"Harding, you are just the man I want, and you are in that very place where I need you, so you can return to your mine, and pretend to work as before, for there is where I wish you to serve me, since I received this letter from Doctor Dick."

"Thank you, Pard Cody, for your kindness, and will be glad to do as you wish; but may I ask a favor?"

"Certainly."

"It is that no one knows that I am in your service, not even Landlord Larry or Doctor Dick, for I can work better, I am sure."

"It might be a good idea to have it so, and it shall be as you wish, for you can do better work as a spy, and I have full confidence in you, Harding. But we will talk over just what it is best to do when I have reported to Major Randall the holding up of the coach and killing of Dave Dockery and the others."

Buffalo Bill then left the courier and went to headquarters, where he held a long conversation with the commandant of the post.

Returning to his own quarters he said to Harding, who was awaiting him:

"Well, pard, the major has heard the whole story, and he has left it to me to go in my own way about running down these road-agents, for, though only one was seen, there were evidently more at the hold-up."

"I do not doubt that, for one man would be a bold one to alone make an open attempt to hold up a coach with Dave Dockery on the box, and knowing that he had passengers with him."

"Well, Harding, you are to return to Last Chance, and give letters I will write to Landlord Larry, and I wish you to go to work in my service, and secret service it must be, for what you do must be underhand, no one knowing that you are doing else than carrying on your mining as before. I will give you a paper which will protect you, for Major Randall will endorse it officially, and you can use it in case of trouble, or necessity; not otherwise."
