"You are cold," I said; "if I can find anything dry enough to burn, we shall have a fire."

The girl came close to me. I could feel her body trembling against mine.

"I am a little cold," she said, "but that is nothing; I am terribly afraid."

"But why are you afraid now, Ozara? Do you think that Ul Vas will send men after us?"

"No, it is not that," she replied. "He couldn't make men come into this wood at night, and even by daylight they would hesitate to venture into it on this side of the river. Tomorrow he will know that it will be useless to send after us, for tomorrow we shall be dead."

"What makes you say that?" I demanded.

"The beasts," she said, "the beasts that hunt through the forest by night; we cannot escape them."

"Yet you came here willingly."

"Ul Vas would have tortured us," she replied; "the beasts will be more merciful. Listen! You can hear them now."

In the distance, I heard strange grunts and then a fearsome roar.

"They are not near us," I said.

"They will come," she replied.

"Then I had better get a fire started; that will keep them away."

"Do you think so?" she asked.

"I hope so."

I knew that in any forest there must be deadwood; and so, although it was pitch dark, I commenced to search for fallen branches; and soon I had collected a little pile of these and some dry leaves.

The Tarids had not taken away my pocket pouch, and in it I still had the common Martian appliance for making fire.

"You said that the Tarids would hesitate to enter the forest on this side of the river even by day," I remarked, as I sought to ignite the dry leaves with which I hoped to start my fire. "Why is that?"

"The Masenas," she replied. "They often come up the river in great numbers, hunting the Tarids; and unfortunate is he whom they find outside the castle walls. It is seldom, however, that they cross to the other side of the river."

"Why do they hunt the Tarids?" I asked. "What do they want of them?"

"Food," she replied.

"You don't mean to say that the Masenas eat human flesh?" I demanded.

She nodded. "Yes, they are very fond of it."

I had succeeded in igniting the leaves, and now I busied myself placing small twigs upon my newborn fire and building it up into the semblance of something worth while.

"But I was imprisoned for a long time with one of the Masenas," I reminded her.

"He seemed very friendly."

"Under those circumstances, of course," she said, "he might not try to eat you. He might even become very friendly; but if you should meet him here in the forest with his own people, you would find him very different. They are hunting beasts, like all of the other creatures, that inhabit the forest."

My fire grew to quite a respectable size. It illuminated the forest and the surface of the river and the castle beyond.
