"I beg pardon," said the Lieutenant, reddening. "I didn't mean to cast doubt upon any of your statements, sir."

Thurstane had the army tone; he meant to be punctiliously polite; perhaps he was a little stiff in his politeness. But he was young, had had small practice in society, was somewhat hampered by modesty, and so sometimes made a blunder. Such things annoyed him excessively; a breach of etiquette seemed something like a breach of orders; hadn't meant to charge Coronado with drawing the long bow; couldn't help coloring about it. Didn't think much of Coronado, but stood somewhat in awe of him, as being four years older in time and a dozen years older in the ways of the world.

"I only meant to say," he continued, "that I have information concerning the Apaches which coincides with yours, sir. They are quiet, at least for the present. Indeed, I understand that Red Sleeve, or Manga Colorada, as you call him, is coming in with his band to make a treaty."

"Admirable!" cried Coronado. "Why not hire him to guarantee our safety? Set a thief to catch a thief. Why does not your Government do that sort of thing? Let the Apaches protect the emigrants, and the United States pay the Apaches. They would be the cheapest military force possible. That is the way the Turks manage the desert Arabs."

"Mr. Coronado, you ought to be Governor of New Mexico," said Aunt Maria, stricken with admiration at this project.

Thurstane looked at the two as if he considered them a couple of fools, each bigger than the other. Coronado advanced to Mrs. Stanley, took her hand, bowed over it, and murmured, "Let me have your influence at Washington, my dear Madame." The remarkable woman squirmed a little, fearing lest he should kiss her ringers, but nevertheless gave him a gracious smile.

"It strikes me, however," she said, "that the isthmus route is better. We know by experience that the journey from here to Bent's Fort is safe and easy. From there down the Arkansas and Missouri to St. Louis it is mostly water carriage; and from St. Louis you can sail anywhere."

Coronado was alarmed. He must put a stopper on this project. He called up all his resources.

"My dear Mrs. Stanley, allow me. Remember that emigrants move westward, and not eastward. Coming from Bent's Fort you had protection and company; but going towards it would be different. And then think what you would lose. The great American desert, as it is absurdly styled, is one of the most interesting regions on earth. Mrs. Stanley, did you ever hear of the Casas Grandes, the Casas de Montezuma, the ruined cities of New Mexico? In this so-called desert there was once an immense population. There was a civilization which rose, flourished, decayed, and disappeared without a historian. Nothing remains of it but the walls of its fortresses and palaces. Those you will see. They are wonderful. They are worth ten times the labor and danger which we shall encounter. Buildings eight hundred feet long by two hundred and fifty feet deep, Mrs. Stanley. The resting-places and wayside strongholds of the Aztecs on their route from the frozen North to found the Empire of the Montezumas! This whole region is strewn, and cumbered, and glorified with ruins. If we should go by the way of the San Juan—"

"The San Juan!" protested Thurstane. "Nobody goes by the way of the San Juan."
