Frank could now hear what they said.
"Mad dog! mad dog!" "Get through the hedge, Charlie, quick," Frank cried.

"Here, I will help you over, never mind the thorns." The hedge was low and closely kept, and Frank, bundling his comrade over it, threw himself across and looked round.

The dog was within ten yards of them, and Frank saw that the alarm was well founded.

The dog was a large crossbred animal, between a mastiff and a bulldog.

Its hair was rough and bristling.
