“My dear, don’t ask me! I tell you frankly, I’m nonplussed. You were somebody else a minute ago.... The truth is, of course, you’ve been dreaming awake. Has any one else seen you beside me?”

“Have I been out of my room?” asked Miriam, in dismay.

“You must have been, I should think, to get that costume. Well, the best plan will be, I suppose, to say nothing about it to anybody. It shall be our secret, dear. If I were you, I would have one of the women sleep in your room, in case you got restless again. It’s just an attack of nervousness, probably,—having so many strangers in the house, all of a sudden. Now you must go to bed and get to sleep: it’s awfully late, and there’ll be ever so much going on to-morrow.”

Grace herself slept little that night. She could not decide what to make of this adventure. Nowadays we are provided with a name for the peculiar psychical state which Miriam was undergoing, and with abundant instances and illustrations; but we perhaps know what it is no more than we did twenty-five or thirty years ago. Grace’s first idea had been that Miriam was demented; then she thought she was playing a part; then she did not know what to think; and finally she came to the conclusion that it was best to quietly await further developments. She would keep an eye on Freeman as well as on Miriam; something, too, might be gathered from Don Miguel; and then there was that talk about a treasure. Was that all the fabric of a dream, or was there truth at the bottom of it? She had heard something said about a treasure in the course of the general conversation the day before. If there really was a treasure, why might not she have a hand in the discovery of it? Miriam, in her abnormal state, had let fall some topographical hints that might prove useful. Well, she would work out the problem, sooner or later. To-morrow, when the others had gone off on their expedition, she would have ample leisure to sound Don Miguel, and, if he proved communicative and available, who could tell what might happen? But how very odd it all was! Who was Semitzin?

While asking herself this question, Grace fell asleep; and by the time the summons to breakfast came, she had passed through thrilling adventures enough to occupy a new Scheherazade at least three years in the telling of them.

CHAPTER VI.

By nine o’clock in the morning, Professor Meschines and Harvey Freeman had ridden up to the general’s ranch, equipped for the expedition. The general’s preparations were not yet quite completed. A couple of mules were being loaded with the necessary outfit. It was proposed to be out two days, camping in the open during the intervening night. It was necessary to take water as well as solid provisions. Leaving their horses in the care of a couple of stable-boys, Meschines and Freeman mounted the veranda, and were there greeted by General Trednoke.

“I’m afraid we’ll have a hot ride of it,” he observed. “The atmosphere is rather oppressive. Kamaiakan tells me there was a touch of earthquake last night.”

“I thought I noticed some disturbance,——” returned the professor, with a stealthy side-glance at Freeman,—“something in the nature of an explosion.”
