Racey was closer to the end of his rope than he realized.  At the instant that her free hand clutched at the rope it tightened with a jerk as the cow pony at the other end, feeling the strain and knowing his business, braced his legs and swayed backward.  Molly’s fingers brushed the back of Racey’s hand and swept down his arm.  Well it was for him that he had taken two turns round his wrist, for her forearm went round his neck and almost the whole downward pull of girl and horse exerted itself against the strength of Racey Dawson’s arm and shoulder muscles.

Molly’s face and chin were pressed tightly against Racey’s neck.  Small blame to her if her eyes were closed.  The arm held fast by the bridle was cruelly stretched and twisted.  And where the rein was tight across the back of her wrist, for he could reach no lower, Racey set the blade of his pocket-knife and sawed desperately.  It was not a sharp knife and the leather was tough.  The steel did not bite well.  Racey sawed all the harder.  His left arm felt as if it were being wrenched out of its socket.  The sweat was pouring down his face.  His hat jumped from his head.  He did not even wonder why.  He must cut that bridle rein in two.  He must—­he must.

Snap!  Three parts cut, the leather parted, Molly’s left arm and Racey’s right fell limply.  Molly’s horse went down the slide alone.  Neither of them saw it go.  Molly had fainted, and Racey was too spent to do more than catch her round the waist and hold her to him in time to prevent her following the horse.

Smack! something small and hot sprinkled Racey’s cheek.  He looked to the left.  On a rock face close by was a splash of lead.  Smack!  Zung-g-g diminuendo, as a bullet struck the side of a rock and buzzed off at an angle.

Racey turned his head abruptly.  At a place where trees grew thinly on the opposite side of the slide and at a considerably lower altitude than the spot where he and Molly hung at the end of their rope shreds of gray smoke were dissolving into the atmosphere.  The range was possibly seven hundred yards.  The hidden marksman was a good shot to drive his bullets as close as he had at that distance.

Straight out from the place of gray smoke four men and four horses were making their way across the slide.  They were halfway across.  But they had stopped.  The down rush of Molly’s horse had apparently given them pause.  Now two men started ahead, one stood irresolute and one started to retrace his steps.  It is a true saying that he who hesitates is lost.  Straight over the irresolute man and his horse rolled the dust cloud whose centre was Molly’s horse.  When the dust cloud passed on it was much larger, and both the man and his horse had disappeared.

The man who had started to retreat continued to retreat, and more rapidly.  The two who had held on did not cease to advance, but they proceeded very slowly.

“If that feller with the Winchester don’t get us we’re all right for a spell,” Racey muttered.
