“Listen carefully, Senor Snake, and make no move until you have heard. The Snake has but one shot. The Snake cannot tamper with his blindfold. If he so tampers it is our duty to see that he immediately dies. The Snake has no time limit. He may take the rest of the day, and all of the night, and the remainder of eternity ere he fires his one shot. As for the Bird, the one rule is that never must the bell leave his hand, and never may he stop the clapper of it from making the full noise intended of the clapper against the sides of the bell. Should he do so, then will he immediately die. We are here above you, both of you Senors, rifles in hand, to see that you die the second you infract any of the rules. And now, God be with the right, proceed!” The Jefe turned slowly about and listened, while Henry, essaying gingerly to move with the bell, caused it to tinkle. The rifle was quick to bear upon the sound, and to pursue it as Henry ran. With a quick shift he transferred the bell to the other extended hand and ran back in the opposite direction, the rifle sweeping after him in inexorable pursuit. But the Jefe was too cunning to risk all on a chance shot, and slowly advanced across the arena. Henry stood still, and the bell made no sound. So unerringly had the Jefe’s ear located the last silvery tinkle, and so straightly did he walk despite his blindfold, that he advanced just to the right of Henry and directly at the bell. With infinite caution, provoking no tinkle, Henry slightly raised his arm and permitted the Jefe’s head to go under the bell with a bare inch of margin. His rifle pointed, and within a foot of the pit-wall, the Jefe halted in indecision, listened vainly for a moment, then made a further stride that collided the rifle muzzle with the wall. He whirled about, and, with the rifle extended, like any blind man felt out the air-space for his enemy. The muzzle would have touched Henry had he not sprung away on a noisy and zig-zag course. In the center of the pit he came to a frozen pause. The Jefe stalked past a yard to the side and collided with the opposite wall. He circled the wall, walking cat-footed, his rifle forever feeling out into the empty air. Next he ventured across the pit. After several such crossings, during which the stationary bell gave him no clue, he adopted a clever method. Tossing his hat on the ground for the mark of his starting point, he crossed the edge of the pit on a shallow chord, extended the chord by a pace farther along the wall, and felt his way back along the new and longer chord. Again against the wall, he verified the correctness of the parallelness of the two chords, by pacing back to his hat. This time, with three paces along the wall from the hat, he initiated his third chord.
