At General Carr's headquarters, among the willows close to the stream, a white flag, with a centre square of red, is fluttering in the breeze. It is one of the signal flags, but as the regimental standard had been left with the band at Fort Hays, the general adopted this for the double purpose of indicating his own position and of conveying messages to the distant outposts. Yesterday afternoon a group of our Indian allies, Crows and Shoshones, surrounded that flag with wondering interest from the moment of its first appearance. Accustomed to the use of signals themselves, they eagerly watch any improvement upon their system, and, learning from Sergeant Center, our standard-bearer and signal sergeant, that this was a "speaking flag," they hung around for hours to observe its operation. The herds of the different companies were browsing on the hillsides half a mile away, strong pickets being thrown out in their front, and each herd guarded by a sergeant and party from its own company. So General Carr, to give the Indians an idea of its use and at the same time secure more room, directed the sergeant to "Flag those Second Battalion herds to the other side of that ravine." So Center signalled "Attention" to the outposts, to which they waved "22, 22, 22, 3," the signal for "All right, go ahead, we're ready," and then, with the staring eyes of a score of swarthy warriors following his every move, Center rapidly swung his flag to form the message: "General Carr directs herds Second Battalion cross ravine." Speedily the grays of Company "B" and the four bay herds of the other companies began the movement, were slowly guided through the sorrels, blacks, and bays of the First Battalion, and commenced the descent into the ravine. One herd lagged a little behind, and the general, gazing at them through his binocular, quickly divined the cause. "Confound that herd guard; tell 'em to take off those side-lines when they're moving, if it's only a hundred yards." The message is sent as given, the side-lines whipped off, the horses step freely to their new grazing-ground, Crow and Shoshonee mutter guttural approbation and say that flag is "heap good medicine." Hours afterwards they are hunting about camp for old flour-sacks and the like, and several towels, spread on the bushes at the bathing-place below camp to dry in the sun, are missing.
