They found a cool little pool, an eddy or backwater, where the water standing over white sand was fairly clear, and the three, stripping, sprang in. The water was deep, and Bill plunged and dived and spluttered with great delight. Phil and Arenberg were not so noisy, but they found the bath an equal pleasure. It was an overwhelming luxury to get the sand out of their eyes and ears and hair, and to feel the cool water on bodies hot with the ache and grime of three days' hard work.

"You'd better make the best of it, Phil," said Breakstone. "The part of Mexico that we are going into isn't very strong on water, and maybe you won't get another bath for a year."

"I'm doing it," said the boy.

"And don't you mind the fact," said Bill Breakstone, "that the alligators of the Rio Grande, famous for their size and appet.i.te, like to lie around in lovely cool pools like this and bite the bare legs of careless boys who come down to bathe."

Phil felt something grasp his right leg and pull hard. He uttered a yell, and then, putting his hand on Breakstone's brown head, which was rising to the surface, convulsively thrust him back under. But Breakstone came up three yards away, pushed the hair out of his eyes, and laughed.

"I'm the only alligator that's in the stream," he said, "but I did give you a scare for a moment. You are bound to admit that, Sir Philip, Duke of Texas and Prince of Mexico."

"I admit it readily," replied Phil, and, noticing that Breakstone was now looking the other way, he dived quietly and ran his finger nails sharply along his comrade's bare calf. Breakstone leaped almost wholly out of the water and cried:

"Great Heavens, a shark is eating me up!"

Phil came up and said quietly:

"There are no sharks in the Rio Grande, Mr. William Breakstone. You never find sharks up a river hundreds of miles from the ocean. Now, I did give you a scare for a moment, you will admit that, will you not, Sir William of the Shout, the Shark, and the Fright?"

"I admit it, of course, and now we are even," said Breakstone. "Give me your hand on it."

Phil promptly reached out his hand, and Breakstone, seizing it, dragged him under. But Phil, although surprised, pulled down on Breakstone's hand with all his might, and Breakstone went under with him. Both came up spluttering, laughing, and enjoying themselves hugely, while Arenberg swam calmly to a safe distance.

"You are a big boy, Herr Bill Breakstone," he said. "You will never grow up."

"I don't want to," replied Bill Breakstone calmly. "When it makes me happy all through and through just to be swimming around in a pool of nice cool water, what's the use of growing up? Answer me that, Hans Arenberg."

"I can't," replied the German. "It isn't in me to give an answer to such a question."

"I suppose we've got to go out at last, dress again, and go back to work," said Breakstone lugubriously. "It's a hard world for us men, Phil."

"One iss not a fish, and, being not a fish," said Arenberg, "one must go out on dry land some time or other to rest, and the some time has now come."

They swam to land, but Bill Breakstone began to plead.

"Let's lie here on the sand and luxuriate for a s.p.a.ce, Sir Philip of the Rio Grande and Count Hans of the Llano Estacado, which is Spanish for the Staked Plain, which I have seen more than once," said Bill Breakstone. "The sand is white, it is clean, and it has been waiting a long time for us to lie upon it, close our eyes, and forget everything except that we are happy."

"It iss a good idea," said Arenberg. "There are times when it iss well to be lazy, only most men think it iss all the time."

They stretched themselves out on the white sand and let the warm sun play upon them, permeating their bodies and soothing and relaxing every muscle. Phil had not felt so peaceful in a long time. It had relieved him to tell the secret of his quest to Breakstone, who, with his permission, had told it in turn to Middleton and Arenberg, and now that he was really in Mexico with strong friends around him he felt that the first great step had been accomplished. The warm sun felt exceedingly good, his eyes were closed, and a pleasant darkness veiled them, a faint murmur, the flowing of the river, came to his ears, and he floated away with the current.

"Here! here! Sir Philip of the Sleepy Head, wake up. It isn't your first duty to go to sleep when you arrive in Mexico! Besides, it's time we were back at the camp, or they'll think Santa Anna has got us already! Also, you need more clothes than you've got on just now!"

Phil sprang up embarra.s.sed, but he saw Arenberg looking sheepish, also.

"You had good company, Sir Philip of the Sleepy Head," exclaimed Breakstone joyously. "Count Hans, of the Snore was traveling with you into that unknown land to which millions have gone and returned, and of which not one can tell anything."

"It iss so," said Arenberg. "I confess my weakness."

They dressed rapidly, and, refreshed and young again, ran back to the train. The twilight was now coming, and the wagons were drawn up in the usual circular formation, with the animals in the middle, and, outside the circle, were burning several fires of dry cactus and cottonwood, around which men were cooking.

