Rimrock Trail. Dunn Joseph Allan

we tackle that?" asked Sam, nodding at the shimmering view.

      "Better hold off for a while." Sandy took the lead, bending from the saddle, reading the trail that Grit's paws had left in the alkali and sand. Cactus reared its spiny stems or sprawled over the ground more like strange water-growths that had survived the emptying of an inland sea than vegetation of the land. Once the dog's tracks led aside to a scummy puddle, saucered by alkali, dotted with the spoor of desert animals that drank the bitter water in extremity. Then it ran straight to a wide reef of lava. Sandy set down the collie. Grit ran fast across the pitted surface, ahead of the horses, waiting for them to cross the lava. They had hard work to get him to come to hand again, but he gave in at last to the knowledge that they would not go on otherwise.

      "Sand's too hot fo' yore pads, dawg," said Sandy, "Raise the mischief with that tape. Shack erlong, Pronto. Give you a slice of Pedro's dried-apple pie when we git back, to make up for workin' you Sunday." The pinto tossed a pink muzzle and his master reached to pat the dusty, sweat-streaked neck. Alkali rose about them in clouds. Grit's trail, though blurred in the soft soil, was plain enough. The two riders went silently on at a steady walking gait. Talk in the saddle with men who make range-riding a business comes only in spurts.

      "Never see a prospector with a dawg afore," said Sam at last. "An' that a sheep dawg."

      "Dawg 'ud be apt to tucker out in desert travel," agreed Sandy. "Mean one more mouth fo' water."

      He, like Sam, speculated on the kind of man P. Casey – if it was Casey they were after – might be. If not a sheepman or a prospector, a third probability made him an outlaw, a man with a price on his head, hiding in the wilds from punishment. It sufficed to them that he was a man whom a dog loved enough to bear a call to help his master.

      Slowly, the mesa ahead took on more definite shape. The shadows resolved themselves into ravines and cañons. They entered a gorge filled with boulders and rounded rocks, over which the sure-footed ponies made clattering, slippery progress. Here and there the gaunt skeleton of a tree, white as if lime-washed, showed that once cottonwoods had flourished before the devouring desert had claimed the territory. The cactus was all prickly pear, the gray-green flesh of the flat leaves starred with brilliant blossom. Along one side of the cañon, mounting zigzag, showed the remains of a road, broken down by landslip and the furious rush of cloud-burst waters.

      Making this, finding it free of wagon sign or horse tracks, Sandy picked up Grit's trail once again. The collie wriggled, shot up its muzzle, whined, licked Sandy's face.

      "Nigh there," suggested Sam. Sandy nodded and let the dog get down. Grit raced off, nose high, streaking around a curve. When they reached it he was out of sight. The road had been built up in places on the outer edge with stones, dry-piled. They had fallen away, the grade following, so that sometimes all that was left for passage was a ledge along which the horses sidled carefully in single file, stirrups brushing the inside bank. The zigzags ended, the cañon narrowed, deepened. Sandy looked down to the dry bed of it four hundred feet below. The road rose at a steep pitch, cliff to the right, precipice to the left, stretching on and up to the summit of the pass.

      Suddenly Pronto shied violently, tried to bolt up the cliff, scrambling goatwise for twenty feet to stand shivering and snorting. Sandy's balance was automatic, the muscles of his knees clamped for grip, he gave the pinto its head, trusting to it to establish footing. He saw Sam's roan dancing in the trail, the led mare plunging, dust rising all about them. Left-handed, a Colt flashed out of Sandy's holster, barked twice, the echoes tossing between the cañon walls. In the road a rattlesnake writhed, headless, its body, thicker than a man's wrist, checkered in dirty gray and chocolate diamonds.

      "Git down there, you hysteric son of a gun," he said to the horse. "It's all over." The pinto hesitated, shifted unwilling hoofs, squatted on its haunches and, tail sweeping the dirt, tobogganed down to the road, jumping catwise the moment it was reached, away from the squirming terror. Sandy forced him back, leaned far down, tucked the barrel of the gun under the snake's body and hurled it looping into the gorge. Sam got his roan and the mare under control as the dust subsided.

