As we fled along the valley, and in a few moments heard the sound of the Indians pursuing us, my mind was chiefly occupied with considerations of the quality which we denominate fear. I perceived that this purely occasional passion had a very direct bearing upon my own especial science of archÆology. I reflected that had I been engaged in building a city at the moment when that irritating flight of arrows fell among us——the sting of one of which I still felt smarting upon my forehead——I should assuredly have ceased at once the building of that city, and should have moved rapidly away. And thus an excellently well-built city, that would have delighted archÆologists of the future, would have been lost to the world. Putting the matter yet more closely: here I had just found the sign for which I and my companions had been toilsomely searching for a considerable time; the sign which unquestionably would lead us to the most interesting archÆological discovery that ever had been made. And yet, instead of stopping to study this sign earnestly, that I might understand all the meaning of it, I was hastening away from it with all possible speed; and for no better reason than that certain barbarians, whose knowledge of archÆology was not even rudimentary, were pursuing me that they might take my life—an imperfectly expressed concept, by-the-way; for life can be taken only in the limited sense of depriving another of it; it cannot be taken in the full sense of deprivation and acquisition combined. These several reflections so stirred my bile against the Indians in pursuit of us that I began to have a curiously blood-thirsty longing for our actual battling with them to begin; for I was possessed by a most unscientific desire to balance our account by killing several of them. And I confess that this desire was increased as I looked at the dead body of poor Dennis, lying limply across the fore-shoulders of Rayburn's horse.

It was with real satisfaction, therefore, that I obeyed Rayburn's order to halt, that we might make ready for the fight to begin. The valley up which we had been riding had narrowed by this time into a strait way shut in between high and nearly perpendicular walls; and the place that Rayburn had chosen for us to make our stand in was the mouth of a caÑon setting off from the valley nearly at right angles. The walls of this caÑon came almost together above, far overhanging their bases, so that assault from overhead was impossible; some fragments of fallen rock made a natural breastwork for us to fight behind; and a little stream of pure, sweet water flowed at our feet. Had this place been made for us expressly it could not better have suited our purposes; and finding it so opportunely put fresh heart into us. There was not, of course, a shadow of resemblance between the two, but, somehow, I fancied that the place where we stood resembled my old class-room at Ann Arbor; and I actually found myself repeating the opening sentence of the address that I delivered when I was formally inducted into the Chair of Topical Linguistics. I mention this fact not because it is of the slightest importance in this present narrative, but because I think that it well illustrates the tendency towards illogical association that is so curious a characteristic of the human mind.

I was not able to observe this phenomenon attentively, for Rayburn hustled us all about so sharply that I had no available time just then for abstract thought. The mules and the horses and El Sabio were driven into the caÑon, and we were ranged behind the fragments of rock almost in a moment. Each man had his Winchester and revolvers in readiness, and a couple of cases of cartridges had been broken out from the packs and put where we all had easy access to them. While this work was going forward we could hear the Indians coming hotly up the valley, and we were barely ready for them when the foremost of their party came in sight.

"Wait a little," said Rayburn, quietly. "They don't know which turn we've taken, and they'll probably get into a bunch to do some talking, and then we can whack away right into the flock."

While we were thus making ready I could see that Fray Antonio was in great distress of mind. He was a very brave man, and I know that his strong desire was to fight with the rest of us. And yet, just as the Indians showed themselves, he deliberately turned his back upon them and walked away into the caÑon's depths. His very lips were white, and there were beads of sweat upon his brow, and I saw that his fingers twitched convulsively. I know what he wanted to do, and I saw what he did. If ever a man showed the high bravery of moral courage, Fray Antonio showed it then. Even Young, in whom I did not look for appreciation of bravery of that sort, said afterwards that it was the pluckiest thing he ever saw.

As Rayburn had expected, the Indians halted—but keeping more under cover than he had counted upon—and held some sort of a council. But it did not seem, from what we could see of their gestures, to relate to the way that we might have taken so much as to the caÑon in which we actually were concealed. They pointed towards the mouth of the caÑon repeatedly, and it struck me that in their motions there was a curious indication of dread or awe. One old man was especially vehement in gestures of this unaccountable nature; and when at last the younger men in the council seemed to revolt against his orders, this man, and all the older men with him, retired down the valley whence they had come.

The young men, left to themselves, hesitated for a moment, and then with a cry—as though for their own encouragement—came charging towards us in a body. As we got a full view of them we perceived with much satisfaction that their only arms were bows and arrows and long spears, and that there were not more than twenty men in the lot. And then Rayburn gave the order to fire. I confess that my hand so trembled as I pulled the trigger of my rifle that I was not at all surprised to find that the man whom I had fired at—a very tall, powerful young fellow, who seemed to be in command—was not hit; but a man just behind him dropped, and I had a queer feeling in my throat, and certain odd sensations in my stomach, as I realized that I had shot him. Indeed, I was so engrossed with meditations upon the curious ease with which a man's life is let out of him, that I quite forgot for some seconds to continue firing. The others, luckily, conducted themselves in a more practical manner; and the little whirlwind of balls which sped from the Winchesters made it wonderful, not that so many of the Indians fell dead or wounded, as that any of them remained alive and unhurt. But eight of them did survive their charge in the face of the storm of bullets that we pelted at them; and these—headed by the tall fellow, who seemed bullet-proof—came rushing at us over our breastwork of rocks, shouting and flourishing their long spears.

