"Say, kid," he remarked, after some time, "what does J stand for?" "J? Oh, my name! Jock." "Well, Jock, will y'u explain to me as a friend how y'u ever come to be such a fool as to leave yer home--wherever and whatever it was--in exchange for this here God-forsaken and iniquitous hole?" "If you'll explain to me," said the boy, greatly heartened, "how you come to be ridin' in the company of a fool, instead of goin' to your job at Tucson." The explanation was furnished before Specimen Jones had framed his reply. A burning freight-wagon and five dismembered human stumps lay in the road. This was what had happened to the Miguels and Serapios and the concertina. Jones and Cumnor, in their dodging and struggles to exclude all expressions of growing mutual esteem from their speech, had forgotten their journey, and a sudden bend among the rocks where the road had now brought them revealed the blood and fire staring them in the face. The plundered wagon was three parts empty; its splintered, blazing boards slid down as they burned into the fiery heap on the ground; packages of soda and groceries and medicines slid with them, bursting into chemical spots of green and crimson flame; a wheel crushed in and sank, spilling more packages that flickered and hissed; the garbage of combat and murder littered the earth, and in the air hung an odor that Cumnor knew, though he had never smelled it before. Morsels of dropped booty up among the rocks showed where the Indians had gone, and one horse remained, groaning, with an accidental arrow in his belly. "We'll just kill him," said Jones; and his pistol snapped idly, and snapped again, as his eye caught a motion--a something--two hundred yards up among the bowlders on the hill. He whirled round. The enemy was behind them also. There was no retreat. "Yourn's no good!" yelled Jones, fiercely, for Cumnor was getting out his little, foolish revolver. "Oh, what a trick to play on a man! Drop off yer horse, kid; drop, and do like me. Shootin's no good here, even if I was loaded. _They_ shot, and look at them now. God bless them ice-cream freezers of yourn, kid! Did y'u ever see a crazy man? If you 'ain't, _make it up as y'u go along_!" More objects moved up among the bowlders. Specimen Jones ripped off the burro's pack, and the milk-cans rolled on the ground. The burro began grazing quietly, with now and then a step towards new patches of grass. The horses stood where their riders had left them, their reins over their heads, hanging and dragging. From two hundred yards on the hill the ambushed Apaches showed, their dark, scattered figures appearing cautiously one by one, watching with suspicion. Specimen Jones seized up one milk-can, and Cumnor obediently did the same. [Illustration: THE MEXICAN FREIGHT-WAGON]
