'No coyote,' he said with positiveness. 'That track shows a foot four times as big as any coyote's that ever scratched fleas. Wolf? Maybe. It would be a whopper of a wolf at that. Look at the size of it, man! Why, the ugly brute would be big enough to scare my prize shorthorn bull into taking out life insurance. And that isn't all. That's just the front foot. Now look at the hind foot. Smaller, longer, and leaving a lighter imprint. All belonging to the same animal.' He scratched his head in frank bewilderment. 'It's a new one on me,' he confessed frankly. Then he chuckled. 'I'd bet a man that the gent who left on the hasty foot just got one squint at this little beastie and at that had all sorts of good reasons for streaking out.' A big lizard went rustling through a pile of dead leaves and all three of them started. Howard laughed. 'We're right near Superstition Pool!' he informed them with suddenly assumed gravity.

'I refer, you understand, to your hinting a moment ago at there being any truth in the old Indian superstitions. I am not to suppose, am I, that you actually give any credence to tales of supernatural influences manifested hereabouts?' Alan Howard stirred his coffee meditatively, and after so leisurely a fashion that Longstreet began to fidget. The reply, when finally it came, was sufficiently non-committal. 'I said "_Quien sabe_?" to the question just now,' he said, a twinkle in the regard bestowed upon the scientist. 'They are two pretty good little old words and fit in first-rate lots of times.' 'Spanish for "Who knows?" aren't they?' Howard nodded. 'They used to be Spanish; I guess they're Mex by now.' Longstreet frowned and returned to the issue.
