As they drove farther along the road the cleared spaces became less frequent. The timber closed over the road and shut out the rays of the sun almost completely. There was no doubt now as to the presence of the smell of burning wood in the atmosphere. Finally they reached a point where they were under the smoke. The sun was almost entirely obliterated from view. It was just like traveling on a cloudy day. Prior to their reaching the smoke cloud, the sun had reflected itself from the bright leaves of the trees, but now there was just a red glow which marked the position of the sun.