      "More'n a dozen buttons," said Sandy. "Listen!"

      Grit, unseen, ahead, was barking in staccato volleys. There was another sound, a faint shout, unmistakably; human. The men looked at each other with eyebrows raised.

      "That ain't no man's voice," said Sam. "That's a gal." He looked quizzically at Sandy, knowing his chum's inhibition.

      Sandy was woman-shy. Men met his level glance, fairly, with swift certainty that here stood a man, four-square; or shiftily, according to their ease of conscience, knowing his breed. Sandy was a two-gun man but he was not a killer. There were no notches on the handles of his Colts. In earlier days he had shot with deadly aim and purpose, but never save in self-defense and upon the side of law and right and order. Among men his poise was secure but, in a woman's presence, Sandy Bourke's tongue was tied save in emergency, his wits tangled. Whatever he privately felt of the attraction of the opposite sex, the proximity of a girl produced an embarrassment he hated but could not help. He had seen admiration, desire for closer acquaintance, in many a fair face but such invitation affected him as the sight of a circling loop affects a horse in a remuda.

      He gave Sam no chance for banter. Action was forward and it always straightened out the short-circuitings of Sandy's mental reflexes toward womankind. He touched Pronto's flanks with the dulled rowels he wore, and the pinto broke into a lope. A big boulder was perched upon the nigh side of the road. Grit came out from behind it, barked, whirled and seemingly dived into the cañon. Coming up with the mare, Sam found Sandy dismounted, waiting for him.

      What had happened was plain to both of them. The rotten, hastily made road collapsed under the lurch of a wagon jolting over outcrop uncovered by the rains. Scored dirt where frantic hoofs had pawed in vain, tire marks that ended in side scrapes and vanished.

      Sam got off the roan, the tired horses standing still, snuffing the marks of trouble. Far down the slope Grit gave tongue. The cliff shouldered out and they could see nothing from the broken road. How any one could have hurtled over the precipice and be still able to call for help without the aid of some miracle was an enigma. They listened for another shout but, save for the barking of the dog, there was silence in the grim gorge. In the sky, two buzzards wheeled.

      Sandy poured a scant measure of water from his canteen into the punched-in crown of his Stetson, after he had knocked out the dust. Sam did the same, giving each horse a mouth-rinse and a swallow of tepid water so they would stand more contentedly. Each took a swift swig from the containers. Sandy untied the package of food and the leather medicine kit, Sam slapped his hip to be sure of his whisky flask. Aided by their high heels, digging them in the unstable dirt, they worked down the cliff, rounding the shoulder.

      A wide ledge of outcrop jutted out from the cañon wall jagged into battlements. Piled there was a wagon, on its side, the canvas tilt sagged in, its hoops broken. A white horse, emaciated, little more than buzzard meat when alive, lay with its legs stiff in the air, neck flattened and head limp. A broken pole, with splintered ends, crossed the body of its mate, a bay, gaunt-hipped, high of ribs. It lay still, but its flanks heaved, catching a flash of sun on its dull hide.

      Between the wheels of the wagon knelt a girl in a gown of faded blue, head hidden behind a sunbonnet. She leaned forward in the shadow of the wagon. Sandy caught a glimpse of a huddled body beyond her. Grit sat on his haunches, head toward the road, thrown back at each bark. Sandy reached the ledge first. The girl did not turn her head, though his descent was noisy. He touched her gently on the shoulder, telling himself that she was "just a kid."

      She looked up, her face lined where tears had laned down through the mask of dust. Now she was past crying. Her eyes met Sandy's pitifully, holding neither surprise nor hope.

      "He's dead." She seemed to be stating a fact long accepted.

      "He's dead. An' he made me jump. You come too late, mister."

      The man lay stretched out, head and shoulders hidden, his gaunt body dressed in jeans, once blue, long since washed and sun-faded to the green of turquoise matrix. The boots were rusty, patched. The wagon-bed, toppling sidewise, had crashed down on his chest. Rock partly supported the weight of it. Sandy picked up a gnarled hand, scarred, calloused