"Just in time for supper," said Bill Breakstone. "I was a great rover when I was a boy, but my mother said I took care never to get out of sound of the dinner-bell. It may be funny, but my appet.i.te is just as good in Mexico as it was in Texas."

They ate strips of bacon, venison, and jerked buffalo, with a great appet.i.te. They drank coffee and felt themselves becoming giants in strength. The twilight pa.s.sed, and a brilliant moon came out, flooding the plain with silvery light. Then they saw a horseman coming toward them, riding directly through the silver flood, black, gigantic, and sinister.

"Now what under the sun can that be?" exclaimed Bill Breakstone.

"You should say what under the moon. It iss more correct," said Arenberg. "I can tell you, also, that it iss a white man, although the figure looks black here--I know by the shape. It iss also an American officer in uniform. I know it because I saw just then a gleam of moonlight on his epaulets. He iss coming to inspect us."

The approach of the stranger aroused, of course, the deepest curiosity in everybody, and in a few moments a crowd gathered to gaze at this man who came on with such steadiness and a.s.surance. His figure, still magnified by the moon, out of which he seemed to be riding, showed now in perfect outline. He carried no rifle, but they could see the hilt of a sword on his thigh. He wore a military cap, and the least experienced could no longer doubt that he was an army officer.

"He knows that we are friends," said Middleton, "or he would not come on so boldly. Unless I mistake much, he sits his horse like a regular officer of the United States cavalry. That seat was learned only at West Point."

The stranger rode out of the magnifying rays. His horse and himself shrank to their real size. He came straight to the group, leaped to the ground, and, holding the bridle in one hand, lifted his cap with the other in salute. Middleton sprang forward.

"Edgeworth," he exclaimed, "when you came near I thought it was you, but I scarcely dared to hope."

The officer, tall and striking of appearance, with penetrating gray eyes, seized Middleton's hand.

"And it is you, Middleton," he said. "What a meeting for two who have not seen each other since they were at West Point together."

"But it's where we both want to be," said Middleton.

"That is so," said Edgeworth with emphasis, "but I had heard, George, that you were sent on an errand of uncommon danger, and I had feared--I will not hesitate to say it to you now--that you would never come back."

Middleton laughed. He was obviously delighted with this meeting of the comrade of his cadetship. Then he introduced Woodfall and the others, after which he asked:

"How did you know we were friends, Tom? You came on as if you were riding to a garden-party."

"A scout brought news of you," he replied. "We have a small force about twenty miles ahead, and I rode back to meet you, and see what was here."

"We have some good men," said Woodfall, "and they are willing to fight.

We've come a good many hundreds of miles for that purpose."

"I believe you," said Edgeworth, running his trained eyes over the crowd. "A finer body of men I never saw, and we need you, every one of you."

"What news?" asked Middleton eagerly.

"Much of it, and all bad. Our government has mixed the situation badly.

We've been steadily strengthening Scott, and, in the same proportion, we've been weakening Taylor. There are rumors, I don't know how authentic--perhaps you have heard them--that Santa Anna is coming north with a great force to destroy us. Taylor is expected to retreat rapidly, but he hasn't done it. You know old Rough and Ready, George."

"I hope to Heaven he won't retreat!" exclaimed Middleton.

"He hasn't. So far he has advanced," said Edgeworth. "But I ride back with you in the morning, boys, and I think great things are going to happen before long. Besides the men with you, Middleton, we've use for everything you've got in the wagons. You won't suffer, Mr. Woodfall."

The train moved the next morning an hour earlier than usual. Wheels were turning before daylight. Hearts were beating high, and they pushed on at great speed now, for wagons, until past sunset. In the middle of the day it was hot, in the evening chill winds blew down from the crests of distant mountains, but at all times, morning, noon, and evening, they marched in a cloud of dust, much of it impregnated with alkali. It annoyed Phil and his comrades terribly, sifting into nose, mouth, ears, and eyes, putting a bitter taste on the palate, and making them long for the sweet waters of the pool in which they had bathed so luxuriously.

The next day was the same; more dust, more alkali, and the deadly monotony of a treeless and sandy plain. But that night it was extremely cold. They were approaching the mountains, the spurs of the Sierra Madre, and the winds were sharp with the touch of ice and snow. Winter, also, had come, and in the night ice formed in the infrequent rivulets on the plain. Now and then they pa.s.sed little Mexican villages, mostly of the adobe huts, with dirt and children strewed about in great quant.i.ties. The children were friendly enough, but the women scowled, and the men were away. Phil did not find the villages picturesque or attractive in any sense, and he was disappointed.
