is come and the dusk of our desert basin deepens, their castle crags and turret peaks signal, with the red fire of the sunset, “good-night” to us who dwell in the gloom below. Even in the darkness we see their shadowy might against the sky, and feel the still and solemn mystery of their enduring strength under the desert stars. {2} This is a story of some people who lived in the Catalinas. If you would find more exactly the scenes of this romance you must take the new Bankhead Highway that, in its course from Tucson to Florence and Phœnix, runs for miles in the shadow of these mountains. From the old Mexican quarter of the city—picturesque still with the colorful life of the West that is vanishing—you go straight north on Main Street, where the dust of your passing is the dust of the crumbled adobe buildings and fortifications of the ancient pueblo that had its beginning somewhere in the forgotten centuries. Leaving the outskirts of the town your way leads over rolling lands of greasewood and cacti, down the long grade past the cemetery, past the Government hospital in the valley, to the bridge that spans the Rillito. From the little river you climb quickly up to the desert slopes that form the western base of the main range and that lie under their wide skies unmarked by human hands since the beginning of deserts and mountains. Beyond the famous Steam{3} Pump Ranch, some sixteen miles from Tucson, the road to Oracle branches off from the Bankhead Highway and climbs higher and higher until from a wide mesa you can see the place of my story—the mighty Cañada del Oro—the Cañon of Gold. {3} But if you know the way you may turn aside from the main road before you come to this new Oracle branch and take instead the old road that winds closer to the mountains and for several miles follows the bed of the lower cañon. It was along this ancient trail that the eventful and romantic life of this southern Arizona country, through its many ages, moved. This way, centuries ago, came the Spaniards—lured by tales of a strange people who used silver and gold as we use tin and iron, and who set turquoise in the gates of their houses. This way came the Franciscan Fathers to find in the Cañada del Oro gold for their mission at San Xavier. This way, from the San Pedro and the Aravaipa, came savage Apache to raid the peaceful farming Papagos and later to war against the pale-face settlers in the valley of the Santa Cruz.
