"What is it?" Bob breathed.
"There's something or someone out there."
"I don't hear a thing," Bob whispered.
"Listen."
"I hear it now," as another twig snapped, answered by an angry snarl from one of the dogs which awoke Lucky.
"What matter with dog?" he whispered as soon as he saw that the boys were awake.
"There's something prowling around the camp," Bob told him.
"Injun go see."
"Reckon we'd better all go," Bob said as he began to squirm out of his bag.
There was only a small rim of the moon showing, but the sky was filled with stars and it was not dark. In fact Bob could see for some distance through the woods as he carefully raised his eyes over the edge of the snow. At first he saw nothing to cause him any alarm, but after a moment of watching he caught sight of a shadowy form stealing from behind a large tree about thirty feet away to the security of another some ten feet nearer.
