"Ben," said Bradley, "the best way for us to arrange will be to take turns in riding. I'd a good deal rather walk half the way. My legs get cramped when I am on horseback too long. You remember I used to get off and lead the horse when we had one apiece. You may take your turn first, and as you are riding I will give you a bag to carry. Mind you don't lose it, for it contains our store of gold-dust."
