sun was hotter than it had been before. Many sounds now came from the camp below, but Ned, although he often looked eagerly, saw no signs of coming departure. Shortly after noon there was a great blare of trumpets, and a detachment of lancers rode up. They were large men, mounted finely, and the heads of their long lances glittered as they brandished them in the sun.
Ned's attention was drawn to the leader of this new detachment, an officer in most brilliant uniform, and he started. He knew him at once. It was the brother-in-law of Santa Anna, General Martin Perfecto de Cos, a man in whom that old, cruel strain was very strong, and whom Ned believed to be charged with the crushing of the Texans. Then he was right in his surmise that Mexican forces for the campaign were gathering here on the banks of the Teotihuacan!
More troops came in the afternoon, and the boy no longer had the slightest doubt. The camp spread out further and further, and assumed military form. Not so many men were lounging about and the tinkling of the guitars ceased. Ned could see General de Cos plainly, a heavy man of dark face, autocratic and domineering in manner.
Night came and the boy went once more to the palm. When he struck with his machete the water came forth, but in a much weaker stream. In reality he was yet thirsty after he drank the full flow, but he would not cut into the stem again. He knew that he must practice the severest economy with his water supply.
The third night came and as soon as he was safe from observation Ned slashed the palm once more. The day had been very hot and his thirst was great. The water come forth but with only half the vigor of the morning, which itself had shown a decrease. The poor palm, too, trembled and shook when he cut into it with the machete and the blades drooped. Ned drank what it supplied and then turned away regretfully. It was a kindly palm, a gift to man, and yet he must slay it to save his own life.
He lay down again, but he did not sleep as well as usual. His nerves were upset by the long delay, and the decline of the palm, and he was not refreshed when he awoke in the morning. His head felt hot and his limbs were heavy.
As it was not yet bright daylight he went to the palm and cut into it. The flow of water was only a few mouthfuls. Cautious and doubly economical now he pursed his lips that not a single drop might escape. Then, after eating a little food he lay down, protected as much as possible by the scanty bushes, and also sheltering himself at times from the sun with the serape which he drew over his head. He felt instinctively and with the power of conviction that the Mexicans would not depart. The coming of Cos had taken the hope from him. Cos! He hated the short, brusque name.
It was another day of dazzling brightness and intense heat. Certainly this was a vertical sun. It shot rays like burning arrows straight down. The blood in his veins seemed to dry up again. His head grew hotter. Black specks in myriads danced before his eyes. He looked longingly at his palm. When he first saw it, it stood up, vital and strong. Now it seemed to droop and waver like himself. But it would have enough life to fill its veins and arteries through the day and at night he would have another good drink.
He scarcely stirred throughout the day but spent most of the time looking at the palm. He paid no attention to the sounds below, sure that the Mexicans would not go away. He fell at times into a sort of fevered stupor, and he aroused himself from the last one to find that night had come. He took his machete, went to the tree, and cut quickly, because his thirst was very great.
The gash opened, but not a drop came forth.
CHAPTER V
IN THE PYRAMID
Ned stared, half in amazement, half in despair. Yet he had known all the while that this would happen. The palm had emptied every drop from its veins and arteries for him, giving life for life. He had cut so deeply and so often that it would wither now and die. He turned away in sadness, and suddenly a bitter, burning thirst assailed him. It seemed to have leaped into new life with the knowledge that there was nothing now to assuage it.
The boy sat down on a small projection of brickwork, and considered his case. He had been more than twelve hours without water under a fierce sun. His thirst would not increase so fast at night, but it would increase, nevertheless, and the Mexican force might linger below a week. Certainly its camp was of such a character that it would remain at least two or three days, and any risk was preferable to a death of thirst. He could wait no longer.
Now chance which had been so cruel flung a straw his way. The night was darker than usual. The moon and stars did not come out, and troops of clouds stalked up from the southwest. Ned knew that it was a land of little rain, and for a few moments he had a wild hope that in some manner he might catch enough water for his use on the crest of the pyramid. But reason soon drove the hope away. There was no depression which would hold water, and he resolved instead to make the descent under cover of the darkness.
When he had come to this resolution the thirst was not so fierce. Indecision being over, both his physical and mental courage rose. He ate and had left enough food to last for two days, which he fastened securely in a pack to his body. Then, machete in hand, he looked over the edge of the pyramid. There was some noise in the camp, but most of the soldiers seemed to be at rest. Lights flickered here and there, and the ruined city, showing only in fragments through the darkness, looked more ghostly and mournful than ever.
Ned waited a long time. Drops of rain began to fall, and the wind moaned with an almost human note around the pyramids and old walls. The rain increased a little, but it never fell in abundance. It and the wind were very cold, and Ned drew the serape very closely about his body. He was anxious now for time to pass fast, because he was beginning to feel afraid, not of the Mexicans, but of the dead city, and the ghosts of those vanished long ago, although he knew there were no such things. But the human note in the wind grew until it was like a shriek, and this shriek was to him a warning that he must go. The pyramid had been his salvation, but his time there was at an end.
He drew the sombrero far down over his eyes, and once more calculated the chances. He spoke Spanish well, and he spoke its Mexican variations equally well. If they saw him he might be able to pass for a Mexican. He must succeed.
He lowered himself from the crowning platform of the pyramid and began the descent. The cold rain pattered upon him and his body was weak from privation, but his spirit was strong, and with steady hand and foot he went down. He paused several times to look at the camp. Five or six fires still burned there, but they flickered wildly in the wind and rain. He judged that the sentinels would not watch well. For what must they watch, there in the heart of their own country?
But as he approached the bottom he saw two of these sentinels walking back and forth, their bayonets reflecting a flicker now and then from the flames. He saw also five or six large white tents, and he was quite sure that the largest sheltered at that instant Martin Perfecto de Cos, whom he wished very much to avoid. He intended, when he reached the bottom, to keep as close as he could in the shadow of the pyramid, and then seek the other side of the Teotihuacan.
The rain was still blown about by the wind, and it was very cold. But the influence of both wind and rain were inspiring to the boy. They were a tonic to body and mind, and he grew bolder as he came nearer to the ground. At last he stepped upon the level earth, and stood for a little while black and motionless against the pyramid.
He was aware that the cordon of Cos' army completely enclosed the Pyramid of the Moon, the Pyramid of the Sun, the Calle de los Muertos and the other principal ruins, and he now heard the sentinels much more distinctly as they walked back and forth. Straining his eyes he could see two of them, short, sallow men, musket on shoulder. The beat of one lay directly across the path that he had chosen, reaching from the far edge of the Pyramid of the Moon to a point about twenty yards away. He believed that when this sentinel marched to the other end of his beat he could slip by. At any rate, if he were seen he might make a successful flight,
