As he swung into the saddle, following his visit to Aunt Nettie, a flush of shame and anger, which even the terrors of that formidable spinster could not suppress, showed through the bronze on Mr. Masterson’s face. The taunt about being in Dodge when he ought to be over on the Cimarron, harvesting a vengeance, had stirred him deeply. To have it intimated that his courage was slow, and his friendship cool, wore sorely on the soul of Mr. Masterson. It was the harder to bear when flung from the tongue of a woman; for his hands were tied, and his mouth was closed against resentment. “One thing,” thought Mr. Masterson, by way of self-consolation, “the man never made a moccasin track in Dodge who could have said as much and got away. Aunt Nettie’s right though; I ought to be evening up for Billy right now.” Time stood a week later, and along the shallow Cimarron—as in every other region civilised or savage—it was Christmas night. The weather was mild, the bare earth without frost, while on the slow wind creeping in from the north there rode the moist odour of snow. The moon, old and on the wane, was swinging low in the western sky, and what dim lights it offered were made more dim by a constant drift of clouds across its yellow face. Scattered along the north bank of the Cimarron, a straggling mile or more, stood the tepees of Bear Shield’s people. It was well beyond midnight, and nothing vocal about the camp save the occasional short yelp of a dog, made melancholy by the hour’s lonesomeness. Now and then an ember of some dying fire burned for a fierce moment, and then blinked out. Mr. Masterson, riding slowly down the opposite bank, and taking shrewd care to keep deep within the shadow of the woods, counted seventy-two lodges—a probable population of seven hundred and twenty, for a plainsman’s census argues ten to a lodge. Mr. Masterson had located the band of ponies, which made up the riches of Bear Shield, late in the dull gray afternoon, while he lay hidden in a dry arroyo. As it grew darker, he had crept nearer, keeping ever the location of the ponies which, in a rambling, ragged herd, were grazing up the wind. Mr. Masterson, on the south bank of the Cimarron, was heedfully to leeward of the herd; a proper piece of caution, for an Indian pony, at the earliest paleface taint to alarm the breeze, will scream like a wronged panther. Arriving at the place where he meant to ford the river and begin his drive, Mr. Masterson halted for a cloud of unusual size and thickness to blanket the blurred radiance of the dwindling moon. Such a cloud was on its way; from where it hung curtain-wise on the horizon it should take ten minutes before its eclipse of the interfering moon began.
