''In what respect?'

''Why, the interest that these folks who employ Pedro, take in this journey that I undertook for your friend, Señor Pride.'

''But, if this journey has some valuable secret object in view?'

''Valuable secret!' repeated Pepito, bursting into a fit of laughter; 'Yes, a valuable secret indeed! Oh! the joke of offering four hundred dollars for what, 'twixt you and me, is not worth a cent. But who can it be that is behind Pedro, in this matter? He must be some rival doctor, or else a naturalist, on the same scent.'

''Is Señor Pride,' I inquired, 'a doctor—are you sure of that?'

''Yes—he must be—but I don't know,' exclaimed Pepito; 'I am at my wits' end. If he is not, I have been working in the dark, and he has deceived me with a false pretext; I am at a loss—dead beat. But one thing is plain—I can make four hundred dollars, if I like.'

''And will you betray your employer?' said I indignantly.

''Time enough—never decide rashly, Caballero; I shall deliberate—nothing like sleeping on important affairs; to-morrow—who knows what to-morrow may bring forth?'

'So saying, Pepito arose, took his traveling sword under his arm, placed his hat jauntily on his head, cast an admiring eye at the looking-glass, and then brushed off some of the dust that still clung to his left sleeve.

''The smile of Heaven abide with you, Señor,' said he, with a most graceful bow. 'As for your friend's secret, do not be uneasy about it; I am not going to meet Pedro to-night. I shall take advantage of his absence to make a call on my lady-love. Pedro is a good fellow, but shockingly self-conceited; he fancies himself far smarter than I—perhaps he is—but somehow I fancy, this time he must be early if he catches me asleep.'
