"Must have howitzers," muttered Driscoll. The soft lead, bigger than marbles, went "Splut! Splut!" against the rock on all sides of him, flattening with the windy puff of mud on a wall. But he was well intrenched, and as the guerrillas were also, he lighted his pipe and smoked reflectively. But after awhile he perceived a slight movement, supplemented by a carabine. One of the besiegers was working from boulder to boulder, parallel with the trail. He did it with infinite craft. At first the fellow crawled; then, when out of pistol range, he got to his feet and ran. Still running, he crossed the trail at a safe distance beyond the hut, and began working back again, this time along the cliff, and toward Driscoll. When about a hundred yards away, he disappeared; which is to say, he lowered himself into a little ravine that thousands of rainy seasons had worn through from the foothills. But almost at once his head and shoulders rose from the nearer bank, and Driscoll promptly fired. The shot fell short. A pistol would not carry so far; which was a tremendously important little fact, since the other fellow was aiming a rifle. The bullet from that rifle neatly clipped a prickly pear over Driscoll's head. The strategist certainly knew his business. There was a familiar shimmer of silver about his high peaked hat. Yes surely, he was Don Tiburcio, the loyal Imperialist of the baleful eye. No doubt the malignant twinkle gleamed in that eye now, even as the blackmailer bit a cartridge for the next shot. A victim who had only pistols, and at rifle range, and with not a pebble for shelter from the flank bombardment--it was assuredly a situation to tickle Don Tiburcio. Now Driscoll's point of view was less amusing. To change his position, he must expose himself to a fusilade from across the way. And if he tried to rush his friend of the gully, the brigands meantime would carry off the two girls. A gentleman's part, therefore, was to stay where he was and be made a target of. But he varied it a little. At Don Tiburcio's second shot, he lunged partly to his feet and fell forward as though mortally wounded. He lay quite still, and soon Don Tiburcio came creeping toward him. Don Tiburcio was thinking of his lost toll-moneys that should be on the corpse. Driscoll waited, his nerves alert, his pistols ready. But just beyond range, the blackmailer paused. "Go for the women, you idiots," he yelled. "The Gringo's dead." The idiots verified the title straightway, for up they popped from behind their boulders and started for the shack.
