"How are we ever going to drive our horses through?" questioned Tad.
"That is easy when you know how," smiled Lilly.
"But it was all I could do to get through on foot when I was out the other day."
"You will find these horses are pretty handy in the swamp. The ordinary animal would be of no use at all. I will lead the way and show you something that will perhaps be new to you in forest travel."
"It is all new to me," answered Tad.
"All you folks have your horns with you in case we get separated. If you do, wind the horn until you get a reply."
"Wind your horn?" wondered Stacy Brown.
"Yes."
"What do you wind it with?"
"Oh, a piece of string," retorted Ned.
