I took from my pocket the paper I had found. It proved to be of heavy parchment, whitened by time; and I felt at once I was running on a true scent. There could be little doubt as to the age of the document. The ink was fading, the handwriting itself was in the style of long ago. The fact that the script was scratchy and uncertain, indicated that a man of meager education had written it. It was, however, perfectly legible. I judged that the date of the missive was at least ten or twenty years prior to the civil war.
