftly had the red men manipulated the fire and blanket, that these divisions showed a peculiar wavy appearance, which would have excited wondering remark, no matter by whom seen.
"It is a signal to some one on the ridge yonder," was the conclusion of Jack, who watched the proceeding with much interest.
Having finished, Ogallah and the warrior threw the blanket on the ground, and the whole five gazed at the ridge miles away. For a time perfect silence reigned, and then one of the dusky watchers uttered an exclamation, to which the chief responded with a grunt.
While scanning the distant ridge, Jack detected a black brush of vapor climbing slowly above the trees. It broke clean off, and as it went on upward, was inclosed by clear air on all sides. But it was not long before a second, third, fourth, and fifth appeared. Parties were answering the signal of the chief in precisely the same manner that he made it. The only difference was in the number, of which there were only the five. Those, however, were sufficient, as the parties making it were well aware.
This aboriginal system of telegraphy, which has been in use from time immemorial, is still a favorite means of communication among the Indians of the West. More than once the news of the signing of some important treaty, or the war movement of tribes, has been flashed by means of signal fires from mountain top to mountain top over a distance of hundreds of miles.
The information given by the answering signal fire was satisfactory to the chief Ogallah, who resumed the journey at a leisurely pace, making no effort to walk in the close Indian file that he and his warriors did when further away from home.
