The ancients had a fable of a horse and a rider so attuned--so wholly one--that the brain of the man and the power of the horse were a single being, a wonderful creature to whom the impossible was easy play. And there is good foundation for the myth. Who that has ridden on the polo field or swung the lasso behind the bounding herd, can forget the many times when he dropped the reins and signalled to the horse only by the gentle touch of knee, of heel, by voice, by body swing, by _wishing_ thus and so, and got response? For the horse and he were perfectly attuned and trained--the reins superfluous. Thus, centaur-like, they went, with more than twice the power that either by itself possessed. Fort Ryan where the Colonel held command, was in the Indian reserve and five miles south of Cedar Mountain. The life of the garrison was very self-contained, but Cedar Mountain had its allurements, and there were some entertainments where civilian and soldier met. The trail between was a favourite drive or ride and to Hartigan it became very familiar. There was one regular function that had a strong hold on him. It took place every other Saturday afternoon on the parade ground, and was called general riding exercises, but was really a "stunt show" of trick riding. After they began to know him, the coming of Hartigan with his horse was hailed by all with delight. The evenings of these festal days were spent in the gymnasium, when there was an athletic programme with great prominence given to sword play, boxing, and singlestick, in which Hartigan was the king; and here his cup of joy was full. "Ain't it a shame to waste all that stuff on a preacher?" was the frequent expression of the soldiers. Though what better use they would have made of it, was not clear. Many a dark night Hartigan rode home from the Fort after the evening's fun was over leaving it entirely to his horse to select the road, after the manner of the wise horseman. In mid-August there had been one of the typical Black Hill storms. After a month of drought, it had rained inches in a few hours. The little Rapid Fork of the Cheyenne was a broad flood which carried off most of its bridges, including that on the trail to the Fort. The rain had ceased the day before, but the flood had subsided very little by Saturday night as Hartigan mounted Blazing Star and set out for the fortnightly affair at Fort Ryan.
