"Delusion, sir?" she exclaimed. "You forget yourself. It is the most real thing in the world to him. Be careful how you make use of such expressions here. I advise you also not to forget that you are still my father's prisoner."

She spoke with so much earnestness that I was impressed, more from fear that I had wounded her feelings than from fear for myself. I felt confident yet that it was the year 1896; and that all the world was at peace, barring the little wars of England, which don't count. She took me no further than the great parlor—or the armory, if its fit name be applied. My unfortunate question seemed to make some change in her intentions, and she suggested that we walk outside on the terrace.

It was a delight as keen as any I had ever felt to step out after imprisonment into the brilliant sunshine of the free and open world. Miss Hetherill threw a light cloak over her shoulders, for there was a sharp coolness in the air, and together we strolled over the terrace. I admired the solidity and strength of Fort Defiance, though a good-sized modern cannon could have knocked it to pieces with ease, if any one were ever able to get a cannon over the maze of mountains that separated this valley from the remainder of the world. It was impregnable to attack by small arms, if well guarded. The drawbridge was still up, and I spoke of it.

"It is up most of the time," she said, frankly, "but to-day it will be up more than usual. That is on your account. You are to be kept well guarded."

"The current of the river is too swift," I said; "but I think I could swim the moat."

"If you succeeded," she said, "you would probably starve to death in the mountains."

"Then I shall remain here," I said. "I'm glad that I have so good an excuse for remaining."

I sought to be gallant, but she only frowned, and I did not attempt it again. She left me presently, going into the house, while I continued my stroll in the crisp, invigorating air. I could take but a limited walk at best, merely the circuit of the hill-top, embracing perhaps a couple of acres around the house. Within that space I could wander at will, and no watch seemed to be set upon me.