I cannot say very accurately what happened during the next five minutes or so, for one of the Indians came directly at me, and before I could at all stop him—for I found that shooting at him with my revolver did him no harm at all; and this struck me as odd, for I had repeatedly hit the mark while practising in the corral—he had prodded his spear through the fleshy part of my left arm. It hurt severely. He had aimed his thrust, doubtless, at my heart, and he certainly would have penetrated that vital organ had I not at that moment slipped, and so disarranged his aim. He pulled the spear out of my arm, which action also gave me great pain, and his manner indicated that he was about to thrust it into some other part of me; which he surely could have done, for I was wholly at a loss as to what measures should be taken to assure my own safety. Indeed, I was very well convinced that my life was as good as ended, and a curious flash of thought went through me that I cannot coherently remember, but that was in the nature of a query as to whether or not in a future state the many scientific truths which as yet are but imperfectly understood will be wholly revealed to us.

However, the opportunity that I confidently expected would be given to me in a moment to obtain an answer to this interesting question did not then occur. Just as the Indian was lunging at me—I can see his ugly face now, as I close my eyes and let my thoughts turn backward to that critical moment—there was a flash of some bright object before me, and then the Indian's entire head seemed to shut up suddenly, something like an opera-glass, and he went down to the ground like a stone. As I turned, I saw that my deliverance had come from Pablo, and even in that very exciting moment I observed with astonishment that the weapon with which he had slain the Indian was a great jagged sword—if the maccuahuitl can be called a sword—such as the Aztecs used in ancient times. I could not then conveniently stop to question him whence he had obtained that very interesting weapon, for there was another Indian already close upon me; and I am pleased to say—for I do not wish the belief to go abroad that scientific men are worse than useless in practical emergencies—that, without assistance from Pablo or from anybody else, I managed to pick up my rifle, and with the heavy iron barrel of that weapon, used clubwise, I mashed the head of that Indian into a perfect pulp. I know positively that I mashed it into a pulp, for I tried afterwards to measure it, and found that for craniological purposes it was utterly valueless.

Even had I required Pablo's aid in this encounter he could not possibly have given it to me, for he was himself just then very hotly engaged. Indeed, but for assistance that come to him from an unexpected quarter his life assuredly would have been lost. He was in the act of hauling back to strike at the fellow facing him, and he did not at all know that he was in imminent danger of a thrust in the back from a wounded wretch who, having struggled upon his knees, was using what little life was left in him to deliver yet another blow. Just at this critical instant it was that Fray Antonio dashed into the thick of the fighting, and covered Pablo's body with his own against this assault in the rear; so that, as the Indian struck, the knife only cut through the monk's habit and slightly scratched his arm, instead of making a hole between Pablo's shoulder-blades that would have let the life out of him. Young, who was close beside Pablo, saw what was going on, and checked it before further harm was done by turning quickly and shooting off the top of the wounded Indian's head; and then Fray Antonio retired out of the fighting in which, without himself striking a blow, he had taken so gallant a part.

So far as I was concerned, the fight was at an end when I had so cleverly mashed the head of my second assailant. No more Indians came at me, and as I looked around I perceived that this was for the excellent reason that there were no more to come. Two were just advancing on Young; who had them covered with his revolver, and dropped them, one after the other, in less time than is required to tell about it. The only other survivor among the enemy—at least the only one able to keep his feet—was the tall young chief, and he and Rayburn were just finishing the last round of what probably was as fine a fight as ever was fought. They were well matched in size and in weight; and if the Indian was any stronger than Rayburn, I can only say that he must have been a most wonderfully strong man. They were fighting on even terms; for the Indian was armed only with a short club, that he held in his left hand—and this left-handed method made him all the more awkward to deal with—while Rayburn, having emptied his revolver, was using as a club its heavy barrel.

As I caught sight of them, the Indian was in the act of springing forward and delivering a tremendous blow; but Rayburn most skilfully parried this blow by throwing out his rifle, still retained in his left hand, in such a manner and with such force that the Indian's arm—at the same time striking and being struck with the iron barrel—was broken just above the wrist. He gave a yell of pain, as he well might; but he was a plucky fellow, and instead of dropping his club he only shifted it to his right hand. He never had a chance to strike again with it; for in that same instant Rayburn swung his revolver at arm's-length through the air and brought it down on his head with a sound so muffled and so hollow that I can liken it only to the staving-in of the head of a full cask. For a moment, while Rayburn drew back to strike again, the Indian's body swayed heavily; and then all his muscles relaxed, and he fell heavily and limply to the ground—while his brains spurted out from the ghastly trench made by that mighty blow from back to front across the entire top of his skull.
