Jack quickly threw his notebook and the Arctic book into his pack.
He started to follow them.
Then his gaze fell on the two bear masks.
He picked them up to get a better look.
Each was carved in the shape of a polar
bear's face with a blunt nose and roundish ears.
There were two holes for eyes and a strap to hold it on your head.
Suddenly howls split the air.
The dogs were barking and growling. Annie squealed.
Are the dogs attacking her? Jack wondered.
"Annie!"
Still holding the bear masks, Jack charged out of the igloo.
