A mile from here is a hillock within hearing of the stockade at Robertson's Ford.

One shot fired there will tell them what you want them to know.

Robertson's will fire twice for Appleby's to hear, and Appleby's will send on the message to Dopple's.

There are six posts between here and the South Fork, so when the folk at Frew's hear seven shots they will know that the war is on the Rappahannock." I recognized old Lawrence's hand in this.

It was just the kind of device that he would contrive.
