“Maybe it was only a reflection of the blaze at that,” I said.

“Do I have to get up?” Brent asked.

This outline is a crude reproduction of the markings that Brent noticed in the cement of the hearth. Of course it does not show the depressions. If you will imagine the large area as a depression, and the five smaller enclosures as depressions, with all of the outlines less distinct, you will have an idea of the imprint as we saw it.

Lantern in hand, Tom went to the door, and as he opened it a gust of wind rushed in, blowing a lot of papers from the open cupboard, and banging the cupboard door furiously back and forth. Through the window we could see the light of the lantern moving about outside. Suddenly I was moved to join Tom and together we went over to the other building and quietly opened the door.
