"Here is a wall."

"No, it's a heap of stones."

"No, I am sure it's a wall."

Vitalis took a step aside to see if it really was as I said. He stretched out his two hands and touched the wall.

"Yes, it's a wall," he murmured. "Where is the entrance. Look for the track."

I stooped down to the ground and felt all along to the end of the wall, but I found no entrance; then, turning back to where Vitalis stood, I continued to feel along the wall on the other side. The result was the same; there was no opening, no gate.

"There is nothing," I said.

The situation was terrible. Without doubt my master was delirious. Perhaps there was no race-course here at all! Vitalis stood for a moment as though in a dream. Capi began to bark impatiently.

"Shall we look further?" I asked.
