Midnight
Your cow is your best surveyor . They came on the ranch suddenly , rounding a point into a small natural amphitheater . A flat-roofed dugout , fronted with stone , was built into the base of a boulder-piled hill ; the door was open . Midnight perked his black head jauntily and slanted an ear . High overhead , a thicket of hackberry and arrow-weed overhung the little valley . From this green tangle a pipe line on stilts broke away and straddled down a headlong hill . Frost was unknown ; the pipe was supported by forked posts of height assorted to need , an expedient easier than ditching that iron hillside .
