As he did this, he saw some object move across the ice of the lake.
One object was followed by another, and then a third and a fourth.
"Animals of some kind," he thought. "But what?"
He watched the objects for several minutes.
They kept coming closer slowly, stopping every now and then, as if to deliberate. Then of a sudden, a lonely, mournful howl rent the air.
"Wolves!" he muttered. "They have discovered our camp and are coming towards it. I wonder what I had better do?"
CHAPTER VIII
THE FIRST NIGHT IN CAMP
Whopper was not much frightened. He had met wolves before and he did not think that the pack on the ice would dare to attack him and his friends. Nevertheless, to be on the safe side, he watched the beasts closely, and when they came still nearer he rushed into the shelter and grabbed up his shotgun.
"What's the row?" asked Shep sleepily, disturbed by the unusual bustle.
"Four wolves are on the ice in front of the shelter," explained
Whopper. "Reckon I'll give them a shot."
